Ok lets start with
1.
l = len(names)
for i in range(0,l): ... names[1] ...
Better to do in python as
for n in names: ... n ...
ie use n where you were using names[i]
no need for range, len, indexing etc etc
2.
You are setting (ie assigning) message each time round the loop
Try writing a function that does NO set (assign) NO print
Ok this time let me write it for you
So I write a function called foo, taking an argument called nn
>>> def foo(nn):
... for n in names:
... if n == nn: return True
... return False
...
Note: No input, No output, No file IO and above all No assignment
>>> foo(("nam1","F","Y"))
True
>>> foo(("nam4","F","Y"))
False
Notice my foo takes an argument that is a triplet
You need to change foo to taking name and sex and ignoring the third element
Your homework -- Oui??
