Python supports several built-in data types, including: Numeric Types: Integer (int): Whole numbers without a fractional component. Floating-point (float): Numbers with a fractional component. Complex (complex): Numbers with a real and imaginary part. Sequence Types: String (str): A sequence of characters. List (list): An ordered collection of items. Tuple (tuple): An ordered, immutable collection of items. Mapping Type: Dictionary (dict): A collection of key-value pairs. Set Types: Set (set): An unordered collection of unique elements. Frozen set (frozenset): An immutable version of a set. Boolean Type: Boolean (bool): Represents either True or False. Binary Types: Bytes (bytes): A sequence of bytes. Bytearray (bytearray): A mutable sequence of bytes. These are the main built-in data types in Python. Additionally, Python also allows you to define and work with custom data types using classes and objects. Here are some examples of each data type: Numeric Types: # Integer x = 10 # Float...

Python Variables In Python, variables are used to store data values. A variable can hold different types of data, such as numbers, strings, or booleans. Here's an example of how to create and use variables in Python: # Integer variable num1 = 5 num2 = 10 sum = num1 + num2 print(sum) # Output: 15 # String variable name = "John" print("My name is " + name) # Output: My name is John # Boolean variable is_sunny = True if is_sunny: print("It's a sunny day!") # Output: It's a sunny day! else: print("It's a cloudy day.") In the above example, we first create two integer variables num1 and num2, then we create a variable called sum which holds the sum of num1 and num2. We then print the value of sum using the print() function. Next, we create a string variable name and concatenate it with a string literal using the + operator. Finally, we create a boolean variable is sunny and use it in an if-else statement to print whether it...
Python Indentation In Python, indentation plays a crucial role in determining the scope and organization of code blocks. Python uses whitespace indentation to delimit blocks of code, rather than curly braces ({}) or similar constructs used in other programming languages. Here are some basic rules to keep in mind when it comes to indentation in Python: Use consistent indentation throughout your code. Indent your code with four spaces (not tabs). Indentation level should be consistent for all statements within a block of code. Indentation should be used to indicate the scope of a block of code, such as within a function definition, loop or conditional statement. Be careful not to mix tabs and spaces in your code, as this can cause indentation errors. Here are a few examples to illustrate how indentation works in Python: Example 1: If-else statement In the correct example, the if and else statements are indented to the same level to indicate they are part of the same block of code. ...
