Python Tutorial #51 - Generator in Python Programming for Beginners
In this video by Programming for beginners we will see Generator in Python Programming for Beginners, in Python tutorial for beginners series.
Python programming language is very easy to learn for students and professionals.

In Python, a generator is a function that returns an iterator that produces a sequence of values when iterated over.
Generators are useful when we want to produce a large sequence of values, but we don't want to store all of them in memory at once.

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.

Syntax
def generator_name(arg):
# statements
yield something

The yield keyword is used to produce a value from the generator and pause the generator function's execution until the next value is requested.

Example code.

Python Generator Expression
In Python, a generator expression is a concise way to create a generator object.

Syntax:
(expression for item in iterable)

Use of Python Generators
1. Easy to Implement
2. Memory Efficient
3. Represent Infinite Stream of Data

Example:
def all_even():
n = 0
while True:
yield n
n += 2
