What does your heights looks like?
Here is a working example
heights = [("test",3.14)]
print("%15s%.2f"%((heights[0])),end="")
So heights must be a list of tuples or lists with 2 elements.

height = (float(line[1]))
the first % formats the first value into the string and the second % formats the second value. The problem is you only have one value to format into the string (unless heights[j] is a list or tuple.
if you want heights[j to be formatted in both places, i suggest doing something like this:
print("{0}15s{0}.2f".format(heights[j]), end="")
this will replace every {0} in the string with the first argument passed to format()

but i need to round it i used before round() but the last decimal if its zero did not show eg. (1.70=1.7)

@juua if you know that the height is always one number (1.7/1.6/1.9 and not 12.5/20.2) you can cast you float to a string and check its length. if the length is 2, append a '0' to the end and then print is
