Overview
You can return a range of characters by using the slice syntax.
A range of characters can be returned from a string by using the slice syntax.
Note
Arrays count starting from zero NOT one. So item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on.
Slicing with a Start and End Point
Specify the start index and the end index, separated by a colon, to return a part of the string.
The following gets the characters from position 2 to position 5 (not inclusive).
x = "Hello World"
print(x[1:5])Output:
elloSlicing From the Start
By leaving out the start index, the range will start at the first character.
x = "Hello World"
print(x[:5])Output:
elloSlicing to the End
By leaving out the end index, the range will go to the end.
x = "Hello World"
print(x[1:])Output:
ello WorldNegative Indexing
Use negative indexes to start the slice from the end of the string.
x = "Hello World"
print(x[-5:-2])Output:
WorPython 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.
