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.
