I am using a for loop for getting data from the user in command prompt using python 2.7. Then storing the data in a text file in certain format. I am looking for a method to get the data from the user and store it in a list and use it where required.
for Input_Number in range(Number_Of_Inputs):
Input_Number = Input_Number+1
GUI_Parameter = str(raw_input("Please enter input parameter " + str(Input_Number) + " :"))
GUI_Parameter_Name = str(raw_input("Enter the GUI name for the parameter " + str(Input_Number) + " :"))
Store_GUI_Parameter(Opened_File, GUI_Parameter, GUI_Parameter_Name)
I would like to use this data to store it in a specific location in a text file according to required syntax. The above code stores the data in the text file. But the problem is it doesn't store it at the required place.
def Store_GUI_Parameter(Opened_File, GUI_Parameter, GUI_Parameter_Name):
GUI_Description = "| " + '"'+ GUI_Parameter_Name + '"' + " |$" + GUI_Parameter.title() + " |"
Write_Data(Opened_File, GUI_Description)
print "GUI parameters written to NDF file"
return
The data storage is done using the above function...
I tried this, but unfortunately this also is not working
GUI_Parameter= []
GUI_Parameter_Name = []
for Input_Number in range(Number_Of_Inputs):
Input_Number = Input_Number+1
GUI_Parameter[Input_Number] = str(raw_input("Please enter input parameter " + str(Input_Number) + " :"))
GUI_Parameter_Name[Input_Number] = str(raw_input("Enter the GUI name for the parameter " + str(Input_Number) + " :"))
Using it outside the loop in the same function...
GUI_Description(Opened_File, GUI_Parameter_Name[Input_Number], GUI_Parameter[Input_Number])
The function implementation:
def GUI_Description(Opened_File, GUI_Parameter_Name[Input_Number], GUI_Parameter[Input_Number]):
Iteration = 0
while Iteration < Input_Number:
Iteration += 1
GUI_Description = "| " + '"'+ GUI_Parameter_Name[Input_Number] + '"' + " |$" + GUI_Parameter[Input_Number].title() + " |"
Write_Data(Opened_File, GUI_Description)
print "GUI parameters written to NDF file"
return
But it shows syntax error at the def GUI_Description
C:\Users\padmanab\Desktop>python CtoN.py File "CtoN.py", line 173
def GUI_Description(Opened_File, GUI_Parameter_Name[Input_Number], GUI_Parameter[Input_Number]):
^ SyntaxError: invalid syntax
The syntax error in the function GUI_Description is caused by your input arguments. 'GUI_Parameter_Name[Input_Number]' is not a valid input argument. Since your function requires both 'GUI_Parameter_Name' and 'Input_Number' they should be separate input arguments. The code snippet below would solve this syntax error:
def GUI_Description(Opened_File, Input_Number, GUI_Parameter_Name, GUI_Parameter):
...
The code below will give an 'index out of range' error since the lists 'GUI_Parameter' and 'GUI_Parameter_Name' have zero length.
GUI_Parameter= []
GUI_Parameter_Name = []
Number_Of_Inputs = 1
for Input_Number in range(Number_Of_Inputs):
Input_Number = Input_Number+1
GUI_Parameter[Input_Number] = str(raw_input("Please enter input parameter " + str(Input_Number) + " :"))
GUI_Parameter_Name[Input_Number] = str(raw_input("Enter the GUI name for the parameter " + str(Input_Number) + " :"))
If you want to add items to the arrays you should append them:
GUI_Parameter.append(raw_input())

I am working on this project where i have 3 string variables which I want to email their values to an email address. I was able to email a plain text message; however, I couldn't include these variables values in. Below is my codes:
import serial
import smtplib
import time
serialport = serial.Serial('/dev/ttyUSB0', 115200, timeout = 0.5)
user= 'user#gmail.com'
password= 'password'
receiver= 'receiver#gmail.com
subject= 'Solar tracker status'
header = 'To: ' + email + '\n' + 'From: ' + email + '\n' + 'Subject: ' +
subject
while True:
line = serialport.readline()
result = line.find(";")
if result > 0:
str = line.split(";")
volt=str[0]
power=str[1]
temp=str[2]
body = "\n" + + "Voltage: " + volt + "\n" + "Power: " + power + "\n" + "Temp: " + temp
print header + '\n' + body
s=smtplib.SMTP('smtp.gmail.com',587)
s.ehlo()
s.starttls()
s.ehlo()
s.login(email, password)
s.sendmail(email, email, header + '\n\n' + body)
s.quit
When running this script, i got this error message :
File "testserial.py", line 23, in <module>
body = "\n" + + "Voltage: " + volt
TypeError: bad operand type for unary +: 'str'
I have tried converting the variable into string using str(volt), then got this error message:
File "testserial.py", line 23, in <module>
str(volt)
TypeError: 'list' object is not callable
I can't understand this because they are originally in string format since i was able to write them into a text file using %s without having to convert it.
