### Strings in Python

What is String in python?
• In Python, String is a sequence of characters enclosed by either single quotes or double-quotes.
• Example: 'Python', "Geek4Tutorial"
• Strings are immutable.
• Each value in a string is called character.
Creating a String:
• Strings can be created by enclosing the sequence of characters inside a single quote or double quote and assigning it to a variable.
• Sometimes triple quotes can also be used to create a string, even though triple quotes are used to represent Multiline strings and Docstrings.
• We can access the characters(element) in the string just like the index using index position.

### Example python programs: Functions basics

Simple python programs to practice:

1) Write a Python function Factorial(n) which returns the factorial of the given number(n).

2) Write a Python function, Square(num) which returns the square of the given number(num).

3) Write a Python function, Sum(n) which returns the sum of first n numbers.

4) Write a Python function, Palindrome(num) that accepts an integer num as input and returns true/false based on condition.

Ex: num = 12321 ---> output = 12321 ----> then given number is palindrome.

5) Write a Python function, check_strong_number(num) that accepts a positive as input, and returns true/false based on condition.
• A number is said to be a Strong number if the sum of the factorial of each digit is equal to the given number.
Ex: 145 is strong number as (1! =1) + (4! = 24) + (5! = 120) = 145.

### 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.

### About: Introduction to Python Course

Introduction to Python:

This course is to introduce the basics of the Python programming language.

• 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.
