If you are putting the result in a larger string, use an formatted string literal (3.6+) or use str.format() and put the second argument for the format() function after the colon of the placeholder {:..}: As it happens, even for just formatting a single value (so without putting the result in a larger string), using a formatted string literal is faster than using format(): But I'd use that only if performance in a tight loop matters, as format() communicates the intent better. It is an excellent choice and a highly recommended method in this case. It is possible to display BCD without having assign to this literal. This behavior is chosen so that the bytes of a packed struct correspond exactly to the layout in memory of the corresponding C struct. Standard size depends only on the format character; see the table in the Format Characters section. should at least explicitly contain the base in the error The buffer must contain at least the amount of data required by the format (len(buffer[offset:]) must be at least calcsize(fmt)). continue to share identical behavior. That is true only for parsing of integer literals, not for conversion of strings to ints - eg. Does Cast a Spell make you a spellcaster?

If the string passed in to pack() is too long (longer than the count minus 1), only the leading count-1 bytes of the string are stored. For the 's' format character, the count is interpreted as the size of the string, not a repeat count like for the other format characters; for example, '10s' means a single 10-byte string, while '10c' means 10 characters. The following code uses the rjust() function to display a number with leading zeros in Python.