I think i just don't know how to pass a variable into the body of the email.
Please help!
I am working on a script that sorts people's names. I had this working using the csv module, but as this is going to be tied to a larger pandas project, I thought I would convert it.
I need to split a single name field into fields for first, middle and last. The original field has the first name first. ex: Richard Wayne Van Dyke.
I split the names but want "Van Dyke" to be the last name.
Here is my code for the csv module that works:
with open('inputfil.csv') as inf:
docs = csv.reader(inf)
next(ccaddocs, None)
for i in docs:
#print i
fullname = i[1]#it's the second column in the input file
namelist =fullname.split(' ')
firstname = namelist[0]
middlename = namelist[1]
if len(namelist) == 2:
lastname = namelist[1]
middlename = ''
elif len(namelist) == 3:
lastname = namelist[2]
elif len(namelist) == 4:
lastname = namelist[2] + " " + namelist[3] #gets Van Dyke in lastname
print "First: " + firstname + " middle: " + middlename + " last: " + lastname
Here is my pandas-based code that I'm struggling with:
df = pd.DataFrame({'Name':['Richard Wayne Van Dyke','Gary Del Barco','Dave Allen Smith']})
df = df.fillna('')
df =df.astype(unicode)
splits = df['Name'].str.split(' ', expand=True)
df['firstName'] = splits[0]
if splits[2].notnull and splits[3].isnull:#this works for Bret Allen Cardwell
df['lastName'] = splits[2]
df['middleName'] = splits[1]
print "Case 1: First: " + df['firstName'] + " middle: " +df['middleName'] + " last: " + df['lastName']
elif splits[2].all() == 'Del':#trying to get last name of "Del Barco"
print 'del'
df['middleName'] = ''
df['lastName'] = splits[2] + " " + splits[3]
print "Case 2: First: " + df['firstName'] + " middle: " +df['middleName'] + " last: " + df['lastName']
elif splits[3].notnull: #trying to get last name of "Van Dyke"
df['middleName'] = splits[1]
df['lastName'] = splits[2] + " " + splits[3]
print "Case 3: First: " + df['firstName'] + " middle: " +df['middleName'] + " last: " + df['lastName']
There is something basic that I'm missing.
if len(name) >= 3: # (assume that user only has one middle name)
firstname = splits[0]
middlename = splits[1]
lastnames = splits[2:] ( catch all last names into a list )
I've been trying to make this work for some time now and I can't seem to get my list to sort out in ascending order. My program asks the user to enter three integers and then outputs results and is supposed to sort the numbers entered from least to greatest. However, whenever I try to sort it, it does not sort it the way I want to do. I've tried several ways of modifying the sort method, but it still does not work. For example, if I enter in 2, 10, and 5 as my three numbers, it will display it as "List: [2, 10, 5]".
import math
print ("")
print ("Welcome to my program!")
print ("")
v1 = input("Enter the first number: ")
print ("")
v2 = input("Enter the second number: ")
print ("")
v3 = input("Enter the third number: ")
print ("")
#tried to sort list here
list1 = [int(v1), int(v2), int(v3)]
sorted(list1, key=int)
sum = int(v1) + int(v2) + int(v3)
product = int(v1) * int(v2) * int(v3)
integer = int(v1)//int(v2)
mod = float(v1) % float(v2)
average = (float(v1) + float(v2) + float(v3))/ 3
star= "*"
print ("------------------")
print (" RESULTS ")
print ("------------------")
print ("")
print ("Sum: " + str(sum))
print ("")
print ("Product: " + str(product))
print ("")
print ("Integer Division: "+ str(integer))
print ("")
print ("Mod: " + str(mod))
print ("")
print ("Maximum Number: ", max(list1))
print ("")
print ("Minimum Number: ", min(list1))
print ("")
print ("Average: " + str(average))
print ("")
#outputs the list
print ("List: " + str(list1))
print ("")
print (v1 + " " + "".join([star] * int(v1)))
print (v2 + " " + "".join([star] * int(v2)))
print (v3 + " " + "".join([star] * int(v3)))
You need to assign to the sorted output:
srted = sorted(list1) # creates a new list
To sort the original list sorting in place use list.sort:
list1.sort() # sorts original list
You don't need to pass a key to sort ints.
sorted returns a value that you must reassign and the key is unnecessary:
list1 = [int(v1), int(v2), int(v3)]
list1 = sorted(list1)
Alternatively, you can call the sort method of the list which directly modifies it without return and reassignment:
list1 = [int(v1), int(v2), int(v3)]
list1.sort()
I am trying to make my own log that makes a string of changed data between object (my old object and my new object) However i keep getting back empty string,
My code:
def log_fields(old_obj, new_obj):
fields = new_obj.__class__._meta.fields
changed_fields = ""
old_data = ""
new_data = ""
# get all changed data
for field in fields:
old_field_data = old_obj.__getattribute__(field.name)
new_field_data = new_obj.__getattribute__(field.name)
if old_field_data != new_field_data:
count =+ 1
# convert changed data to strings
# number + space + data + 5 spaces for next string
changed_fields.join(str(count)).join(" ").join(str(field)).join(" ")
old_data.join(str(count)).join(" ").join(str(old_field_data)).join(" ")
new_data.join(str(count)).join(" ").join(str(new_field_data)).join(" ")
print changed_fields
print old_data
print new_data
I got a feeling something with the string .join combination something is going wrong, cause trying this manually in shell seems to work up to the comparison. Not sure tho hos i should change the string
changed_fields = changed_fields + str(count) + "." + str(field.name) + " "
old_data = old_data + str(count) + "." + str(old_field_data) + " "
new_data = new_data + str(count) + "." + str(new_field_data) + " "
Seems to do the job, so for now, ill keep it at this
I've been working on a small contact importer, and now I'm trying to implement a block that automatically selects the output file format based on the number of contacts to be imported.
However, every time it results in the error:
KeyError: 'q'
I can't figure out for the life of me why this is happening, and I would love any help offered.
My idea of scalability is that the dictionary personDict would be of the format personDict = {nameid:[name,email]}, but nothing works.
Any help is good help,
Thanks
def autoFormat():
while True:
name = input("Enter the person's name \n")
if name == "q":
break
email = input("Enter the person's email \n")
personDict[name] = [name, email]
if len(personDict) <= 10:
keyValue = personDict[name]
for keyValue in personDict:
for key, value in personDict.iteritems():
combined = "BEGIN:VCARD\nVERSION:4.0\n" + "FN:" + name + "\n" + "EMAIL:" + email + "\n" + "END:VCARD"
fileName = name + ".vcl"
people = open(fileName, 'a')
people.write(combined)
people.close()
print("Created file for " + name)
autoFormat()
The main problem is that when the user types "q" your code leaves the while loop
with name keeping "q" as value. So you should remove this useless line:
keyValue = person_dict[name]
Since there is no element with key "q" in your dictionary.
Also in the export part you write in file values different from those you loop with.
Your code becomes:
if len(personDict) <= 10:
for name, email in personDict.values():
combined = "BEGIN:VCARD\nVERSION:4.0\n" + "FN:" + name + "\n" + "EMAIL:" + email + "\n" + "END:VCARD"
fileName = name + ".vcl"
people = open(fileName, 'a')
people.write(combined)
people.close()
print("Created file for " + name)
