Data within literal curly brackets using Python format()

In current Python syntax, the format() command for strings inserts data inside of curly brackets in a string:

1
2

>>> 'Insert five here: {}.'.format(5)
'Insert five here: 5.'

If you want literal brackets in a string modified by format(), you have to escape the brackets by doubling them:

1
2

>>> 'Here is what brackets look like: {{}}.'.format()
'Here is what brackets look like: {}.'

To place data inside of literal brackets, you need triple brackets — double-escaped brackets for the literal brackets and then another pair of brackets as the socket for the data:

1
2

>>> 'Now put five inside of brackets: {{{}}}.'.format(5)
'Now put five inside of brackets: {5}.'
