im having trouble with my python code and the if-then thing-CodePudding

ok the problem is, is that im trying to make a if then for a character sheet maker when it askes for gender this is my code

gender = input('what gender would you like your character to be? ').capitalize()
if gender == 'Male' or 'Guy' or 'man' or 'Boy' or 'M':
gender = 'He'
elif gender == 'Female' or 'Woman' or 'Girl' or 'Lady' or 'F':
gender = 'She'
else:
gender == ()
gender = 'They'

problem is...it only gives back "he" no matter the answer....what am i getting wrong? thing is...this is what ive learned via w3 and youtube

i have tried different ways to code it...i have even tried making it a def function but nothing seems to work...

The issue is that your or operators are not doing what you think. Consider your if statement:

if gender == 'Male' or 'Guy' or 'man' or 'Boy' or 'M':

It is interpreted as:

if (gender == 'Male') or ('Guy') or ('man') or ('Boy') or ('M'):

So every time it is returning True because the string Guy is interpreted as True:

>>> if 'Guy': print("yes")
yes

What you need is the in operator:

if gender in ['Male', 'Guy', 'man', 'Boy', 'M']:

However guy will return They so you may want to convert gender to lowercase:

if gender.lower() in ['male', 'guy', 'man', 'boy', 'm']

The problem is when you are not using a comparison it is treated as True or False. Empty variables, 0, empty arrays, False are Treated as False in python.

if gender == 'Male' or 'Guy' or 'man' or 'Boy' or 'M':

In this case your are only comparing gender with the male. And

'Guy' or 'man' or 'Boy' or 'M':

are Treated as bools(True). Therefore gender is always assigned to the 'He' and pass without going to elif as There is always something True in If statement.

There are two ways you can fix this.

gender = input('what gender would you like your character to be? ').capitalize()

if gender == 'Male' or gender=='Guy' or gender=='man' or gender=='Boy' or gender=='M':
    gender = 'He'

elif gender == 'Female' or gender=='Woman' or gender=='Girl' or gender=='Lady' or gender=='F':
    gender = 'She'

else:
    gender = 'They'

Which is very inconvenient. Second method is,

gender = input('what gender would you like your character to be? ').capitalize()

if gender in ['Male','Guy','man', 'Boy', 'M']:
    gender = 'He'
elif gender in ['Female', 'Woman', 'Girl', 'Lady', 'F'] :
    gender = 'She'
else:
    gender = 'They'
