New submission from Łukasz Rekucki <[email protected]>:
The documentation states: "Most built-in types implement the following options
for format specifications, although some of the formatting options are only
supported by the numeric types."
The list doesn't include "s" presentation type, which is actually accepted for
most built-in types *except* numeric ones. So you can write:
>>> "{:s}".format([])"
'[]'
But with numeric types you have to explicitly convert:
>>> "{!s:s}".format(5)
'5'
>>> "{:s}".format(5) # fails
