python - how to append item to a global list from within a procedure -

i syntax error when this:

p = [] def proc(n):     in range(0,n):         c =         global p.append(c)

just change following:

def proc(n):     in range(0,n):         c =         p.append(c)

the global statement can used @ top of function, , necessary when assigning global variable. if modifying mutable object not need used.

here example of correct usage:

n = 0 def set_n(i):     global n     n =

without global statement in above function create local variable in function instead of modifying value of global variable.
