从Python列表中的项创建新的空列表？

Question

my_list = ['c1','c2','c3']

反正是否有基于列表中的项目创建一定数量的新列表？

结果将是:

c1 = []
c2 = []
c3 = []

Answer 1

你可以这样做globals():

>>> my_list = ['c1','c2','c3']
>>> for x in my_list:
...     globals()[x] = []
...     
>>> c1
[]
>>> c2
[]
>>> c3
[]

但最好在这里使用dict:

>>> dic = {item : []  for item in my_list}
>>> dic
{'c2': [], 'c3': [], 'c1': []}
