Python Introduction

Python Introduction:-

What is Python?

Python is a popular programming language. It was created by Guido van Rossum, and released in 1991. Python programmers are often called Pythonists or Pythonistas.

It is used for:

web development (server-side),
software development,
mathematics,
system scripting.

What can Python do?

Python can be used on a server to create web applications.
Python can be used alongside software to create workflows.
Python can connect to database systems. It can also read and modify files.
Python can be used to handle big data and perform complex mathematics.
Python can be used for rapid prototyping, or for production-ready software development.

Why Python?

Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc).
Python has a simple syntax similar to the English language.
Python has a syntax that allows developers to write programs with fewer lines than some other programming languages.
Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick.
Python can be treated in a procedural way, an object-oriented way, or a functional way.

Python Syntax compared to other programming languages:-

Python was designed for readability and has some similarities to the English language with influence from mathematics.
Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses.
Python relies on indentation, using whitespace, to define scope; such as the scope of loops, functions, and classes. Other programming languages often use curly brackets for this purpose.

EXAMPLES:-

print("Hello, World!")

HackerRank Tuples Solution in Python

HackerRank Tuples Solution in Python Task Given an integer,n, and n space-separated integers as input, create a tuple, t, of those n integers. Then compute and print the result of hash(t). Note: hash() is one of the functions in the __builtins__ module, so it need not be imported. Input Format The first line contains an integer,n, denoting the number of elements in the tuple. The second line contains n space-separated integers describing the elements in tuple t . Output Format Print the result of hash(t) . Sample Input 0 2 1 2 Sample OUTPUT- 3713081631934410656 n = int(input()) int_list = [int(i) for i in input().split()] int_tuple = tuple(int_list) print(hash(int_tuple))

How to check if the given number is Even or odd-

1. How to check if the given number is Even or odd- We can determine whether a number is even or odd. This can be tested using different methods. The test can be done using simple methods such as testing the number’s divisibility by 2. If the remainder is zero, the number is even. If the remainder is not zero, then the number is odd. The following algorithm describes how a C program can test if a number is even or odd. CODE:- #include <stdio.h> int main () { int num;//variable declaration printf("Enter any num: ");// take input from user scanf("%d",&num);// declare input if(num%2==0) { printf("The num %d is even",num); } else { printf("The num %d is odd",num); } return 0; } ALGORITHM:- Step 1. Start Step 2 . Enter a number. Step 3. If...

Binary to Decimal conversion program

3. Binary to Decimal conversion program using C language:- The C program converts binary number to decimal number that is equivalent. A decimal number can be attained by multiplying every digit of binary digit with a power of 2 and totaling each multiplication outcome. The power of the integer starts from 0 and counts to n-1 where n is assumed as the overall number of integers in a binary number. Ex:- ( 101100001 ) 2 =( 353 )10 ALGORITHMS:- Step 1: Start Step 3: The user is asked to enter a binary number as an input Step 4: Store the quotient and remainder of the binary number in the variable rem Step 5: Multiply every digit of the entered binary number beginning from the last with the powers of 2 correspondingly Step 6: Repeat the above step...
