Hi, What is the appropriate definition for the following behavior in Python 2.7 (see code below). Both functions have assignment in it (like "x = ") so I assume, that x is a local variable in both functions. Also I thought this rule doesn't depend on WHERE in this function we find the assignment.
But in both functions x becomes local variable only AFTER assignment, so in f2 x[1] = 99 changes the global varialble (btw, x[3] = 99 doesn't). def f1(x): x = [44] + x[1:] x[1] = 99 def f2(x): x[1] = 99 x = [44] + x[1:] x[3] = 99 t = [1,2,3,4,5,6,7] f1(t) print t # [1, 2, 3, 4, 5, 6, 7] t = [1,2,3,4,5,6,7] f2(t) print t # [1, 99, 3, 4, 5, 6, 7] Thank you.
