What is Programming?

It is the fastest way to tell the computer what to do. E.g. A calculator.

In other words, we can say that computer programming is the process of writing code to facilitate specific actions in a computer, application or software program, and instructs them on how to perform. 

Programming Languages:

Python, C, C++, Java, Ruby etc.

What is Python?

It is:

  • An interpreted language.
  • It is dynamically typed.
  • A case-sensitive language.
  • Supports object-oriented programming language.
  • Gouido Van Rossum first started working on Python in 1991.

Example:
```
print("Hello World", 7)

print(5)
```

Output:
```
Hello World, 7
5
```

Features of python:

  • Simple and easy programming language.
  • Platform independent (means can work on any platform).
  • An open-source language.
  • Has big-library support. Some popular libraries are NumPy, TensorFlow, OpenCV etc.

Uses of Python:

It can be used in:

  • Data Visualization to create plots and graphical representations.
  • Helps in Data Analytics to analyze and understand raw data insights and trends.
  • AI and Machine Learning to learn from past data without hardcoding. 
  • Web applications.
  • Handle databases.
  • To perform complex mathematical analysis with data in business and accounting.
