2. Sort the List of Tuples in Python You can sort a list of tuples in Python by using thesort() method, to specify the criteria for sorting, you can use thekeyparameter with value aslambdafunction that calculates the value used for sorting. Note that this method updates the original li...
In Python, lists and tuples are collection objects that can contain multiple values. Sometimes, you need to get the number of elements contained in these objects. When using the NumPy library, you can find the shape of an array using the.shapeproperty: ...

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...
5. What is the difference between split() and list() in Python? split() divides a string by a delimiter, while list() converts each string character into a separate list element. For example: # Using split() string = "apple,banana,cherry" list_of_fruits = string.split(",") print(...
