Yes, use string formatting. It gives you much more control over the
content of your string including field width, number of decimal places,
justification, etc.
For example in your case:
print("Your number %d/%d is approximately %d/%d" % (numerator,
denominator,
fractions[ranges[i][0]][0],
fractions[ranges[i][0]][1]))
The stacked layout is of course optional, I just think it looks clearer.
See the thread on TimesTable for more on formatting and look at
the documentation :
https://docs.python.org/3/library/stdtypes.html#old-string-formatting
and
https://docs.python.org/3/library/string.html#formatstrings
Use whichever style you prefer.
