Python, a dynamic and versatile programming language, is packed with a multitude of built-in functions, each designed to perform a specific task. Among these numerous functions, the ord() function stands out due to its unique functionality and use in handling Unicode characters.
The ord() function in Python is a built-in function that takes a single character string as an input and returns the Unicode code point of that character. This Unicode code point is an integer representation of the character. For instance, the ord() function would return 97 for the character ‘a’ because that’s the Unicode code point for ‘a’ in the Unicode standard. So, let’s dive into the topic and get if anything comes up, you will be able to get the necessary help with Python homework.
What Does the ord() Function Do?
Working with Unicode characters is common in Python programming, especially when dealing with texts from various languages. Unicode is a universal encoding standard that allows representation of characters from virtually all written languages. This is where the ord() function in Python comes into play. It helps programmers manipulate and work with these Unicode characters effectively by converting them into their integer code points.
The ord() function works in tandem with the chr() function. While the ord() function transforms a character into its corresponding Unicode code point, the chr() function does the reverse. Given an integer value, the chr() function returns the corresponding Unicode character. For instance, chr(97) would return the string ‘a’. These two functions, ord() and chr(), often go hand in hand when handling Unicode strings in Python.
Practical Use of the ord() Function
Here’s how you can use the ord() function in Python:
# Using Python's ord() function print(ord('a')) # Outputs: 97
You can also use Python’s ord() function to convert special Unicode characters to their code points. Here’s an example:
# Special Unicode character print(ord('€')) # Outputs: 8364
Similarly, Python’s chr() function can be used to convert this Unicode code point back into the character.
# Using Python's chr() function print(chr(8364)) # Outputs: €
In conclusion, Python’s ord() function is a powerful tool for handling Unicode characters in a string. It allows programmers to convert characters into their corresponding Unicode code points, which can be useful in a variety of programming tasks, such as comparing characters, sorting strings, and more. The ability to work with Unicode characters expands the versatility of Python, making it an ideal language for global software development that involves multiple languages and character sets.

What does the Python ord() function do?
The Python ord() function is a built-in function that returns the Unicode code point of a given character. This is an integer representation of the character in the Unicode standard.
How can you use the Python ord() function?
You can use the Python ord() function by providing a single character as an argument. For example, ord(‘a’) will return 97, which is the Unicode code point for the character ‘a’.
What is the significance of Unicode in Python?
Unicode is an encoding standard that represents characters from virtually all written languages. Its significance in Python lies in enabling the consistent handling of text data from multiple languages. Python’s ord() and chr() functions are built to work seamlessly with Unicode characters.
What does the Python chr() function do?
The Python chr() function does the reverse of the ord() function. It converts a Unicode code point, given as an integer, back into its corresponding character. For instance, chr(97) will return the string ‘a’.
Can the Python ord() function convert a Unicode character to an integer?
Yes, the Python ord() function can convert any Unicode character to its corresponding integer code point.
What happens if you pass a string with more than one character to the Python ord() function?
If you pass a string with more than one character to the ord() function, Python will raise a TypeError. The ord() function is designed to take a single character as input.
How can you convert a list of integers to a string using Python’s chr() function?
To convert a list of integers to a string using Python’s chr() function, you can iterate over the list and apply the chr() function to each integer. The resulting characters can then be joined together into a string. For example:
integer_list = [104, 101, 108, 108, 111] string = ''.join(chr(i) for i in integer_list) print(string) # Outputs: 'hello'
