python-多种可能性的“ if in”语句

Question

I want to check if a question mark or a dot are in the last position of a word. So doing something like:

if ".","?" in word[-1]:

Or:

if [".","?"] in word[-1]:

Result in an invalid syntax. What is the right way to do this? (preferably without regex)

Answer 1

对于这种特殊情况，您要检查结尾：

if word.endswith(('.','?')):

Answer 2

You got the order backwards.

if word[-1] in ".?":

Refer to the in operator in the documentation
