如何在python中合并两个字符串？ [英] How to merge two strings in python?

问题描述

我需要将字符串合并在一起以创建一个字符串。例如，需要组合的 hello字符串为：
[H ----]，[-E ---]，[-LL-]和[---- O]

I need to merge strings together to create one string. For example the strings for "hello" that need to be combined are: [H----], [-E---], [--LL-], and [----O]

这是我必须使字母首位显示的当前代码。

This is the current code I have to make the letters appear in the first place.

display_string = "[" + "".join([x if x == letter else "-" for x in word]) + "]"

我该如何制作诸如
之类的字符串[H ----]，[HE ---]，[HELL-]，最后[HELLO]？

How would I go about making strings such as [H----], [HE---], [HELL-], and finally [HELLO]?

推荐答案

s = "[H----], [-E---], [--LL-],  [----O]"

print(''.join(re.findall(r'\w', s)))

HELLO
