我試圖從python中的字符串中移除問號,我想知道最有效的方法是什麼。我假設搜索每個單詞?不是最好的方法。只是爲了澄清,我期待改變這種從字符串中移除問號

"What is your name?" 

這個

"what is your name" 
+0

"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

replace()是簡單而有效:

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

在我謙卑的意見y你應該看看內置的string.replace()方法。

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