how to determine where is list where is not?

Answer 1

You should try with isinstance(variable, list).
I am not really sure what type is a list, but I think it's that one.
But you could always override the "magic method" for isinstance to give the function the behaviour you want

Answer 2

Refine your thought, please. I don't understand what you mean

Answer 3

I mean are there some attribute or function that can be let we know it's a list or not

Answer 4

no : a string also has the square brackets

Answer 5

I totally agree with Amaras A.
simply check, if isinstance(e,list):
if you want to find if it is a list or tuple you can add tuple
if isinstance(e,(list,tuple))

Answer 6

actually your question is good...we can find list by the square bracket [ ]

Answer 7

you can use print type(variable_name)
