Lists in Python

What is a List?

• The list is one of the most common collection datatypes in Python which is ordered and mutable (changeable).

• It is used to store a group of an element together in a sequence.

• A list can store both homogenous and heterogeneous elements i.e., a single list may contain data types like integers, floats, strings as well as objects.

• Individual value in a list is called an element.

• These elements will be stored in a contiguous memory location.

• For Ex:
• Number1 = 10, 
• Number2 = 20, 
• Number3 = 30, 
• Number4 = 40 

• These individual variables can be represented in a list as

• Number_list = [ 10, 20, 30, 40 ]

Functions in Python basics

Functions In python:

• Set of instructions to perform a specific task.
• Below is the syntax of functions in python:

                   def function_name([arg1,....,arg n]):

                          statement 1

                          ........

                          statement n

                          [return value]

                   variable = function_name([value1,......,value n])

Control Structures

• In general, Control structures decide the flow of the program execution.

• The most commonly used control structures in python are

• Sequential: control flows through all the statements, in the order of how the code is written.

• Selection: Depends on the condition, control flows to the different statements.

• Iteration: Certain blocks of code(statements) will be executed repeatedly.

Basics of Python

• Python was created by Guido van Rossum in 1991 as a general-purpose programming language.

• It is interpreted and interactive language. 

• Python is an open-source language under a general public license (GPL). 

• It supports both object-oriented and structured styles of programming.

Python Operators

• Operators are special symbols that are used to perform operations on the variables and the values.

• Consider an expression 10 + 20 = 30. Here, + is an operator that performs addition. 10 and 20 are called operands and 30 is the output of the operation.

• In general, the operand is a variable or a value that the operator operates on.

• The most commonly used operator groups in python language are listed below

• Arithmetic Operators

• Comparison/Relational Operators

• Logical Operators

• Assignment Operators

• Bitwise Operators

• Identity Operators

• Membership Operators

• Let's have a look at each operator with their syntax.
