Re: Calling a method with a variable name
May I be the first to say "Doh!"
Problem solved, many thanks to both Carsten and Diez!

At the point you marked "HERE", you've already found the method, and you
have determined that it is callable. You just need to call it. Like
this: method().

You are almost there. Why don't you do
if callable(method):
method()
?

Calling a method with a variable name
Hi All,
I'm collating a bunch of my utility scripts into one, creating a
single script to which I will symbolic link multiple times. This way
I only have to write code for error checking, output-formatting etc a
single time.
So, I have
~/bin/foo -> ~/Code/python/mother_of_all_utility_scripts.py
~/bin/bar -> ~/Code/python/mother_of_all_utility_scripts.py
~/bin/baz -> ~/Code/python/mother_of_all_utility_scripts.py
I would like "bar" to run the bar method (and so on).
-
class Statistic()
def __init__(self):
pass
def foo(self):
return "foo!"
def bar(self):
return "bar!"
#... and so on...
def main():
stats_obj = Statistic()
name = re.sub("[^A-Za-z]", "", sys.argv[0])
method = getattr(stats_obj, name, None)
if callable(method):
stats_obj.name() #
