python - 如何在 Python 中用单个字符/单词替换多个不同的单词？

Question

注意：不使用链接替换方法（或）循环 for 循环（或）列表理解中的字符

input_string = "the was is characters needs to replaced by empty spaces"

input_string.replace("the","").replace("was","").replace("is","").strip()

输出：'字符需要替换为空格'

有没有直接的方法可以做到这一点？

您可以使用 python 正则表达式模块（re.sub）用单个字符替换多个字符：

input_string = "the was is characters needs to replaced by empty spaces"

import re
re.sub("the|was|is","",input_string).strip()

'字符需要替换为空格'
