how to get the index of element of the iterated list directly, without using index()? How to count the instances and not values?

In the "for" loop, does the program "know" the position of the iterated element in the list? I can't use index() method for getting the index because I have a bunch of identical ones and zeros, so I need the way of counting the instances of iterated elements, without checking their values. I think that maybe the "for" loop is already counting the instances or checking the next() element of the list, so I need to get to there. P.S. No, I don't wanna use i=0 ........ i+=1, I know it will work but for some reasons I will not P.P.S. No, dictionary won't work either

yeah. in that case you could that example of mine and use if list[i] == 1: and i instead of index

objects = [o1, o2, o3, o4, o5] #each object has its method, and I need to run those depending on the list I have here list = [1,0,1,1,1,0,1,0,1,1,1,0,1] for var in list: if var == 1: object_used = objects[list.index(var)] object_used.method() #obviously, this will not work because index() function returns the index of first "1" in the list, and I need to get the real position of var I'm checking

how? tell me how to use that, cos that doesn't sound like it will work and please don't tell me it's for I in range(list): if list[i] == 1: object = objects[i]
