If numbers, they width will always be the same size as the data to fill it, so well. In the second statement, you can see the width (2) is less than the number (1234), so it doesn't take any space to the left but also doesn't truncate the number. side effects are both rare and strongly discouraged by the Finally, lets print a floating point number which truncates after three decimal places but does round the final value. implemented in C) may not be the one presented here. vformat is the function that does the actual work of formatting. Putting the complete formatstring into parenthesis before applying .format to it fixes that. formatting is explicitly invoked, that less care needs to be width is a decimal integer defining the minimum field width. a mechanism which, like %, is efficient for small strings The rules for parsing an item key are very simple. with the different versions of Python, such a capability will not You can see that the box length for printing the string is 10. older system. The following will generate the same output as above: Both sets of formatting directives allocate 8 spaces for your number, format it as a float with 2 digits after the decimal point. It is because the alignment can only occur in a box of fixed length. Also, try to get used to string formatting in python instead of just concatenating strings.
