如何在列表元素之前和之后放置一个空格？

Question

How I can put one space before and after list elements?

For example list=['A','B','C']

I want

list=[' A ',' B ',' C ']

Answer 1

#Simple way
list = [' '+x+' ' for x in list] 

#F-strings way
lits = [f' {x} ' for x in list]

Answer 2

Use f-strings or formatted string literals and list comprehension :

lst = [f' {x} ' for x in lst]

Answer 3

Didnt you just answer the question yourself

by using:

list = [' A ',' B ',' C ']

The code already works when you print

print(list[0])

it will print 'A' with a space before and after it

In order to verify this see the difference by printing the first charectors of the first list and second list

first list = list = ['A', 'B', 'C'] second list = list = [' A ', ' B ', ' C ']
