However, str.format() is not without its issues. Chief among them is its verbosity. For example, the text 'value' is repeated here: >>> value = 4 * 20 >>> 'The value is {value}.'.format(value=value) 'The value is 80.' Even in its simplest form, there is a bit of boilerplate, and the value that's inserted into the placeholder is sometimes far removed from where the placeholder is situated: >>> 'The value is {}.'.format(value) 'The value is 80.' With an f-string, this becomes: >>> f'The value is {value}.' 'The value is 80.' Yeah I've had this thought before.
