How do I find the ASCII value of a character in Python?

Finding the ASCII Value of a Character in Python

Retrieving the numerical representation of a character as its ASCII value is a fundamental task in Python programming. Here's how you can accomplish this:

Getting the ASCII Value

Python provides the ord() function, which returns the integer value corresponding to the given character. For instance:

>>> ord('a')
97

This returns the ASCII value of the lowercase letter 'a', which is 97.

Converting Back to a Character

To convert the ASCII value back to its character representation, you can use the chr() function. For example:

>>> chr(97)
'a'

Incrementing and Decrementing ASCII Values

Using ord() and chr(), you can perform operations to increment or decrement the ASCII value of a character. For instance:

>>> chr(ord('a') + 3)
'd'

This shifts the character 'a' three positions to the right in the ASCII table, resulting in the letter 'd'.

Unicode Support

Python 2 supported the unichr() function to work with Unicode characters, but in Python 3, chr() can handle Unicode as well.

>>> chr(1234)
'\u04d2'

This returns the Unicode character corresponding to the code point 1234.
