当您运行程序并选择某些内容时，它有时不会确认输入。对不起，如果有明显的错误。我还是很陌生。感谢您提前获得所有帮助。 这不是一个主要的问题，但它是一个学校的事情，所以最好我想解决它。

答案 0 :(得分：0)
在所有第一个if语句的末尾，添加一个传递。
答案 1 :(得分：-1)
input已经返回一个字符串，因此使用str再次将其转换为字符串是没有意义的。由于您的输入将是一个数字，请将其转换为整数
# ... rest of your code
inp = input("Enter a numerical option: ")
try:
inp = int(inp)
except:
print(inp, "is not a valid option")
continue # this will skip everything below and go to the next instance of the while loop which will ask the user again for input
# ... rest of your code
关于代码的结构，可以将其拆分为可以调用的较小函数。
def webListings():
print('1: Google')
...
def passGen()
print(...)
...
然后你可以做这样的事情
if user_input1 == 1:
webListings()
else if user_input1 == 2:
passGen()
