Access Pandas MultiIndex column by name - python-2.7

I have a spreadsheet imported with pandas like this:
df = pd.read_excel('my_spreadsheet.xlsx',header = [0,1],index_col=0,sheetname='Sheet1')
The output of df.columns is:
MultiIndex(levels=[[u'MR 1', u'MR 10', u'MR 11', u'MR 12', u'MR 13', u'MR 14', u'MR 15', u'MR 16', u'MR 17', u'MR 18', u'MR 19', u'MR 2', u'MR 20', u'MR 21', u'MR 22', u'MR 3', u'MR 4', u'MR 5', u'MR 6', u'MR 7', u'MR 8', u'MR 9'], [u'BIRADS', u'ExamDesc', u'completedDTTM']],
labels=[[0, 0, 0, 11, 11, 11, 15, 15, 15, 16, 16, 16, 17, 17, 17, 18, 18, 18, 19, 19, 19, 20, 20, 20, 21, 21, 21, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 9, 10, 10, 10, 12, 12, 12, 13, 13, 13, 14, 14, 14], [1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0]],
names=[None, u'De-Identified MRN'])
I have been trying to access the values of column named 'De-Identified MRN', but can't seem to find the way to do this.
What I have tried (based on similar posts):
[in] df.index.get_level_values('De-Identified MRN')
[out] KeyError: 'Level De-Identified MRN must be same as name (None)'
and
[in] df.index.unique(level='De-Identified MRN')
[out] KeyError: 'Level De-Identified MRN must be same as name (None)'
UPDATE:
The following did the trick for some reason. I really do not understand the format of the MultiIndex Pandas Dataframe:
pd.Series(df.index)

By using your data
s="MultiIndex(levels=[[u'MR 1', u'MR 10', u'MR 11', u'MR 12', u'MR 13', u'MR 14', u'MR 15', u'MR 16', u'MR 17', u'MR 18', u'MR 19', u'MR 2', u'MR 20', u'MR 21', u'MR 22', u'MR 3', u'MR 4', u'MR 5', u'MR 6', u'MR 7', u'MR 8', u'MR 9'], [u'BIRADS', u'ExamDesc', u'completedDTTM']],labels=[[0, 0, 0, 11, 11, 11, 15, 15, 15, 16, 16, 16, 17, 17, 17, 18, 18, 18, 19, 19, 19, 20, 20, 20, 21, 21, 21, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 9, 10, 10, 10, 12, 12, 12, 13, 13, 13, 14, 14, 14], [1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0]],names=[None, u'De-Identified MRN'])"
idx=eval(s, {}, {'MultiIndex': pd.MultiIndex})
df=pd.DataFrame(index=idx)
df.index.get_level_values(level=1) # df.index.get_level_values('De-Identified MRN')
Out[336]:
Index(['ExamDesc', 'completedDTTM', 'BIRADS', 'ExamDesc', 'completedDTTM',
'BIRADS', 'ExamDesc', 'completedDTTM', 'BIRADS', 'ExamDesc',...
Also if all above still does not work , try
df.reset_index()['De-Identified MRN']

Try the following:
midx = pd.MultiIndex(
levels=[[u'MR 1', u'MR 10', u'MR 11', u'MR 12', u'MR 13', u'MR 14', u'MR 15', u'MR 16', u'MR 17', u'MR 18', u'MR 19', u'MR 2', u'MR 20', u'MR 21', u'MR 22', u'MR 3', u'MR 4', u'MR 5', u'MR 6', u'MR 7', u'MR 8', u'MR 9'], [u'BIRADS', u'ExamDesc', u'completedDTTM']],
labels=[[0, 0, 0, 11, 11, 11, 15, 15, 15, 16, 16, 16, 17, 17, 17, 18, 18, 18, 19, 19, 19, 20, 20, 20, 21, 21, 21, 1, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7, 8, 8, 8, 9, 9, 9, 10, 10, 10, 12, 12, 12, 13, 13, 13, 14, 14, 14], [1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0, 1, 2, 0]],
names=[None, u'De-Identified MRN']
)
midx.levels[1] # returns the following
Index(['BIRADS', 'ExamDesc', 'completedDTTM'], dtype='object', name='De-Identified MRN')
midx.levels[1].values # returns the following

How to split list based on values in Python?

I have a list that needs to copied multiply times by the number at an index.
here is an example to help explain.
The original list:
[AAA, Bus, Apple, 5, 3, 1, Car, 22, 30]
what is needs to become:
aList = [
[AAA, Bus, Apple, 1, 1, 1, Car, 22, 30]
[AAA, Bus, Apple, 1, 1, 0, Car, 22, 30]
[AAA, Bus, Apple, 1, 1, 0, Car, 22, 30]
[AAA, Bus, Apple, 1, 0, 0, Car, 22, 30]
[AAA, Bus, Apple, 1, 0, 0, Car, 22, 30]
]
All the list are in the same order to I can view the values bu index.
Thanks
I hope I've understood your question right. This example will copy the list by maximal number found in list:
lst = ["AAA", "Bus", "Apple", 5, 3, 1, "Car"]
n = max((v for v in lst if isinstance(v, int)), default=0)
out = [lst]
for _ in range(n - 1):
out.append([(v - 1) if isinstance(v, int) else v for v in out[-1]])
out = [[int(v > 0) if isinstance(v, int) else v for v in l] for l in out]
print(*out, sep="\n")
Prints:
['AAA', 'Bus', 'Apple', 1, 1, 1, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']
EDIT: To change only specified indices:
lst = ["AAA", "Bus", "Apple", 5, 3, 1, "Car"]
n = max(v for v in lst[3:6])
out = [lst[3:6]]
for _ in range(n - 1):
out.append([v - 1 for v in out[-1]])
out = [lst[:3] + [int(v > 0) for v in l] + lst[6:] for l in out]
print(*out, sep="\n")
Prints:
['AAA', 'Bus', 'Apple', 1, 1, 1, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']

How add 0 when TruncWeek's week no result in Django Query?

I want query the issue's count of group by weekly.
query1 = MyModel.object.filter(issue_creator__in=group.user_set.all()).\
annotate(week=TruncWeek('issue_creat_date')).values('week').annotate(count=Count('id')).order_by('week'))
the query result is OK. the queryset result:
[
{'week': datetime.datetime(2022, 1, 3, 0, 0, tzinfo=<DstTzInfo 'Europe/Stockholm' CEST+2:00:00 DST>), 'count': 9},
{'week': datetime.datetime(2022, 1, 10, 0, 0, tzinfo=<DstTzInfo 'Europe/Stockholm' CEST+2:00:00 DST>), 'count': 12},

{'week': datetime.datetime(2022, 2, 28, 0, 0, tzinfo=<DstTzInfo 'Europe/Stockholm' CEST+2:00:00 DST>), 'count': 1}
]
but 20220101-20220301 has 9 weeks:
[
datetime.datetime(2022, 1, 3, 0, 0, tzinfo=<DstTzInfo 'Europe/Stockholm' CEST+2:00:00 DST>),

I want add zero when that week no result as this result:
[

how to write the right queryset?
Thanks.
Django method for None value Coalesce.
from django.db.models.functions import Coalesce
query1 = MyModel.object.filter(issue_creator__in=group.user_set.all()).\
annotate(week=TruncWeek('issue_creat_date')).values('week').annotate(count=Count('id')).order_by('week'))

Django ORM queryset equivalent to group by year-month?

