You can access tuple items by referring to the index number, inside square brackets:ExampleGet your own Python Server Print the second item in the tuple: thistuple = ("apple", "banana", "cherry") print(thistuple
APython tupleis an immutable sequence of values, typically used to group related data together. To access the elements of a tuple, you can use indexing or slicing andforloop. In this article, I will explain how to access tuple elements using all these methods with examples. Advertisements 1....
The first element represents the coordinate x, and the second represents the y-coordinate. When a function returns numerous values, tuples are also helpful. You can group all the values in a tuple and return the tuple as one object as opposed to returning every value individually. Overall, t...

Python sequence types behave like MATLAB® cell arrays. Get a subsequence using smooth-parenthesis () indexing. li = py.list({1,2,3,4}); res = li(2:3) res = Python list with values: [2.0, 3.0] Use string, double or cell function to convert to a MATLAB array. Use curly brace...
