ord() in Python
FREE
The ord() function in Python is a method that converts a character to its Unicode. The Unicode Standard provides a unique number for every character, no matter what platform, device, application or language.
Syntax of ord() in python
The Syntax of the ord() is as follows:
Parameter Value of ord() in python
The function can only take one parameter,
- character, whose Unicode value is desired.
Return Value of ord() in python
Return Type: int
The function returns an integer value which is equivalent to the Unicode value of the provided character.

What is ord() Function in Python?
The ord() function in Python is utilized to retrieve the Unicode code point of a single character. It accepts a single-character string as input and produces an integer representing the Unicode code point of that character. If the input string's length is not exactly 1, the ord() function raises a TypeError.
So now we are using a standard encoding format but how do we know what character is what? We map every character to some value. Sometimes we require this value and for that, we have to use the ord function in python.
The ord function is short of the ordinal which means a number. The ord function in python accepts a single character as an argument and returns an integer value representing the Unicode equivalent of that character.

Example 2: Python Program to Find the Unicode Value of the Digit
It turns out that the digit 0 does not have the Unicode value of 0, so what is it's and other digit’s Unicode value?

Example 3: What Happens If We Pass More Than One Character in the ord() Function?
The ord function takes only one character as input, Here's what will happen if we pass an input whose size is greater than 1.

Python ord() and chr() Functions
The chr() method returns a string representing a character whose Unicode code point is an integer.
Syntax: chr(num), where num is integer value
Output:
Conclusion
- Unicode is an international standard for character encoding.
- ord() in Python is a built-in function that helps retrieve the Unicode value of a character.
- It takes a character as input.
- It returns an integer value corresponding to the character.
