How to Find ASCII Value in Python? ASCII Value of Character

In programming and character encoding, ASCII (American Standard Code for Information Interchange) plays a fundamental role. ASCII is a widely used character encoding scheme that assigns unique numerical values to represent characters. Each character is assigned a specific ASCII value, which allows computers to store, process, and transmit textual data.

In this tutorial, we will learn how to convert ASCII value to character in Python. We will provide a step-by-step guide, complete with examples and code explanations, to help you understand the concept and implement it in your Python programs effectively.

Finding ASCII values in Python is an important task in various programming scenarios, such as character manipulation, text encoding conversions, and data analysis. ASCII values allow us to represent characters numerically, enabling computers to work with textual data in a standardized way.

The importance of understanding ASCII values extends beyond basic character encoding. It finds applications in tasks such as password validation, string comparisons, cryptographic algorithms, and network protocols. 

By learning how to get ASCII value of char in Python, you will acquire a valuable skill in character manipulation and text processing.

It is worth noting that the ASCII value represents the numerical value assigned to a character in the ASCII scheme. This numerical value is different from the character itself. 

For example, the ASCII value of the letter 'A' is 65, while the ASCII value of the letter 'B' is 66. 

ASCII values allow us to perform operations and transformations on characters based on their numerical representations. The programs for ASCII value in Python given below can be practised with the online Python compiler. To learn the basics of this programming language, you can go through our detailed Python Tutorial. 

Program to Find ASCII Value of Character in Python

To find the ASCII value of a char in Python, you can use the built-in ord() function. The ord() function takes a character as input and returns its corresponding ASCII value. Here's an example program:

Code

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

# Get the ASCII value using the ord() function
ascii_value = ord(character)

# Print the ASCII value
print("The ASCII value of", character, "is", ascii_value)

Output

Enter a character: A
The ASCII value of A is 65

Explanation

In this program, the user is prompted to enter a character. The ord() function is then used to get the ASCII value of the character, which is stored in the variable ascii_value. 

Finally, the program prints the ASCII value to the console.

Note that the ord() function only accepts a single character as input. If you enter a string with multiple characters, it will only consider the first character and ignore the rest.

ASCII Value of A to Z in Python

To find the ASCII values of all uppercase letters from A to Z in Python, you can use a loop to iterate over the range of ASCII values corresponding to these characters. Here's an example program:

Code

# ASCII values of A to Z
for char in range(ord('A'), ord('Z') + 1):
    print(f"The ASCII value of {chr(char)} is {char}")

Output

The ASCII value of A is 65
The ASCII value of B is 66
The ASCII value of C is 67
The ASCII value of D is 68
The ASCII value of E is 69
The ASCII value of F is 70
The ASCII value of G is 71
The ASCII value of H is 72
The ASCII value of I is 73
The ASCII value of J is 74
The ASCII value of K is 75
The ASCII value of L is 76
The ASCII value of M is 77
The ASCII value of N is 78
The ASCII value of O is 79
The ASCII value of P is 80
The ASCII value of Q is 81
The ASCII value of R is 82
The ASCII value of S is 83
The ASCII value of T is 84
The ASCII value of U is 85
The ASCII value of V is 86
The ASCII value of W is 87
The ASCII value of X is 88
The ASCII value of Y is 89
The ASCII value of Z is 90

Explanation

In this program, we use a for loop to iterate over the range of ASCII values from the ord('A') (which is the ASCII value of 'A') to ord('Z') + 1 (which is the ASCII value of 'Z' plus one to include 'Z' in the loop). 

Inside the loop, we use the chr() function to convert each ASCII value back to its corresponding character and print the result.
