Python : Find out the variable type and determine the type with simple test



Tags : python variable-type type-function

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'>
