从字符串中删除问号

Question

我正在尝试从python中的字符串中删除问号，我想知道最有效的方法是什么。我假设搜索每个单词？不是最好的方法。只是为了澄清，我希望改变这个

"What is your name?"

到这个

"what is your name"

Answer 1

"What is your name?".replace("?","") #this is the most clear
#or
filter(lambda x:x!= "?","What is your name?")
#or
"".join(x for x in "What is your name?" if x != "?")
#or
"What is your name?".translate(None,"?") #this is my favorite

还有更多

Answer 2

replace()简单而有效：

>>> "What is your name?".replace("?", "")
'What is your name'

Answer 3

在我看来，你应该看一下内置的string.replace（）方法。

result = "What is your name?".replace('?', '')
