   How to create a one-off generator in Python?

   • When you want to create one-off generators, using a function can seem redundant. Similar to list and dictionary comprehensions, Python allows you to create generator expressions. This simplifies the process of creating generators, especially for generators that you only need to use once.

   What is the difference between a python function and a generator?

   • A very interesting difference between Python functions and generators is that a generator can actually hold more than one yield expressions! While, theoretically, a function can have more than one return keyword, nothing after the first will execute. Let’s take a look at an example where we define a generator with more than one yield statement:

   What is a Python generator?

   • Python generators provide you with the means to create your own iterator functions. These functions allow you to generate complex, memory-intensive operations. These operations will be executed lazily, meaning that you can better manage the memory of your Python program. By the end of this tutorial, you’ll have learned:

   What is a generator expression in Python?

   • In Python, a generator expression is a concise way to create a generator object. It is similar to a list comprehension, but instead of creating a list, it creates a generator object that can be iterated over to produce the values in the generator. A generator expression has the following syntax,