I have an Django app and need some datavisualization and I am blocked with ORM.
I have a models Orders with a field created_at and I want to present data with a diagram bar (number / year-month) in a dashboard template.
So I need to aggregate/annotate data from my model but did find a complete solution.
I find partial answer with TruncMonth and read about serializers but wonder if there is a simpliest solution with Django ORM possibilities...
In Postgresql it would be:
SELECT date_trunc('month',created_at), count(order_id) FROM "Orders" GROUP BY date_trunc('month',created_at) ORDER BY date_trunc('month',created_at);
"2021-01-01 00:00:00+01" "2"
"2021-02-01 00:00:00+01" "3"
"2021-03-01 00:00:00+01" "3"
...
example
1 "2021-01-04 07:42:03+01"
2 "2021-01-24 13:59:44+01"
3 "2021-02-06 03:29:11+01"
4 "2021-02-06 08:21:15+01"
5 "2021-02-13 10:38:36+01"
6 "2021-03-01 12:52:22+01"
7 "2021-03-06 08:04:28+01"
8 "2021-03-11 16:58:56+01"
9 "2022-03-25 21:40:10+01"
10 "2022-04-04 02:12:29+02"
11 "2022-04-13 08:24:23+02"
12 "2022-05-08 06:48:25+02"
13 "2022-05-19 15:40:12+02"
14 "2022-06-01 11:29:36+02"
15 "2022-06-05 02:15:05+02"
16 "2022-06-05 03:08:22+02"
expected result
[
{
"year-month": "2021-01",
"number" : 2
},
{
"year-month": "2021-03",
"number" : 3
},
{
"year-month": "2021-03",
"number" : 3
},
{
"year-month": "2021-03",
"number" : 1
},
{
"year-month": "2021-04",
"number" : 2
},
{
"year-month": "2021-05",
"number" : 3
},
{
"year-month": "2021-06",
"number" : 3
},
]
I have done this but I am not able to order by date:
Orders.objects.annotate(month=TruncMonth('created_at')).values('month').annotate(number=Count('order_id')).values('month', 'number').order_by()
<SafeDeleteQueryset [
{'month': datetime.datetime(2022, 3, 1, 0, 0, tzinfo=<UTC>), 'number': 4},
{'month': datetime.datetime(2022, 6, 1, 0, 0, tzinfo=<UTC>), 'number': 2},
{'month': datetime.datetime(2022, 5, 1, 0, 0, tzinfo=<UTC>), 'number': 1},
{'month': datetime.datetime(2022, 1, 1, 0, 0, tzinfo=<UTC>), 'number': 5},
{'month': datetime.datetime(2021, 12, 1, 0, 0, tzinfo=<UTC>), 'number': 1},
{'month': datetime.datetime(2022, 7, 1, 0, 0, tzinfo=<UTC>), 'number': 1},
{'month': datetime.datetime(2021, 9, 1, 0, 0, tzinfo=<UTC>), 'number': 2},
'...(remaining elements truncated)...'
]>
Try adding the order_by on the original field if you have multi-year data.
from django.db.models import Sum
from django.db.models.functions import TruncMonth
Orders.objects.values(month=TruncMonth('created_at')).
order_by("created_at").annotate(Sum('number')

Google Charts is not displaying last row in the data array?

