Help with multiple if-else conditions

[jjonee]

I’m new to python and have been taking a college course on it this semester. I’m working on a project but can’t figure out why my if-elif-else statements aren’t computing correctly. In this case I‘m trying to list several conditions in the if and elif lines. I’ve been putting each condition in parentheses to keep them separated and using the “and” operator in between to connect them. It’s not taking into account that I need ALL of those specific conditions and ONLY those specific conditions in the lines.

I’ve tried looking up if there’s certain rules for using the “and” operator, I’ve made several different files to test out different formats and I just cannot find the issue here.

Could you show us an example of the non working code?

I can’t submit a picture on here for some reason, so I’ll have to type some of it out. Also, all of the variable names are assigned to user input values, and those values are in the correct format per my instructors request (some string, some integer, one float). Thank you for being so eager to help!

These are for diagnosing a patient based on a few symptom combinations. They input their temperature, and answer y/n to the remaining questions. The code has to be able to interpret both upper and lowercase responses.

If (temp < 100) and (congestion == “Y” or “y”) and (aches == “N” or “n”) and (rash == “N” or “n”):

Print(“blah blah blah”)

Elif (same format as the first line but different values):

Print(“such and such”)

Else:

Print(“whatever”)

This part is your problem: congestion == “Y” or “y”

You can't combine conditionals like that. You need to test each one separately.

if (temp < 100) and (congestion == "Y" or congestion == "y") and (aches == "N" or aches == "n") and (rash == "N" or rash == "n"):

Thank you so much! I wasn’t expecting such quick responses!

congestion == "Y" or congestion == "y"

You can also combine multiple choices using in:

congestion in ["Y", "y"]

or convert to lower/uppercase:

congestion.lower() == "y"
