Welcome to our tutorial on how to find the ASCII value of a character in Python! In this tutorial, we will be discussing how to use the built-in function “ord()” to find the ASCII value of a given character.
Python Program to Find ASCII Value of Character
# Find ASCII Value of Character in python # entered value will be converted string char=str(input("Enter the character: ")) # ord() function to convert a character to an integer ASCII value print("The ASCII value of '" + char + "' is", ord(char))
Step 1: The first step in finding the ASCII value of a character is to take a character as input from the user. In this example, we are using the “input()” function to take input from the user and store it in the variable “char”.
Step 2: The input value is then converted to a string using the str() function, to ensure that we’re working with a string type.
Step 3: The ord() function is used to convert the character entered by the user to its corresponding integer ASCII value. The ord() function takes a single character as input and returns an integer value representing its ASCII value.
print(“The ASCII value of ‘” + char + “‘ is”, ord(char))
Step 4: The result of the ord() function is printed to the console using the print() function. The output message includes the original character entered by the user as well as its corresponding ASCII value.
Once we have the character, we can use the built-in function “ord()” to find the ASCII value of the character. The ord() function takes a character as an argument and returns the corresponding integer ASCII value of that character.
The output of the program will look something like this:
Enter the character: N The ASCII value of 'N' is 78
In this example, the user enters the character “A”, which has an ASCII value of 65. The program then prints out the message “The ASCII value of ‘A’ is 65” to the console.
The input is being taken from the user and stored in the variable “char”. The input function returns the input as a string, so it is important to convert the value to string before using it in further calculations. Finally, we can use the “print()” function to display the result of the calculation. In this line, we are using the concatenation operator(+) to print the result in the desired format.
Usage of ASCII Value of Character:
The use of this code snippet is to find the ASCII value of a character entered by the user in Python.
Here are a few scenarios where you might want to use this code:
- Input validation: If you’re building a program that expects input from users, you might want to validate the input to ensure that it only contains characters that are valid according to the ASCII system. By using this code, you can check if the user has entered a valid ASCII character and get its corresponding ASCII value.
- Character manipulation: If you need to perform operations on individual characters in a string, such as converting them to uppercase or lowercase, or shifting their position in the string, it can be helpful to know the ASCII value of each character. This code can be used to get the ASCII value of a character that needs to be manipulated.
- Cryptography: In cryptography, ASCII values can be used as part of encryption or decryption algorithms to transform plaintext into ciphertext and back again. This code can be used to get the ASCII value of a character that needs to be encrypted or decrypted.
In conclusion, finding the ASCII value of a character in Python is a simple task that can be achieved using the built-in function “ord()”. By understanding how to use this function, you’ll be able to find the ASCII value of a given character in a more precise way.
Additionally, this example illustrates the use of ord function, input function, and string concatenation in Python. With this tutorial, you now have a solid understanding of how to find the ASCII value of a character in Python.
