I was wondering about the scope of the variable a in the following Python snippet,
# ============================
def get_plotter():
def get_a():
return a
a = 3.14
return get_a
# ============================
if __name__ == '__main__':
f = get_plotter()
print f()
# ============================
The output is 3.14, but looking at the code I would have expected a to go out of scope as soon as get_plotter() terminates, effectively leaving an undefined something.
Is it just volatile memory contents that are printed here? What's going on?
