Python - Convert String to unicode characters
In this tutorial, we'll learn how to convert a string into its corresponding Unicode (code point) representation in Python.
Objective:
Convert each character in a string to its Unicode code point.
For Example: Given the string:
string = "hello"
The conversion should produce:
[104, 101, 108, 108, 111]
Step-by-step Solution:
1. Use the ord() Function:
The built-in Python function ord() returns an integer representing the Unicode character.
unicode_val = ord('h') # This will return 104 2. Convert the Entire String:
Using a list comprehension, iterate over the string and convert each character to its Unicode value.
unicode_list = [ord(char) for char in string]
Complete Code:
Here's the complete code to convert a string into its Unicode representation:
# Sample string string = "hello" # Convert string to list of Unicode values unicode_list = [ord(char) for char in string] print(unicode_list)
When executed, the code will produce:
[104, 101, 108, 108, 111]
Additional Notes:
Unicode provides a unique number for every character, no matter the platform, device, application, or language.
The
ord()function works for a single character string. It returns the Unicode code point for that character.If you want to convert Unicode values back to their character representations, you can use the
chr()function:char_representation = chr(104) # This will return 'h'
Through this tutorial, you've learned how to convert each character in a string into its corresponding Unicode representation in Python. This knowledge is particularly useful when dealing with internationalized applications or performing certain types of text processing or encryption.
