When you call a function with a yield keyword, the code in the function does not run. Instead, a generator object is created. You can store the generator object to a variable. This generator object has the ability to run the code inside the function on demand. When you invoke the generator object, Python runs […]

A Python ternary operator makes it possible to write if-else statements as simple one-liner expressions. Here’s what the syntax of a ternary operator looks like in Python. This is a complete guide to using the ternary operator in Python. You will learn why and when you should or should not use it. The theory is

Dealing with dates and times in Python programs is common. You might need to write programs that deal with dates, times, or both. Besides, you commonly want to format these dates differently, build them from strings, and calculate time differences.

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
