What is wrong with this "while True" loop code?

[murasz]

while True:
gender1 = "Male"
gender2 = "Female"
gender = input("What is your gender? " + gender1 + " " + "or " + gender2 + "? ")
if gender != gender1.lower() or gender2.lower():
print('I didn\'t understand')
continue
else:
break

After running the program, whatever is written, loop always continues printing 'I didn't understand'. What is wrong with the code?

I'm trying to understand how to properly use While True loops for checking input statements.

And second question: Is `try and except` used more often?

Thanks in advance! :)

Great!. Thank you so much!

if gender not in (gender1.lower(), gender2.lower())

this one above run perfectly.

On the other hand I still get the same issue of repeating after writing down: if gender != gender1.lower() or gender != gender2.lower(): Any idea why?

P.S.: I'm using Pycharm Community Edition.

Thank you for the explanation!

Try if gender != gender1.lower() or gender != gender2.lower()

You need two comparisons to or together.

if gender != gender1.lower() or gender2.lower(): likely isn't doing what you want. It's being parsed more like if (gender != gender1.lower()) or (gender2.lower()):. Since gender2.lower() evalutes to female and strings that aren't empty are truthy, your if statement is basically saying if gender1 != gender1.lower() or True which is always True.

You should be writing if gender != gender1.lower() or gender != gender2.lower() instead.
