Python String translate()
Python String.translate() method translates the calling string based on the dictionary or mapping table given as argument. The translation is basically replacing specified characters with their respective replacements, and/or deleting specific characters.
In this tutorial, we will learn the syntax and examples for translate() method of String class.
Syntax
The syntax of String translate() method in Python is
str.translate(table)
where
| Parameter | Required/Optional | Description |
|---|---|---|
| table | Required | Dictionary or Mapping table. If a dictionary, then it specifies the replacements. If a mapping table, then it specifies the replacements and/or removals . |
Examples
Translate String using a Dictionary
In the following program, we take a string 'apple' in x, and replace 'p' with 't', and 'e' with 'm' using translate() method.
If we pass a dictionary to translate() method, then the search values and replacements must be provided as ASCII values.
Example.py
x = "apple"
result = x.translate({112: 116, 101: 109}) //{'p':'t', 'e': 'm'}
print("Original String :", x)
print("Translated String :", result) Try Online Output
Original String : apple Translated String : attlm
Replace Characters based on Mapping
In the following program, we take a string 'apple' in x, create a mapping to replace 'p' with 't', 'e' with 'm', and delete the characters 'abc' using maketrans() method, and pass the mapping to translate() method.
Example.py
x = "apple"
mapping = x.maketrans('pe', 'tm', 'abc')
result = x.translate(mapping)
print("Original String :", x)
print("Translated String :", result) Try Online Output
Original String : apple Translated String : ttlm
Conclusion
In this Python Tutorial, we learned how to translate a string, using String method – translate(), with examples.
