When the result is longer than one line, the \"pretty printer\" adds line breaks and indentation to more clearly reveal data structure\n\n>>> import pprint >>> t = [[[['black', 'cyan'], 'white', ['green', 'red']], [['magenta', ... 'yellow'], 'blue']]] ... >>> pprint.pprint(t, width=30) [[[['black', 'cyan'], 'white', ['green', 'red']], [['magenta', 'yellow'], 'blue']]]\n\nThe textwrap module formats paragraphs of text to fit a given screen width\n\n>>> import textwrap >>> doc = \"\"\"The wrap() method is just like fill() except that it returns ... a list of strings instead of one big string with newlines to separate ... the wrapped lines.\"\"\" ... >>> print(textwrap.fill(doc, width=40)) The wrap() method is just like fill() except that it returns a list of strings instead of one big string with newlines to separate the wrapped lines.\n\nThe locale module accesses a database of culture specific data formats. The grouping attribute of locale's format function provides a direct way of formatting numbers with group separators\n\n>>> import locale >>> locale.setlocale(locale.LC_ALL, 'English_United States.1252') 'English_United States.1252' >>> conv = locale.localeconv() # get a mapping of conventions >>> x = 1234567.8 >>> locale.format_string(\"%d\", x, grouping=True) '1,234,567' >>> locale.format_string(\"%s%.f\", (conv['currency_symbol'], ... conv['frac_digits'], x), grouping=True) '$1,234,567.80'\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
