Now inside the while infinite loop there is for and everytime inside for "i" iteration starts over from "0" ideally "i" should get the incremented value and start from 2, output is: So the point is "i" value is not saved and every time loop starts from 0, So how can i make "i" to start from the last incremented value before entering to for loop. while i < end: if i==5 : i = next(b) It can be both negative and positive, but not zero: range (begin,end, step) Example with step: list(range(4, 50, 5)) OUTPUT: [4, 9, 14, 19, 24, 29, 34, 39, 44, 49] It can be done backwards as well: list(range(42, -12, -7)) OUTPUT: [42, 35, 28, 21, 14, 7, 0, -7] This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.

Find centralized, trusted content and collaborate around the technologies you use most. current iteration of the loop, and continue with the next: The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and ends at a specified number. so i'm setting up an epoch as the refernce to do all the calculations. An integer number In the provided code when you try to use i in a for loop with range, it always changes to the number provided by range in the function without bothering to In this Python Tutorial, we learned how to use for loop with range() function, to loop through an iterable, and increment in steps. This function allows you to specify three parameters: start, stop, and step. Example 1: Lets use the Python NumPy arange() function to generate a range of float values by specifying only start and stop parameters. this might be an x y problem: im not sure why you wouldnt just process your list better before you iterate over it. else block: The "inner loop" will be executed one time for each iteration of the "outer It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions.
