Help me understand why this expression evaluates to True!

Question

This is a challenge quiz question that I (obviously) got wrong.

sex = "F"
if (sex == 'M' or 'm'):
print("Male")
else:
print("Female")

The answer is 'Male', which means that (sex == 'M' or 'm') evaluates to True, right?

Why? I can't get my head around this!

That makes sense, thanks!

Answer 2

Seb TheS I still don't understand how the if clause can evaluate to True since sex = "F"

Answer 3

No, you may replace (sex == 'M' or 'm') to (sex == 'M' or sex == 'm'), but there are 3 other ways:
(sex in 'Mm')
(sex.lower() == 'm')
(sex.upper() == 'M')

Anyways (sex == 'M' or 'm') doesn't always work, because it thinks 'm' as a condition, technically it would work like this: (sex == 'M' or bool('m'))
And bool('m') is always True.

Answer 4

The if statement evaluate to true because there is a or. Yes the first comparition is false but second is true as Sed TheS wrote the letter m is considered to be true. See it in this code:https://code.sololearn.com/cDGZRObaNwCi/?ref=app
