Day 2 : Python Basics
Understand and learn the basics the python programming language.
Day 2 Quiz: Please take in order to gauge your understanding of Day 1 concepts
Based on the questions you get incorrect, please review the material from Day 1 to ensure your understanding before proceeding
Programming Language
-
As we know, to communicate with a person, we need a specific language, similarly to communicate with computers, programmers also need a language is called Programming language.
-
Before learning the programming language, let's understand what is language?
What is Language?
-
Language is a mode of communication that is used to share ideas, opinions with each other. For example, if we want to teach someone, we need a language that is understandable by both communicators.
What is a Programming Language?
-
A programming language is a computer language that is used by programmers (developers) to communicate with computers. It is a set of instructions written in any specific language ( C, C++, Java, Python) to perform a specific task.
-
A programming language is mainly used to develop desktop applications, websites, and mobile applications.
Python is one of the most widely used user-friendly programming languages. It is an open-source and easy to learn programming language developed in the 1990s. It is mostly used in Machine learning, Artificial intelligence, Big Data, GUI based desktop applications, and Robotics.
Advantages
-
Python is easy to read, easy to understand, and easy to write.
-
It integrates with other programming languages like C, C++, and Java.
-
Python executes code line-by-line, so it is easy for the programmer to find the error that occurred in the code.
-
Python is platform-independent means you can write code once and run it anywhere.
Disadvantages
-
Python is not suitable for developing mobile applications and games.
-
Python works with the interpreter. That's why it is slower than other programming languages like C and C++.
Python Programming Introduction
The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers).
