How Do You Print The Output This [6,4,2,0] In A Single Row Rather That Sequence

I am using the below manual method which happens to find the high bits =1 of the binary value for a given integer. For eg: when we enter 85, the 6th, 4th, 2nd and 0th bit are high

Solution 1:

I find your recursion a bit confusing, but it can work:

def high_bit(num, lst=None):
    if lst == None:
        toplevel = True
        lst = []
    else:
        toplevel = False
    for i in range(0,100):
        if (num/(pow(2,i)))==1: 
            lst.append(i)
            num = (num - (pow(2,i)))
            high_bit(num, lst)
    if toplevel:
        print lst

high_bit(85) # prints [6, 4, 2, 0]

I would recommend doing it iteratively, though.
