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: a = (1, 2, 3) Here is an example, of how to...
Now what if we desired a function that computed both squares and cubes and returned them both? How can we do that? A Python function can only return one object, not two. The solution is to package the square and cube into a single tuple and return the tuple. ...
res = arr2[tuple(arr1.astype(int))] Let us understand with the help of an example,Python code to index a NumPy array with another NumPy array# Import numpy import numpy as np # Creating some numpy array arr1 = np.array([1, 0]) arr2 = np.array([[1, 2],[3, 4]]) # ...
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...
This way, you’ll get a tuple containing two values, just like theshapeproperty in a NumPy array. Conclusion The Python list and tuple objects are different from the NumPy array object. When you need to get the shape of a list or a tuple, you need to use thelen()function to get the...

Use the Length Command to Find the Length of the List and Print it Indexing in Python Lists In a Python list, each item can be accessed by its index number. Python, like other modern-day languages, is azero-indexed languagei.e., it will start its count from zero (not 1). So, a ...
insert(i, x) Inserts an element before the given index of the array. The following example demonstrates how to create a new array object by joining two arrays: import array # create array objects, of type integer arr1 = array.array('i', [1, 2, 3]) arr2 = array.array('i', [4...
1.2. Nested Tuple A tuple which contains another tuple as its element, it is called nested tuple. nestedTuple = ("hello", ("python", "world")) 2. Accessing Tuple Items We can access tuple items using indices inside square brackets. Positive index begins counting from start of tuple. Nega...
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...
