Python Right String Part

Get the right part of strings by using a negative starting slice index. The syntax is shown.
String right. A string contains many characters. Often we want just the last several characters—the ending, rightmost part of the string.Strings
With a special method, we can get just the right part. But often using slice syntax directly is a better choice as it involves less code.
An example. Here we introduce a "right" method. Pay close attention to the return value of right(). It uses slice syntax with a negative start, and no end.

Tip: We do not specify an end—this means the slice continues to the end of the string.

And: We use a negative start—this means we start from that many characters from the end of the string.

Python program that gets right part of strings def right(value, count): # To get right part of string, use negative first index in slice. return value[-count:] # Test the method. source = "soft orange cat" print(right(source, 3)) print(right(source, 1)) # We can avoid the "right" method entirely. # ... We can also use len in the expression. print(source[-2:]) print(source[len(source) - 2:]) Output cat t at at
Some notes. If you are using strings in Python, learning the slice syntax is essential. We get "right" and "left" parts as slices.Substring
No substring method. There is no substring() or right() method in Python. With slice indexes (some of which can be omitted) we get string parts.
