How to make a list to split into each element and make a sublist

Question

If I have this list,

list01 = ['GAGGT','TCCGT','ABECF']

I want to make each element in the list to split, but still remain in the same box of list. Like this:

listalt = [['G','A','G','G','T'],['T','C','C','G','T'],['A','B','E','C','F']] 

Answer 1

listalt = [list(i) for i in list01]

这是一个列表理解 ，并利用list可以采用可迭代（如字符串）并将其转换为list事实

Answer 2

You can use this :

final_list=[]
for item in list01:
    final_list.append(list(item))

print(final_list)

which is same as :

print([list(item) for item in list01])
