To access a nested dictionary in Python, apply the access operator twice (or more). For example, let’s access the name of a student data dictionary with the student ID of 123: Output: This guide teaches you how to access nested dictionaries in Python. Besides, you learn how to create a nested dictionary, access the elements, […]

In Python, you mainly deal with variables that are either: But when you have a function inside another function, the outer function’s variables are neither local nor global in the eyes of the inner function. These variables are called nonlocal variables in Python. If you need to work with a nonlocal variable in Python, you

Text-to-speech conversion is a technique used to generate a voice output based on text. This might be useful when you don’t want to read a document but want to listen to it instead. Also, some more advanced text-to-speech tools can be used to create a realistic voice for videos, ads, or podcasts. This guide teaches

In Python, a list is a data type in which you can store multiple items. To create a list, separate elements with commas in between square brackets. For example, here is a list of integers: To access list elements, use the square-bracket accessing operator [] with the index of the item. Also notice that the

In Python, you can place an else statement at the end of a loop. The else block only runs if a break statement was not used in the loop. For example, let’s loop through a list of numbers and break the loop if a target number is encountered: Output: The target number was not found.

In Python, you can use the map() function to apply an operation for each element of an iterable, such as a list. The map() function is a replacement for a for loop. For instance, let’s square a list of numbers using the map() function instead of a for loop: Output: The result is a new

In Python, a for loop is used for iterating over an iterable collection of values such as a list, a tuple, a dictionary, a set, or a string. The for loop uses the following syntax: Where: The for loop works such that it starts looping through the iterable and one by one assigns each element to a

Python is a flexible general-purpose programming language that is easy to learn. Furthermore, Python is relevant in almost all fields of technology and software development. You can practically build any type of software with Python. Python has been around for 30+ years and it has gained massive popularity. But how far is it going? Is
