Answer 1

If you want to change the actual value, use round as Eli suggested. However for many values and certain versions of Python this will not result be represented as the string “39.54”. If you want to just round it to produce a string to display to the user, you can do

>>> print "%.2f" % (39.54484700000000)
39.54

or in newer versions of Python

>>> print("{:.2f}".format(39.54484700000000))
39.54

or with the fstrings

>>> print(f'{39.54484700000000:.2f}')
39.54
