Why can use python generators?

In Python blogs, we have learned about some few concepts, such as Differences between 2 & 3, Is Python is interpreted or compiled, the importance of Python and some other blogs are there. From this blog, I explained about Python generators and what are the basic terms to know about generators. With Python Generators what we can do in coding? Are there any changes take place with Generators? For all question, I am trying to explain below. As compared to other languages also Python is the best language, which can translate the code very easily. This blog explains Why can we use Python Generators? Before going to this concept, as we discussed that in my previous blogs.

Anyone can learn Python with no worries if you are in new to the Python also don’t worry. Because compared to Python 2, Python 3 is the best of new learners. I explained this concept in the previous blog. If interested go and check. Yes, with Python 3 you can learn easily, and so many advantages are there. As compared to other languages also Python is the best language, which can translate the code very easily. This blog explains Why can we use Python Generators?

Top companies are presently working with Python, let’s know what’s the importance with Python. The main benefit of Python developers are interpreters and libraries are available in free cost. This is the small overview of Python for those who are new to the Python. From this blog know the concept of Python Generators. Let’s Have a look at the title Why can we use Python Generators? on below.

Why can we use Python Generators?

Actually, this is a difficult concept in Python. But Python Generators are very powerful and easy to implement. For beginners, this concept is very difficult to understand and creating confusion. So that they can hold off this topic at until they are ready for. I think this is the unfair judgment. Learn Generators as fast as possible because this concept is most important for interviews and developing the sites also. Learn at more Python online training

What are the Generators?

Generators are used to create the iterators but in a different way. Generally, generators are the functions that can return value several times. Let’s imagine, if we define a function and we want to return a value in a couple of times what we entered into that statement. We can do this statement using normal Python and check what happens, take look on below.

def my_func(x):

return x*2

The above result shows that the function gives the value of x and it can double only once. But, we can use generators it makes double on every time when we called the next() function. This process will occur when the yield keyword come into the picture. The yield keyword is the same as the return keyword in normal Python. But, only differences is yield can call so many time as we would like. Let’s see an example, how generators will work and how it doubles the value. Have a look on below.

The above result shows whatever we gave as an input, it shows the result three times. Take a value 2 and pass it to an input and finally, it ends the result as 16. Because of three-time iteration right. Key takeaways: generators and you in below.

1. Two ways to create a generator: generator function and generator expressions.
2. In generators function, we can use yield as a keyword. And, the same way in regular functions we can use return as a keyword.
3. In generator expression, we need (), and list comprehension use [].
4. We can only use the generator once.

Generators are not a difficult topic, but people think that it’s very difficult to understand. If we give time to learn this concept then Python developers will perform well compared to before. Take a Big Data situation, the simple methods go fall down but generator analyses still stand top. There is a lot of information regarding generators but we didn’t discuss here.
