Python String translate() method Tutorial
Hello in this tutorial, we will understand how to use the String translate method in python programming.
1. Introduction
The translate()
method in python programming is used to return a string in which all characters are translated using the translation table. The method is represented by the following syntax:
string.translate(translation_table) where, translation_table contains the mapping between two characters and is created by maketrans()
The method returns a string where each character is mapped to its corresponding character as per the given translation table.
- If the character is not specified in the translation table then it will not be replaced
- If you use a dictionary object then you must use ASCII codes instead of the characters
1.1 Setting up Python

I am using JetBrains PyCharm as my preferred IDE. You are free to choose the IDE of your choice. Let us dive in with the programming stuff now.
2.1 Python String translate() method Tutorial
Let us understand the different use cases of the translate()
method in python programming.
translate() method
# python translate() tutorial # Returns a string where each character is mapped to its corresponding character # in the translation table # Syntax - string.translate(translation_table) # where, # translation_table contains the mapping between two characters and is created by maketrans() # translation using maketrans() method def translation(orig_string): print('Original string = {}'.format(orig_string)) string1 = 'wxyz' string2 = 'efgh' translation_table = orig_string.maketrans(string1, string2) # translated string translated_string = orig_string.translate(translation_table) print('Translated string = {}'.format(translated_string)) # translation using manual translation def manual_translation(orig_string): print('Original string = {}'.format(orig_string)) # dictionary # http://sticksandstones.kstrom.com/appen.html translation_table = {117: None, 118: None, 119: None, 120: None, 121: 105} # translated string translated_string = orig_string.translate(translation_table) print('Translated string = {}'.format(translated_string)) # driver code if __name__ == '__main__': random_string = 'uvwxyz' translation(random_string) print('\n') manual_translation(random_string)
If everything goes well the following output will be shown in the IDE console.
Console Output
Original string = uvwxyz Translated string = uvefgh Original string = uvwxyz Translated string = iz
