Factorial of a Number by a User-Defined Function (PCTS)

Factorial of a Number

There are a number of ways to find the factorial of a number (obviously, it going to a whole number 😆). Out of all of them today, I'm going to show you the user-defined code I created to find the factorial of any whole number. Trust me, it's cool 😎 just give it a try...

Copy the following code:


#Factorial Calculator
def fact(x):
    p = 1
    while x>0:
        p = p*x
        x = x-1
    print(p)
    print("Thank you for using factorial calculator ;)")

while True:
    n = input("Enter a number:")
    if n.isdigit()and int(n)>=0:
        n = int(n)
        fact(n)
        break

Our view towards Python (as a programming language)

Python - The language of the future Introduction When we hear the term programming language, we usually talk about high-level programming language which are those programming language having a lucid (or easy-to-read) syntax and are later converted to low-level language (binary) , which is understandable by the computer. Programming language has always been an area of interest over the passing years since the very early days of ' Fortran ' (created by John Backus at IBM ). To this day, dozens of programming language has been created by different 'Computer Scientists' around the world. What is Python? What is Python? Many of you will describe a large scary snake 🐍, which isn't actually wrong 😅. But here we are talking about a programming language. Similarly, Python is also a high-level and interepreted programming language created by Guido van Rossum in the late 1980s . It was first released in 1991 as a successor to ABC Programming language . It known fo...

For Loops

The for loop By polygraphus on shutterstock Def: The for loop is also known as the counting loop and is designed to process the items of any sequence, such as a list or a string, one by one. General form of for loop: The general form of the for loop is given below: for <variable> in <sequence>: statements to repeat

Character Case Swapping (PCTS)

Python Codes The Series -1 ©Photo by wiki commons Not only in Python but also in the day-to-day life, the letters in English alphabets are characterized into two cases viz. upper case and lower case. Our first program will be a general fun program for the beginners. In this program, we will learn to swap the cases of the letters of English alphabets being entered by the user with the help of a few lines of Python code. For example: If the user enters: " hoLa AmIGo" , the python program would convert this string into " HOlA aMigO" . The Program is noted below: string=input("Enter a string :") length=len(string) s='' for i in range(length): if string[i].islower(): s=s+string[i].upper() elif string[i].isupper(): s=s+string[i].lower() else: s=s+string[i] print(s) FOR QUICK REFERENCE: The len() function gives the length of the string and the the input() function takes input from the user. Hope you like i...
