I'm doing a small task in Python. I have to categorizes age into six different categories, based on the age ranges specified in the question. If the age is less than 18, the code prints "Category: Under 18". If the age is between 18 and 24, the code prints "Category: 18-24", and so on.

Here's my code:

Age_Group = [18,24,34,44,54,64]


if Age_Group < 18:
    print("Category: Under 18")

elif Age_Group  >= 18 and Age_Group <= 24:
    print("Category: 18-24")

elif Age_Group  >= 25 and Age_Group  <= 34:
    print("Category: 25-34")

elif Age_Group  >= 35 and Age_Group  <= 44:
    print("Category: 35-44")

elif Age_Group  >= 45 and Age_Group  <= 54:
    print("Category: 45-54")

elif Age_Group  >= 55:
    print("Category: 55 and over")

When I executed the code, I got 'TypeError' message:

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

      2 
      3 
----> 4 if Age_Group < 18:
      5     print("Category: Under 18")
      6 

TypeError: '<' not supported between instances of 'list' and 'int'

Can anyone help me with this?

CodePudding user response：

You need to access each element of the list and perform the comparison, instead of using <=> operators between list and integer value:

Age_Group = [18,24,34,44,54,64]

for i in Age_Group:
    print(f"Age {i}")
    if i < 18:
        print("Category: Under 18")
    
    elif i  >= 18 and i <= 24:
        print("Category: 18-24")
    
    elif i  >= 25 and i  <= 34:
        print("Category: 25-34")
    
    elif i  >= 35 and i  <= 44:
        print("Category: 35-44")
    
    elif i  >= 45 and i  <= 54:
        print("Category: 45-54")
    
    elif i  >= 55:
        print("Category: 55 and over")

Output:

Age 18
Category: 18-24
Age 24
Category: 18-24
Age 34
Category: 25-34
Age 44
Category: 35-44
Age 54
Category: 45-54
Age 64
Category: 55 and over
