Python string formatting - limit string length, but trim string beggining -



Python string formatting - limit string length, but trim string beggining -

i'm using python standard logging module custom formatter limit length of fields. uses standard % python operator.

i can apply limit percent-formatted string (this limits length 10 chars):

>>> "%.10s" % "lorem ipsum" 'lorem ipsu'

is possible trim beginning, output 'orem ipsum' (without manipulating right-side argument)?

python's % formatting comes c's printf.

note . indicates precision float. works on string mere side effect, , unfortunately, there no provision in string formatting specification accommodate stripping string left fixed max width.

therefore if must strip string fixed width end, recommend piece negative index. operation robust, , won't fail if string less 10 chars.

>>> up_to_last_10_slice = slice(-10, none) >>> 'lorem ipsum'[up_to_last_10_slice] 'orem ipsum' >>> 'ipsum'[up_to_last_10_slice] 'ipsum'

python string
