为列表中的每个项目创建一个空列表

Question

I have a list that came from an excel doc:

["GT", "FSU", "Duke"]

I am trying to make an empty list for each item in this list (to look like this):

GTList = []
FSUList = []
Duke = []

Is there an easy way to go from step 1 to step 2. I need to use loops too because there is a possibility of there being an extra school in the first list. If this is the case, there needs to be a corresponding empty list for that new school. Please let me know what advice you have.

Answer 1

I would use a dictionary comprehension:

schools = ["GT", "FSU", "Duke", "Stanford"]

schools_list = {school: [] for school in schools}

>>> schools_list
{'Duke': [], 'FSU': [], 'GT': [], 'Stanford': []}

schools_list['Stanford'].append('sucks')
>>> schools_list['Stanford']
['sucks']

Answer 2

I answered similar question earlier today. Try this:

a = ["GT", "FSU", "Duke"]

for i in a:
    locals()[i] = []

print GT, FSU, Duke

Output:

[ ] [ ] [ ]
