combining if statement with conditional statement in Python 3.x : when "if" is combined with "or", which one Python prioritise first:
for example:
    if a == b or c
is it (a == b) or c  or is it a == (b or c)
I assume the correct logical form should be the former one but I accidentally used:
    if gender == "m' or "M" 
and to my surprise it did not generate any errors and did the purpose.
