Assignment question: Write a function called list_max that takes a list named a as input and finds and returns its largest element. Don't use the built-in max function.
The function is written like this to start:
def list_max(a):
# What I have so far is:
for num in a:
if num > a:
return num
But this is returning back to me as incorrect. Is there something I am missing or not doing?
