A generator function in Python is defined like a normal function, but whenever it needs to generate a value, it does so with the yield keywordrather than return. If the body of a def contains yield, the function automatically becomes a Python generator function.
Python Generator functions return a generator object that is iterable, i.e., can be used as an Iterator. Generator objects are used either by calling the next method of the generator object or using the generator object in a “for in” loop. Example: In this example, we will create a simple generator function in Python to generate objects using the n...
In Python, generator expression is another way of writing the generator function. It uses the Python list comprehensiontechnique but instead of storing the elements in a list in memory, it creates generator objects.

May 20, 2018 · Instead of creating a function which returns a list of values, one can write a generator which generates the values on the fly. This means that no list needs to be constructed, meaning that the resulting code is more memory efficient.
Create Python Generator. In Python, similar to defining a normal function, we can define a generator function using the def keyword, but instead of the return statement we use the yield statement. def generator_name(arg): # statements yield something. Here, the yield keyword is used to produce a value from the generator.

Feb 5, 2024 · Python | Generator Expressions. In Python, to create iterators, we can use both regular functions and generators. Generators are written just like a normal function but we use yield () instead of return () for returning a result. It is more powerful as a tool to implement iterators.
