What is Python?

• Python is a computer language used in various applications It was introduced by Guido van Rossum and is an open-source high-level and object-oriented language

• Python consists of vast libraries and frameworks like Django, Flask, TensorFlow, PyTorch, Pandas, etc.

How to install Python

For Windows:

Click here to download Python on the Windows operating system

For Linux:

Open Terminal and type the below command to install the python

sudo apt-get update
sudo apt install python3

Task1:

1. Install Python in your respective OS, and check the version.

    python3 --version
   

2. Read about different Data Types in Python.

   1. Numeric Types:

      • int: Represents integers, such as 1, -5, or 1000.

      • float: Represents floating-point numbers, which are numbers with a decimal point, like 3.14 or -0.5.

      • complex: Represents complex numbers in the form a + bj, where a and b are floats, and j represents the square root of -1 (e.g., 3 + 2j).

   2. Sequence Types:

      • str: Represents strings of characters, like "Hello, World!" or 'Python'.

      • list: Represents ordered, mutable (changeable) sequences of objects. Lists are created using square brackets, e.g., [1, 2, 3].

      • tuple: Represents ordered, immutable (unchangeable) sequences of objects. Tuples are created using parentheses, e.g., (1, 2, 3).

   3. Mapping Type:

      • dict: Represents a dictionary, which is an unordered collection of key-value pairs. Dictionaries are created using curly braces with key-value pairs, e.g., {'name': 'Alice', 'age': 30}.

   4. Set Types:

      • set: Represents an unordered collection of unique elements. Sets are created using curly braces or the set() constructor, e.g., {1, 2, 3} or set([1, 2, 2, 3]).

      • frozenset: Similar to a set but is immutable. Once created, you cannot modify its contents.

   5. Boolean Type:

      • bool: Represents a Boolean value, which can be either True or False. It's often used for conditional statements and logical operations.

   6. None Type:

      • None: Represents the absence of a value. It is often used to indicate the absence of a return value in functions or methods.

   7. Binary Types:

      • bytes: Represents a sequence of bytes, similar to a string but immutable. It's often used for working with binary data.

      • bytearray: Similar to bytes but mutable.

   8. Iterator Types:

      • iterable: Represents any object capable of returning its elements one at a time. Common iterable types include lists, tuples, dictionaries, and strings.

      • iterator: Represents an object that implements the iterator protocol, allowing you to loop over its elements using a for loop or the next() function.

   9. Custom Classes:

      • Python also allows you to define your own custom data types using classes. You can create objects with attributes and methods to represent complex data structures.
