Python : Find out the variable type and determine the type with simple test
Couple of ways to determine or find out the type of a variable or object in Python. Listing down the methods here for future reference :
Use type(variable) method
num_array = [0,1,2,3]
type(num_array)
> <class 'list'>
t = ()
type(t)
> <class 'tuple'>
Sometimes we are not sure what the variable or object type is before performing operation on the variable. We can test it by type(variable) is
. For example :
type(num_array) is list
>True
type(num_array) is str
>False
or with isinstance()
function :
isinstance(num_array, list)
>True
isinstance(num_array, str)
>False
By the way, you can do this way as well if you prefer. With __class__
example :
num_array.__class__
> <class 'list'>
