You could use the string formatting operator for that    gt  gt  gt     2f    1 234  1 23   gt  gt  gt     2f    5 0  5 00    The result of the operator is a string  so you can store it in a variable  print etc

f-string formatting  This was new in Python 3 6 - the string is placed in quotation marks as usual  prepended with f     in the same way you would r     for a raw string  Then you place whatever you want to put within your string  variables  numbers  inside braces f some string text with a  variable  or  number  within that text  - and Python evaluates as with previous string formatting methods  except that this method is much more readable   gt  gt  gt  foobar   3 141592  gt  gt  gt  print f My number is  foobar  2f  - look at the nice rounding     My number is 3 14 - look at the nice rounding   You can see in this example we format with decimal places in similar fashion to previous string formatting methods  NB foobar can be an number  variable  or even an expression eg f  3 my func 3 14  02f    Going forward  with new code I prefer f-strings over common  s or str format   methods as f-strings can be far more readable  and are often much faster

If you actually want to change the number itself instead of only displaying it differently use format    Format it to 2 decimal places   format value    2f     example    gt  gt  gt  format 5 00000    2f    5 00
