Practical 7: Program to demonstrate the usage of ord() and chr() functions.
Problem Statement
Write a Python program to demonstrate the usage of ord() and chr() functions.
The program should:
- Accept a character from the user and display its ASCII value using ord().
- Accept an ASCII value from the user and display its corresponding character using chr().
Solution Code
# Program to understand ord() and chr() functions
# Taking a character input from the user
char = input("Enter a character: ")
# Getting the ASCII value of the character
ascii_value = ord(char)
# Taking an ASCII value as input
ascii_num = int(input("Enter an ASCII value (between 0 to 127): "))
# Getting the corresponding character
character = chr(ascii_num)
# Displaying the results
print(f"ASCII value of '{char}' is: {ascii_value}")
print(f"Character corresponding to ASCII value {ascii_num} is: {character}")
Output:
- The program takes a character input from the user and returns its ASCII value.
- It then takes an ASCII value as input and returns the corresponding character.
Example output:
Enter a character: A
Enter an ASCII value (between 0 to 127): 97
ASCII value of 'A' is: 65
Character corresponding to ASCII value 97 is: a
Process finished with exit code 0
Explanation
Below is the explanation of F.E. PPS Unit 3 Practical 7 solution where we have written Python program to demonstrate the usage of ord() and chr() functions.
- Taking a Character Input:
- The input() function is used to accept a single character from the user.
- Using ord() Function:
- ord(char) → Converts a character to its ASCII value.
- Example: ord(‘A’) returns 65.
- Taking an ASCII Value as Input:
- The user enters a numeric value representing an ASCII code.
- Using chr() Function:
- chr(ascii_num) → Converts an ASCII value to its corresponding character.
- Example: chr(97) returns ‘a’.
- Displaying the Results:
- The program prints both conversions using formatted strings.
Key Concepts Learned
- ord() Function
- Converts a character to its ASCII value.
- Example: ord(‘B’) → 66.
- chr() Function
- Converts an ASCII value back to its corresponding character.
- Example: chr(100) → ‘d’.
- ASCII Values
- The standard ASCII table assigns numbers (0-127) to characters.
- Uppercase letters: A-Z (65-90), Lowercase letters: a-z (97-122).
