Question

May it’s very simple question, but I’m stuck here.
I have variable val as val="mandy", now i want to create a list whose name is the content of val. i.e. “mandy”. so how to define mandy=[] in python.
It’s like “$$” equivalent of PHP.

Answer 1

You can do something like this in Python, but it’s very un-Pythonic to do so (whereas it’s a common PHP idiom as I gather). Don’t use the language in a way it’s not intended to be used.

What you’re trying to do is much better done by using a dictionary, a maximally optimized datatype in Python:

>>> val = "mandy"
>>> mydict = {}
>>> mydict[val] = []
>>> mydict[val].append("Hello")
>>> mydict[val].append("Mandy")
>>> mydict
{'mandy': ['Hello', 'Mandy']}