I have data array with 45 rows but only 44 rows are visible on the screen after I am hide columns between 8 and 14 using "setColumns" and then re-enable any of the columns between 8 and 14:
The 45th row has following data:
0:{wf: "10 May 2018, 14:44:36"}
1:{wf: ""}
2:{wf: ""}
3:{wf: ""}
4:{wf: ""}
5:{wf: ""}
6:{wf: ""}
7:{wf: ""}
8:{wf: "69.9"}
9:{wf: "73.2"}
10:{wf: "65.2"}
11:{wf: "73.2"}
12:{wf: "82.8"}
13:{wf: "0"}
14:{wf: "28.6"}
To perform column toggle I use following commands:
performColumnToggle: function (col)
{
// use original unfiltered data
_view = new google.visualization.DataView(_original_data);
// get a key due to splice not keeping keys one delete
var key = $.inArray(col, _toggledColumns);
if (_columns[col]['status'] === 1) {
_columns[col]['status'] = 0;
// delete by key because splice doesn't keep keys on delete
_toggledColumns.splice(key, 1);
} else {
_columns[col]['status'] = 1;
// insert new items with a key and push other columns
_toggledColumns.splice(col, 0, col);
}
// set columns to display
_view.setColumns(_toggledColumns);
console.log(_chart.getDataTable().getNumberOfRows()); // keeps returns 44 rather then 45.
_dashboard.draw(_view);
}
I set _original_data when I first initiate the chart and when I have to update the data in the chart. When I perform console.log(_original_data) I see all 45 rows.
init_chart: function ()
{
_data = new google.visualization.DataTable(_tableData);
_original_data = _data;
// some other code ....
}
updateData: function ()
{
_tableData = data;
_data = new google.visualization.DataTable(_tableData);
_original_data = _data;
// some other code ....
}
Below is an example code
https://jsfiddle.net/Spiker/g0k714h7/
To trigger error take following steps:
Scroll down the page you will notice that we have 45 rows with last row having time date "10 May 2018, 14:44:36"
Scroll back up and click on "Select/Diselect All". You can scroll down the table to see that now we have 44 rows
Either Click on "Select/Diselect All" or "record8". Scroll down the page to see that we still have 44 rows in the table
DataView Class
.hideColumns() Method
DataView Class is a special version of the DataTable Class. Its main purpose is to present a part(s) of the DataTable(s). OP code needs to toggle columns with the method that compliments .setColumns() which is .hideColumns().
In Demo 1 below there is a ternary that toggles the columns from [0,...14] to [8...14] columns by using both set/hideColumns() methods. The table has 90 rows and it persists at 90 between toggling of columns.
Example
var dView = *status === 'on' ?
view.setColumns([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]) :
view.hideColumns([0, 1, 2, 3, 4, 5, 6, 7]);
⭐ Demo 2 (located at the bottom of this post,) isn't a solution but it could help the OP code should you decide on not using Demo 1.

⭐Although I strongly suggest that you use the hideColumns() from Google Visualization API, I'd like to address this:
"// delete by key because splice doesn't keep keys on delete "
splice() returns whatever it deletes. So you call on splice() and store its return in a var, const, array, object, etc.
Demo 2
var columnArray = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14];
var removedArray = columnArray.splice(0, 8);
console.log('Removed Column Array: ' + removedArray);
console.log('Remaining Column Array: ' + columnArray);
var restoredArray = removedArray.concat(columnArray);
console.log('Restored Column Array: ' + restoredArray);
the problem appears to occur in function --> switchOffAllColumns
there must be some sort of bug with the view
setting the view columns on the ChartWrapper, rather than the DataView,
corrects the issue
in switchOffAllColumns, change the following line...
_view.setColumns(_toggledColumns);
to...
_chart.setView({
columns: _toggledColumns
});
see following working fiddle...

note: jsapi should no longer be used, changed above fiddle to use loader.js load statement...

CouchDB unable to Reduce Function

Hi all im starting to work with couchdb
im trying to rereduce this reduce function
function(key,values,rereduce){
if(rereduce === true){
//HELP HERE
return results;
}
values.forEach(function(doc){
if(results[(doc.id-1)]){
results[(doc.id-1)].valori.push(doc.valore);
}else{
results[(doc.id-1)] = {
id:doc.id,
nome:doc.nome,
unita:doc.unita,
valori:[doc.valore]
};
}
});
return results;
}
someone can help me to rereduce this?
this is my Map output data
[2015, 7, 6, 0, 0, 26]

{nome: "COT ist.INGRESSO ", valore: 306.7, id: 1, unita: "mg/Nm", ora: "00:02:26"}
etc....
What i need after the reduce is:
[{nome:"COT ist.Ingresso", id:1, unita:"mg/Nm",valori:[309.6,5.4,.....]}
{name:"thename",id:2, unita:"mg/Nm",valori:[6.8,3.5,......]}...]
this is an array of 4 object (one each id) with valori field is the concat of the various valore field, ( ordered by key or ora property)
