Python String translate() Function

The String translate() method is used to replace specific characters in a string with other characters or remove them altogether. It requires a translation table that maps the characters to be replaced to their replacements.

note

The translation table can be generated using the maketrans() static method.


## Syntax

```python
my_string.translate(table)

translate() Parameters​

Python String translate() function parameters:

ParameterConditionDescription
tableRequiredA translation table that maps the characters to be replaced to their replacements.

translate() Return Value​

Python String translate() function returns a string where each character is mapped to its corresponding character as per the translation table.

Examples​

Example 1: Replacing Characters with maketrans() and translate()​

This example demonstrates how to use translate() with a translation table generated by maketrans(). It replaces vowels with digits in the string "tutorialreference".

text = 'tutorialreference'
table = str.maketrans('aeio', '4310')
translated_text = text.translate(table)
print(translated_text) # Output: tut0r14lr3f3r3nc3

output

tut0r14lr3f3r3nc3

Example 2: Removing Characters with maketrans() and translate()​

This example shows how to use translate() to remove characters from a string. It removes all vowels from "tutorialreference".

text = "tutorialreference"
vowels = "aeiouAEIOU"
table = str.maketrans("", "", vowels)
translated_text = text.translate(table)
print(translated_text) # Output: "ttrlrfrnc"

output

ttrlrfrnc

Example 3: Replacing Characters with ASCII Mapping with translate()​

This example demonstrates replacing characters using an ASCII mapping table directly with translate() method.

This replaces the t, u, r characters with the corresponding uppercase letter.

text = "tutorialreference"
table = {116: 84, 117: 85, 114: 82}
print("The string before translating is: ", text)
print("The string after translating is: ", text.translate(table))

output

The string before translating is:  tutorialreference
The string after translating is:  TUToRialRefeRence

Example 4: Removing Punctuation with maketrans() and translate()​

This example removes all punctuation from a string using translate() and a translation table generated by maketrans().

import string

text = "https://tutorialreference.com"
table = str.maketrans("", "", string.punctuation)
translated_text = text.translate(table)
print(translated_text) # Output: httpstutorialreferencecom

output

httpstutorialreferencecom
note

string package offers has a predefined string containing all punctuation symbols. You just need to import string package to use it.

import string
print(string.punctuation)

output

!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
