Take advantage of ValueTuples to return multiple values from a method with better performance than Tuples. Credit: Thinkstock A Tuple is a data structure that comprises an ordered, finite sequence of immutable, heterogeneous elements of fixed sizes. When we say the elements in a Tuple are ...
tuple1, tuple2 = technology([1, 2], ['Python', 25000]) 1. Use the Simplest Python Return Tuple You can use a tuple as the return value from a function in Python by simply enclosing the values you want to return inparentheses– (), separated by commas. Returning a tuple from a fun...
3. What is list() in Python? The list() function is a built-in Python function that converts an iterable (like a string, tuple, or set) into a list. This is particularly useful when you need to manipulate individual elements of an iterable or when you want to convert a string into...
To reverse a tuple in Python: Create a new tuple eg: a = (1, 2, 3). Pass the tuple to the built-in reversed() function. Now, pass the reversed iterator object to tuple() function. Consider, that you have the following tuple: ...

You should use .items() to access key-value pairs when iterating through a Python dictionary. The fastest way to access both keys and values when you iterate over a dictionary in Python is to use .items() with tuple unpacking.To get the most out of this tutorial, you should have a ba...
The all() function takes an iterable (like a tuple) as input and returns True if all elements in the iterable evaluate to True, and False otherwise. To compare two tuples using all(), we can convert the comparison of each element in the tuples to a Boolean value and pass them as ...
