New submission from Demur Rumed <junkm...@hotmail.com>:
A=[1,2,3]
def f(x):
A+=x,
This throws an error. The solution: state "global a". I find it odd that
augmented assignment should be viewed the same as assignment in descerning
local variables. This patch repairs such to maintain a as a variable of the
global namespace
Some might find the following an issue
def f(x):
if x:
A+=4,
else:
A=[3]
print("f",x,A)
def g(x):
if not x:
A=[3]
else:
A+=4,
print("g",x,A)
In f, A is a global variable. In g, A is a local variable. Thus g(1) throws
UnboundLocalError while f(1) appends 4 to A
