将标点符号更改为空格（空格字符）

Question

到目前为止，它已经删除了标点符号，但是我不知道如何使它添加一个空格，而不是仅仅删除标点符号。 目前我有：

punctuation = "!\"#$%&()*+,-./:;<=>?@[\\]^_`{|}~"
def remove_punct(theStr):
    theStr_sans_punct = ""
    for letter in theStr:
        if letter not in punctuation:
            theStr_sans_punct = theStr_sans_punct + letter
    return theStr_sans_punct

它位于交互式教科书中，因此它将自动在其站点上进行测试。

通过在代码中添加else代码：

punctuation = "!\"#$%&()*+,-./:;<=>?@[\\]^_`{|}~"
def remove_punct(theStr):
    theStr_sans_punct = ""
    for letter in theStr:
        if letter not in punctuation:
            theStr_sans_punct = theStr_sans_punct + letter
        else:
            theStr_sans_punct = theStr_sans_punct + " "
return theStr_sans_punct
