Python Program to find ASCII Code of a Character

April 12, 2023 by Manoj Gautam

In this Python example, you will learn how to Convert Characters to ASCII Code in Python

The abbreviation ASCII stands for American Standard Code for Information Interchange. It is a numerical value assigned to various symbols and characters, which allows computers to store and manipulate them. For instance, the ASCII value of the uppercase letter ‘A’ is 65.

# Prompt the user to enter a character
char = input("Enter a character: ")

# Find the ASCII value of the character using the ord() function
ascii_value = ord(char)

# Print the result
print(f"The ASCII value of '{char}' is {ascii_value}.")

Output

Enter a character: Z
The ASCII value of 'Z' is 90.

Real-world usages of character to ASCII conversion

Program to generate a character frequency histogram

# Python program to find ASCII value of character
 in a given string

# Define a string
text = "The quick brown fox jumps over the lazy dog"

# Define a dictionary to store character frequencies
freqs = {}

# Iterate over each character in the string
for char in text:
    # Check if the character is already in the dictionary
    if char in freqs:
        # If so, increment the frequency
        freqs[char] += 1
    else:
        # If not, add it to the dictionary with a frequency of 1
        freqs[char] = 1

# Print the ASCII values of each character and its frequency
for char, freq in freqs.items():
    ascii_value = ord(char)
    print(f"Character '{char}' (ASCII value: {ascii_value}) appears {freq} times.")

Output

Character 'T' (ASCII value: 84) appears 1 times.
Character 'h' (ASCII value: 104) appears 2 times.
Character 'e' (ASCII value: 101) appears 3 times.
Character ' ' (ASCII value: 32) appears 8 times.
Character 'q' (ASCII value: 113) appears 1 times.
Character 'u' (ASCII value: 117) appears 2 times.
Character 'i' (ASCII value: 105) appears 1 times.
Character 'c' (ASCII value: 99) appears 1 times.
Character 'k' (ASCII value: 107) appears 1 times.
Character 'b' (ASCII value: 98) appears 1 times.
Character 'r' (ASCII value: 114) appears 2 times.
Character 'o' (ASCII value: 111) appears 4 times.
Character 'w' (ASCII value: 119) appears 1 times.
Character 'n' (ASCII value: 110) appears 1 times.
Character 'f' (ASCII value: 102) appears 1 times.
Character 'x' (ASCII value: 120) appears 1 times.
Character 'j' (ASCII value: 106) appears 1 times.
Character 'm' (ASCII value: 109) appears 1 times.
Character 'p' (ASCII value: 112) appears 1 times.
Character 's' (ASCII value: 115) appears 1 times.
Character 'v' (ASCII value: 118) appears 1 times.
Character 't' (ASCII value: 116) appears 1 times.
Character 'l' (ASCII value: 108) appears 1 times.
Character 'a' (ASCII value: 97) appears 1 times.
Character 'z' (ASCII value: 122) appears 1 times.
Character 'y' (ASCII value: 121) appears 1 times.
Character 'd' (ASCII value: 100) appears 1 times.
Character 'g' (ASCII value: 103) appears 1 times.

Program to validate user input


# Prompt the user to enter a character
char = input("Enter a character: ")

# Validate user input
if len(char) != 1:
    print("Please enter a single character.")
else:
    # Get the ASCII value of the character
    ascii_value = ord(char)

    # Print the result
    print(f"The ASCII value of '{char}' is {ascii_value}.")

Output

Enter a character: 1
The ASCII value of '1' is 49.

Program to encode a string as a series of ASCII values


# Define a string
text = "Hello, world!"

# Encode the string as a series of ASCII values
ascii_values = [ord(char) for char in text]

# Print the encoded values
print("Encoded string:", ascii_values)

Output

Encoded string: [72, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100, 33]
