How to turn a list of integers to integers only (python)

Question

在不使用循环的情况下，有没有办法将诸如 [88, 88, 88] 之类的整数字符串转换为 88 88 88 （仅用空格分隔的整数）？

Answer 1

You contradict yourself: at one point, you say you have a list of integers, and later, you say you have a string "[88, 88, 88]". Here's how to make both into your desired string.

In case of list:

string = " ".join(list)

Should suffice. The string method join() returns a string with all the elements in a list, separated by another string (in this case, " ").

In case of string:

import re
new_string = re.sub('[\[\]\,]', '', old_string)

Good ol' regex comes in handy.
