Python Program to Find ASCII Value of a Character or Digit Entered by the User

Explanation of ASCII

ASCII (American Standard Code for Information Interchange) is a character encoding system that assigns a unique numeric value to each character, digit, or symbol.

Examples:

• 'A' → 65
• 'a' → 97
• '0' → 48
• '@' → 64

ASCII values are widely used in text processing, sorting, and data transmission.

Python Program

1. User Input (raw_input())

   ch = raw_input("Enter a character:\t")
   

   • raw_input() takes user input as a string (used in Python 2).
   • The user enters a single character or digit.

2. Finding ASCII Value (ord())

   print "The ASCII value of '" + ch + "' is ", ord(ch)
   

   • ord(ch) returns the ASCII value of the entered character.
   • print displays the output.

Key Takeaways

• ASCII assigns numeric codes to characters and digits.
• ord() returns the ASCII value of a character.
• Python 2 uses raw_input(), while Python 3 uses input().

Output

Enter a character:	r
The ASCII value of 'r' is  114
