Dear List,
the following comes from Harrington's "Hands-on Python" (section
1.11.8): http://www.cs.luc.edu/~anh/python/hands-on/
<code>
'''Avoiding any error by passing a parameter'''
def main():
x = 3
f(x)
def f(whatever):
print whatever
main()
</code>
I am not quite sure what is going on here. Could you please correct my
line of thought?
1) main() calls the function def main():
2) in function def main(): the actual parameter 3 is given to the
function call f().
3) f() then "jumps" out of function def main(): to call function
def f(whatever):, whose new value, 3, gets printed.
Is this what is going on? I find it difficult to get my head around this
one.
Also: does Python go back to the function call main()'s position after
step 3)? How does that work? Again via def main():???
Cheers for any clarifications,
David
