Hello,
If I have a class that has some member functions, and all the functions
define a local variable of the same name (but different type), is there
some way to use getattr/setattr to access the local variables specific
to a given function?
Obviously there's no need to do this for the small test case below,
but I'm working on a bigger code where being able to loop through
variables that are local to func2 would come in handy.
For example:
class A(object):
def __init__(self):
pass
def func1(self):
a = {"A": 1}
b = {"B": 2}
def func2(self):
a = [1]
b = [2]
for attr in ("a", "b"):
var = getattr(self, attr) ! What do I put in place of self
var.append(100) ! to access vars "a" and "b" that
! are local to this function?
You can get the local names of a function using locals():
class A(object):
def __init__(self):
pass
def func1(self):
a = {"A": 1}
b = {"B": 2}
def func2(self):
a = [1]
b = [2]
for name in ("a", "b"):
var = locals()[name]
var.append(100)
BTW, in Python they're called "methods". (C++ calls them "member
functions", but Python isn't C++!)
