Answer 2

try this:

if sex == 'M' or sex == 'm':

or this:

if sex in ['M', 'm']:

Answer 3

as the rest of the guys/ladies said your code did not work because the IF statement structure. it should be
if sex == ‘m’ or sex == ‘M’.

one of the comentators indicated that you should use ‘else’ instead of ‘elif’. I am not very sure about this. if you use ‘else’ instead of ‘elif’ and the user input a ‘T’ for example or any other letter else will return a “Hello Ms. .......” defeating the purpose of the code.

if you want to use else instead of elif, I would use ‘try’ and ‘except’ loop on the input of the ‘sex’ to make sure that the user only input M,m,F,f

good luck!

Answer 4
