I wrote the following program in Python but I got this error please guide me

age= (input("please inter your age:" ))
if age > 40:
    print ("old")
elif 40>age>=30:
    print ("middle-age")    
elif 30>age>=20:
    print ("yong")

TypeError: '>' not supported between instances of 'str' and 'int'

I checked the program several times

the age variable is of string data type. You need to convert it to int before comparing it using operators like this -

age= int(input("please inter your age:" ))
if age > 40:
    print ("old")
elif 40>age>=30:
    print ("middle-age")    
elif 30>age>=20:
    print ("yong")

The int() before the input statement will convert the data entered by the user from string to int type.

while doing comparison change the age type to int, Since you input age with use of input which returns string.

age= (input("please inter your age:" ))
if int(age) > 40:
    print ("old")
elif 40>int(age)>=30:
    print ("middle-age")    
elif 30>int(age)>=20:
    print ("yong")

This gives you the expected output you want

output:

please inter your age:45
old
