1)Python Introduction:

Python is a popular programming language. It was discovered by Guido van Rossum in 1991.

Python Used for:

1)web development (server-side)

2)software development

3)Python can connect to database systems. It can also read and modify files.

4)Python can be used to handle big data and perform complex mathematics.

2)Python Features:

Easy to learn: 

Python has simple structure, and clear syntax and easy to learn.

Expressive Language:

Python can perform complex tasks using a few lines of code. A simple example, the hello world program you simply type print("Hello"). It will take only one line to execute, while Java or C takes multiple lines.

Interpreted Language:

Python is an interpreted language where interpreter reads the code line by line. Programming languages such as C, C++ where the compiler first compiles the code and then runs the code.

Free and Open Source:

Python is freely available for everyone. It is freely available on its official website www.python.org. It has a large community across the world that is dedicatedly working towards make new python modules and functions. 

Object-Oriented Language:

Python supports object-oriented language and concepts of classes and objects come into existence. It supports inheritance, polymorphism, and encapsulation, etc. The object-oriented procedure helps to programmer to write reusable code and develop applications in less code.

GUI Programming Support:

Graphical User Interface is used for the developing Desktop application. Tkinter, Kivy are the libraries which are used for developing the web application.

3)Career with Python:

There are numerous exciting career paths available for individuals skilled in Python. Here are some of the options:

1. Python Developer
2. Machine Learning Engineer
3. Data Scientist
4. Data Analyst
5. Data Engineer
6. DevOps Engineer
7. Software Engineer
8. Game Developer
9. Web Developer
10. Full-Stack Developer

4)Python Syntax:

Python is known for its clean and easy-to-understand syntax, which contributes to its popularity among developers.

#Basic Syntax
print("Hello World")

#output
Hello World

Python Indentation:

1)Indentation refers to the spaces at the beginning of a code line.

2)Where in other programming languages the indentation in code is for readability only, the indentation in Python is very important.

3)Python uses indentation to indicate a block of code.

if 10 > 5:
    print("YES")
else:
    print("NO")

Python will give you an error if you skip the indentation:

if 10 > 5:
print("YES")

Indentation Error:

File "myfile.py", line 2
    print("YES")
    ^
IndentationError: expected an indented block after 'if' statement on line 1

NOTE:

The indentation in Python is very important.

5)Python Install:

Python IDLE:

Python IDLE (Integrated Development and Learning Environment) is an interactive development environment that comes bundled with the Python programming language. It provides a convenient way to write, execute, and debug Python code.

Uses:

1. Writing and Executing Code
2. Interactive Shell
3. Debugging
4. Code Completion and Syntax Highlighting
5. Access to Python Documentation
6. Creating Python Modules
