I want to insert a number and if I put any number other than 4 it will tell me it's wrong, but if it's false it will tell me "gg you win, noob.". However when I insert 4, it tells me it's incorrect.
x = input("Insert a numer: ")

print("incorrect")
x =input("Insert another number: ")
if x == 4:
print("gg you win, noob")
推荐答案
在 Python 3+ 中,input
返回一个字符串,4
不等于 '4'
.您必须修改为:
In Python 3+, input
returns a string, and 4
does not equal '4'
. You will have to amend to:
while x != '4':
或者使用int
,如果输入不是int,小心检查ValueError
.
or alternatively use int
, being careful to check for a ValueError
if the input is not an int.
