Accessing list of dictionaries within a dictionary in python - python-2.7

Question

So lets see how bad i messed this up
This is what is supposed to look like
Students
1 - MICHAEL JORDAN - 13
2 - JOHN ROSALES - 11
3 - MARK GUILLEN - 11
4 - KB TONEL - 7
Instructors
1 - MICHAEL CHOI - 11
2 - MARTIN PURYEAR - 13
How ever the two extra arrays are throwing me for a loop. I called the for loop for the first one thus having students and instructors. Then I called the keys and value. Could some one please look at this and point me in the right direction to fix this mess
users = {
'Students': [
{'first_name': 'Michael', 'last_name' : 'Jordan'},
{'first_name' : 'John', 'last_name' : 'Rosales'},
{'first_name' : 'Mark', 'last_name' : 'Guillen'},
{'first_name' : 'KB', 'last_name' : 'Tonel'}
],
'Instructors': [
{'first_name' : 'Michael', 'last_name' : 'Choi'},
{'first_name' : 'Martin', 'last_name' : 'Puryear'}
]
}
for i in users:
for i in Students:
print ([i['first_name'], i['last_name']] , + len([i['first_name'], i['last_name']
for i in Instructors:
print ([i['first_name'], i['last_name']] , + len([i['first_name'], i['last_name'0]

Answer 1

Basically, you are trying to override the value of i with your loops, you should avoid doing it, also when you just use for i in users: you are iterating only through the keys of dict users, you can use dict.items() or dict.iteritems() to access both key, value pair in the dictionary.
And here is your updated code, just in case.
for usr, info in users.iteritems():
print "{}".format(usr)
for i, _info in enumerate(info, 1):
name = "{first_name} {last_name}".format(**_info).upper()
print "{} - {} - {}".format(i, name, len(name)-1)
I will leave it to you to understand the code and the builtin functions being used in the code.
