The format specifier inside the curly braces follows the Python format string syntax. Specifically, in this case, it consists of the following parts:
- The empty string before the colon means "take the next provided argument to
format()" – in this case thexas the only argument. - The
10.4fpart after the colon is the format specification. - The
fdenotes fixed-point notation. - The
10is the total width of the field being printed, lefted-padded by spaces. - The
4is the number of digits after the decimal point.

It has been a few years since this was answered, but as of Python 3.6 (PEP498) you could use the new f-strings:
numbers = [23.23, 0.123334987, 1, 4.223, 9887.2]
for number in numbers:
print(f'{number:9.4f}')
