执行Python提示《not supported between instances of str and int》

1 n = input()
2 if n>=100:print(int(n)/10)
3 else:print(int(n)*10)

报错内容：

Traceback (most recent call last):File "1.py", line 12, in <module>if n>=100:print(int(n)/10)
TypeError: '>=' not supported between instances of 'str' and 'int'***Repl Closed***

分析：input()返回的数据类型是str，不能直接和整数进行比较，必须先把str换成整数，使用int()方法

因此，将input变量转换为int型即可。

1 n = input()
2 n = int(n)
3 if n>=100:print(int(n)/10)
4 else:print(int(n)*10)

或者：

1 n = int(input("Input a number:"))
2 if n>=100:print(int(n)/10)
3 else:print(int(n)*10)
