[FIXED] elif <= invalid syntax?

Issue

i am currently working on a calculator using pandas, and to determine a variable I have used a nested if statement. But unfortunately, I get an invalid syntax error from the below code.

    if net_option == 'Y':
        if age <= 30:
            desired_net = 0.15
        elif age >= 31 and <= 60:
            desired_net = 0.12
        elif age >= 61 and <= 90:
            desired_net = 0.11
        elif age >= 91 and <= 140:
            desired_net = 0.10
        elif age >= 141 and <= 180:
            desired_net = 0.09
        elif age >= 181 and <= 245:
            desired_net = 0.08
        elif age >= 246 and <= 270:
            desired_net = 0.07
        elif age >= 271 and <= 365:
            desired_net = 0.6
        elif age >= 366 and <= 500:
            desired_net = 0.3
        elif: age >= 501 and <= 700:
            desired_net = 0.0
        elif age > 700:
            desired_net = -0.1
        else:
            desired_net = 0.1
    else:
        desired_net = desired_net

Error message:

elif age >= 31 and <= 60:
                    ^
SyntaxError: invalid syntax

I think I am missing something here as I am pretty sure that <= is a valid syntax.

Has anyone got an idea what may be wrong? Let me know if you would like to see more lines.

Solution

elif age >= 31 and age <= 60:

When using the and operator, you are required to write the variable to compare against again, because each expression before and after and stands on its own.
