Python Built-In Datatypes

In Python most common buit-in types are numeric, sequences & mappings(key-pair).

Data Types

Here are the list of Python buit-in types:

Numeric Types

  • int
  • float
  • complex

Sequence Types

  • list
  • tuple
  • range
  • str

Binary Sequence Types

  • bytes
  • bytearray

Mapping (HashMap Key-Pair)

  • dict

Set Types

  • set

Other Built-In Types

  • bool
  • None
  • ellipsis
  • type

Using Python’s built-in function type() you can check what type of object is assigned to a variable.

#Example: Variable declaration python

my_str = "John"                         # String
my_bytstr = b"John"                     # Bytes
my_int = 50                             # Integer
my_float = 150.50                       # Float
my_list = [1,2,3]                       # List
my_dict = {1:'One', 2:'Two', 3:'Three'} # Dictionary
my_tuple = (1,2,3)                      # Tuple
my_set = {1,2,3}                        # Set
my_bool = True                          # Boolean
my_none = None                          # NoneType

print(type(my_str))
print(type(my_bytstr))
print(type(my_int))
print(type(my_float))
print(type(my_list))
print(type(my_dict))
print(type(my_tuple))
print(type(my_set))
print(type(my_bool))
print(type(my_none))

Output:

<class 'str'>
<class 'bytes'>
<class 'int'>
<class 'float'>
<class 'list'>
<class 'dict'>
<class 'tuple'>
<class 'set'>
<class 'bool'>
<class 'NoneType'>
