ASCII stands for American Standard Code for Information Interchange. It is a numeric value given to different characters and symbols, for computers to store and manipulate. For example: ASCII value of the letter 'A' is 65. Check out the complete list of ASCII values.
# Program to find the ASCII value of the given character
# Take character from user
c = input("Enter a character: ")
print("The ASCII value of '" + c + "' is",ord(c))
Enter a character: p
The ASCII value of 'p' is 112
Here we have used
ord() function to convert a character to an integer (ASCII value). This function actually returns the Unicode code point of that character. Unicode is also an encoding technique that provides a unique number to a character. While ASCII only encodes 128 characters, current Unicode has more than 100,000 characters from hundreds of scripts.
We can use
chr() function to inverse this process, meaning, return a character for the input integer.
>>> chr(ord('S') + 1)
chr() are built-in functions.
