Quick Reference
The Python string maketrans() method returns a mapping table that can be used with the translate() method to replace specified characters.
txt = "Hello Jon!"
mytable = str.maketrans("J", "D")
print(txt.translate(mytable))Note
Python string methods return new values, and DO NOT change the original string.
Output
Hello Don!Syntax
str.maketrans(x, y, z)Parameters
| Parameter | Description |
|---|---|
| x | If only one parameter is specified, this has to be a dictionary describing how to perform the replace; if two or more parameters are specified, this parameter has to be a string specifying the characters you want to replace (required) |
| y | A string with the same length as parameter x; each character in the first parameter will be replaced with the corresponding character in this string |
| z | A string describing which characters to remove from the original string |
Python Notes:
- The most recent major version of Python is Python 3; however, Python 2 is still in use and quite popular, although not being updated with anything other than security updates
- Python uses new lines to complete a command, as opposed to other programming languages which often use semicolons or parentheses
- Python relies on indentation, using whitespace to define scope, such as the scope of loops, functions, and classes; other programming languages often use curly-brackets for this purpose
- Python string methods return new values, and DO NOT change the original string
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
