  Today, I started Nested Loop. It is a for or while loop running inside another loop. It is mainly used for executing repetitive tasks, while another macro task is simultaneously being executed.   ```python # Write a program that inputs the number of rows and columns, then prints an alternating matrix of 1s and 0s where the element is 1 if the sum of its row and column indices is even, and 0 otherwise r = int(input("Enter number of rows ")) c = int(input("Enter number of columns ")) for i in range(0,r):         for j in range(0,c):             s = i + j             if s%2==0:                 print(1, end=" ")             else:                 print(0, end=" ")  ...

  Today is June 22nd, the third day of the 100 Days of Python Coding challenge. I am doing some Number Manipulation questions in Python that use a while loop and digit extraction.The first program checks for an Armstrong Number. To solve it, I use a while loop and a counter variable to get the number of digits in the input number. Then, with another loop, I use the while loop again, but this time extract a digit, raise it to the power of its number of digits and then add their sum in a separate variable 's'.```python # Armstrong Number. An Armstrong number (like 153 or 371) is a number equal to the sum of its own digits raised to the power of the number of digits n = int(input("Enter a number to check for Armstrong Number")) p = n s=0 c = 0 while n>0:     c=c+1     n = n//10 n = p while n>0:     d = n%10     print(f"Current dig...

Today is Day 2 of my 100 Days of Python Challenge. Yesterday, I learned about the Conditional Statements like if, else and elif, which are used to execute a block of code if the required conditions are met. Using these, I solved two incredibly common coding questions that are asked in the exams.Today's goal is to solve some number manipulation questions in Python to brush up on my coding knowledge. The first program is very simple. It basically inputs (asks for a 3-digit number) a three-digit number. Then, using division and modulo operations to extract the digit into 3 different variables, without using loops. And finally, adds the digits, stores and prints the summation of its digits. While writing this program, I learned that using // means that only the integer division takes place (ex. 5//2 = 2 and 5/2 = 2.5). ```python # number manipulation in python # Digit Extraction and sum of digit of a 3-digit number n = int(input("Enter a number of 3 digit")) d1 = n //100 #  ...

Today is the first day of the coding challenge I took (although by the time I finish writing this post, it will be past 12 in the morning). Yesterday, I played around with basic Python syntax, such as print, which lets us display text in the console. Today, my goal is to learn more about basic Python syntax and work through a few practice questions. This was one problem that I solved yesterday. These kinds of questions are asked repeatedly in board exams, and I am very familiar with them. I will do more of these kinds of questions tomorrow. #Electricity Bill question in Python # An electricity board charges for electricity delivered to domestic consumers based on the number of units consumed. # For the first 100 units: ₹4.00 per unit # For the next 200 units: ₹6.00 per unit # Beyond 300 units: ₹8.00 per unit # A fixed meter charge of ₹200 is added to every bill. # Given the units consumed, calculate the total bill. units = int(input("Enter units consumed")) fixc = 200 amt = 0...

Python is one of the most popular programming languages. It is simple to understand and easy to learn for beginners. Although I am not exactly a beginner. I did spend 4 years in school (from grade 9 to 12) in school learning Java and practising problems like String Manipulation, Array Operations and recently Stacks and Queues. I am starting college this year, and the syllabus includes Python. So, to get used to a completely new programming language and to brush up on my existing programming skills, I have decided to challenge myself with the 100 Days of Python Challenge. As the name suggests, I will practise Python for the next 100 days and give my all to at least get to the intermediate level. I will also try some interesting Python projects to showcase on my GitHub profile. I was supposed to post this, actually, yesterday, on 19th June, which I decided to call Day 0 (for getting to know basic Python commands like 'print' statements and variables). But, I started late at night...
