Python 如何为列表中的每个项目创建集合？

Question

How can I create sets for every item in my list?

This is my list:

listofstrings = ['sdfasdf', 'sdfaserth', 'wegoiog']

I want it to create sets like this:

set1 = set(), set2=set(), set3=set()

Answer 1

You can create a list of them like this

sets = []
listofstrings=['sdfasdf', 'sdfaserth', 'wegoiog']
for string in listofstrings:
    sets.append(set())

Answer 2

I would use a dictionary to do it(so you can access each set matching the corresponding string).

name_to_set = {}
listofstring = ['sdfasdf', 'sdfaserth', 'wegoiog']
name_to_set = {name: set() for name in listofstring}

so later you can use it as follows:

name_to_set['sdfasdf'].add('x')

Answer 3

You can create as following:

for index, word in enumerate(listofstrings):
    exec("set%d = %s" % (index + 1, set()))

Answer 4

listofstrings=['sdfasdf', 'sdfaserth', 'wegoiog']
l = [set() for se in listofstrings]

Answer 5

As I mentioned, this question is unclear and probably a case of the XY problem . I feel the need to share a solution because so many of the current ones are bizarre at best.

list_of_strs = ['sdfasdf', 'sdfaserth', 'wegoiog']

sets_list = [set() for _ in list_of_strs]

Notice I changed the variable names. In Python, variable names should generally follow the lower_case_with_underscores style.
