+++ when use yield the MAIN value of the function will be the one that assigned to yield (sq) +++when ask for the function (which main value of it is the one that assigned to yield because of yield effect) will give you the next value of the variable that assigned to yield (sq) and that was the main two features of yield

You did not explain how yield works i.e does the function just "stop" in time when it reaches yield and how does for loop know that no more yields are coming?

why we have to write 15-16 of code just to print 1--10 values. this can be easily done with the help of loops

@sourabhsharma9830 11 ай бұрын

If you have 100 TBs if data and want to reduce the data, you can use loops because of memory constraints but you can use generators to load chunks of data and reduce it one by one.

Sir I'm confused about the use of yield ,in place of that we will write return statement still it works.. please reply to my as soon as possible....

@believer2023_ 2 ай бұрын

If you write return that it's a simple function and it no longer remains a generators. Using keyword yield makes it a generator. Now when you use return it's a simple function where you can use for loop to get the values. But when you're making it a generator you can fetch values one by one because of the yield keyword. Since yield keyword has inbuilt iter() method and you don't need to define iter() method specifically. Yield generate iterator objects(values).

@dadivenkat4213 3 жыл бұрын

Hi, I have a clarification how the code worked. We just created "values" object. We didn't call any methods, but still how it is printing. Generally we have to call the method (eg:- values.__iter__() or values.__next__()) right? Is there anything like the methods declared with dunders(___x__()) will be executed automatically when you create an instance. When we gave "print(next(values))" it printed only once, where as in for loop it printed 10 times. So how the variable 'i' knows its iteration value. Can anyone help

@vojtechbrecka201 3 жыл бұрын

Hey! For loops are very cool, but you are a bit limited. With the method next() you can use the first element of your list for something, than write some lines of codes and than use the next element of your list (tuple, string...) for something different. Thi is something that cannot be done with for loop. For loop is great but only when you want to do the exact same thing with every single element of your list. I hope you can understand, sorry for my english, it is not my native language and good luck with programming!

Why do we need generator and iterator ,if we can iterate using loops

@aghilpwilson879 2 жыл бұрын

It will create memory error if we use large number to iterate...since it will first store the value..generators helps to avoid that error since it will not store the values
