如何在字符串Python中的每个逗号前插入问号？ [已关闭]

提问者：小点点

如何用Python在字符串中的每个逗号前插入问号？例如，刺痛将是

string = 'the, quick, brown, fox, jumps, over, the lazy, dog'
print(string)

所需的输出为

the?, quick?, brown?, fox?, jumps?, over?, the?, lazy?, dog

你可以这样做

string.replace(",", "?,")
print(string)

将输出为:

'the?, quick?, brown?, fox?, jumps?, over?, the?, lazy?, dog'

请尝试以下操作:

string_list = string.split(", ")

new_list = []
for string in string_list:
    new_list.append(string + "?")
final_string = ", ".join(new_list)

或者这样:new_string=string.replace（“，”，“？，”）
