how to round to 1 decimal place in python

1>>> x = 13.949999999999999999
2>>> x
313.95
4>>> g = float("{0:.2f}".format(x))
5>>> g
613.95
7>>> x == g
8True
9>>> h = round(x, 2)
10>>> h
1113.95
12>>> x == h
13True

1answer = str(round(answer, 2))

1>>> round(1.4756,2)
21.48
3>>> round(1.3333,2)
41.33
