如何在 python 的字符串中查找关键字？

Question

我有一个 Python 程序，我需要在其中找到用户键入的关键字，例如字符串中可能包含其他未知单词的单词“schedule”。 到目前为止，我有这个，但它总是说favorite的是True.

option = input("Would you like to start your schedule or open a favorite site? ")
schedule = False
favorite = False

if "schedule" in option:
    schedule = True
elif "favorite" or "site" in option:
    favorite = True
else:
    print("Please pick an option")

print(schedule)
print(favorite)

Answer 1

这是人们常犯的错误。

import webbrowser

webpage = "https://classroom.google.com/u/1/h"
option = input("Would you like to start your schedule or open a favorite site? ")
schedule = False
favorite = False

if "schedule" in option:
    schedule = True
elif "favorite" in option or "site" in option:
    favorite = True
else:
    print("Please pick an option")

print(schedule)
print(favorite)

你搞砸了第二个 if 语句。 你这样做了

elif "favorite" or "site" in option:

而是这样做

elif "favorite" in option or "site" in option:
