In Python 2, how do I write to variable in the parent scope?

Question

I have the following code inside a function:

stored_blocks = {}
def replace_blocks(m):
    block = m.group(0)
    block_hash = sha1(block)
    stored_blocks[

(see below for the edited answer)

You can use something like:

def convert_variables(m):
    name = m.group(1)
    convert_variables.num_converted += 1
    return '<%%= %s %%>' % name

convert_variables.num_converted = 0

This way, num_converted works as a C-like "static" variable of the convert_variable method

def convert_variables(m):
    name = m.group(1)
    convert_variables.num_converted = convert_variables.__dict__.get("num_converted", 0) + 1
    return '<%%= %s %%>' % name

This way, you don't need to initialize the counter in the main procedure.
