Exploring Python's Data Types

Python offers a rich variety of data types, which are essential for programming and organizing information. Understanding these data types is crucial for writing efficient and reliable code. Here, we'll cover some of the most common Python data types, along with examples and use cases.

Numeric Data Types

Python supports integers (int), floating point numbers (float), and complex numbers (complex).

x = 5                   # Integer (int)
y = 3.14                # Floating-point number (float)
z = 1 + 2j             # Complex number (complex)
print("Type of x: ", type(x))
print("Type of y: ", type(y))
print("Type of z: ", type(z))

String Data Type

Strings in Python are collections of characters, enclosed in single quotes, double quotes, or triple quotes.

s1 = "Welcome to the Geeks World"  # String (str)
s2 = '''This is a multiline
string'''  # Multiline string (str)
print("Initial String: ", s1)
print("First character of String: ", s1)
print("Last character of String: ", s1[-1])
print("Type of s1: ", type(s1))

Sequence Data Types

Sequence data types include lists, tuples, and ranges.

lst = [1, 2, 3]  # List (list)
tup = (1, 2, 3)  # Tuple (tuple)
print("Type of lst: ", type(lst))
print("Type of tup: ", type(tup))

Binary Data Type

Python's binary data type includes bytes, bytearrays, and memoryviews.

bytes_obj = b'raw_bytes_data'  # Bytes (bytes)
bytearray_obj = bytearray(5)  # Bytearray (bytearray)
print("Type of bytes_obj: ", type(bytes_obj))
print("Type of bytearray_obj: ", type(bytearray_obj))

Mapping Data Type

Python's mapping data type is the dictionary (dict).

d = {'first': 1, 'second': 2}  # Dictionary (dict)
print("Type of d: ", type(d))

Set Data Type

Python's set data type is used for unordered collections of unique elements.

s1 = {1, 2, 3}  # Set (set)
s2 = frozenset({1, 2, 3})  # Frozenset (frozenset)
print("Type of s1: ", type(s1))
print("Type of s2: ", type(s2))

Boolean Data Type

Python's boolean data type has two built-in values, True and False.

b = True  # Boolean (bool)
print("Type of b: ", type(b))

None Data Type

Python's None data type is a special singleton object, used when a variable is intentionally left undefined.

none_obj = None  # None (NoneType)
print("Type of none_obj: ", type(none_obj))

Understanding data types in Python is the foundation for writing efficient and reliable code. This knowledge empowers developers to choose the most appropriate data type, optimize memory usage, and avoid errors or unexpected behavior.
