如果在python中麻烦 [英] Trouble with if in python

问题描述

嘿刚刚开始学习python并且已经遇到了一些问题
我用if语句创建了一个代码它应该工作但它不起作用
可以有人修复它并告诉我我做错了什么？

Hey just starting to learn python and got some problems already I made a code with an if statement It should work but it isn't working can someone fix it and tell me what I did wrong?

x= raw_input("Enter your name: ")
y= raw_input("Enter your grade: ")
print(y)
if y>=50 and y<=100:
    print("Good input")
else:
     print ("Invaild input")

它始终打印无效输入
谢谢！

It always prints Invalid input thanks!

推荐答案

raw_input（）返回一个字符串但你要比较 x 和 y 包含整数。

raw_input() returns a string but you are comparing x and y with integers.

转 y 比较之前输入一个整数：

Turn y into a integer before comparing:

y = int(y)
if y >= 50 and y <= 100:

您可以通过链接简化比较，让您内联 int（） call：

You can simplify your comparison a little with chaining, letting you inline the int() call:

if 50 <= int(y) <= 100:
