What data types are available in Python?

Python has several basic data types:

• Numbers: int (integers), float (floating-point numbers), complex (complex numbers).
• Strings (str): sequences of characters.
• Boolean values (bool): True and False.
• Lists (list): ordered mutable collections.
• Tuples (tuple): ordered immutable collections.
• Sets (set): unordered collections of unique elements.
• Dictionaries (dict): collections of key-value pairs.
• NoneType: the type of the None object, which indicates the absence of a value.

Example usage:

x = 10          # int
pi = 3.14       # float
name = "Ivan"  # str
flag = True     # bool
lst = [1, 2, 3] # list
tpl = (4, 5)    # tuple
st = {1, 2, 3}  # set
d = {"a": 1}   # dict
n = None        # NoneType
