Python uses more strong rules for underscores in numerical literals. Underscores are acceptable between digits and between the base prefix and digit. For example the regular expression for hexadecimals is r'0[xX]_?[\da-fA-F]+(?:_[\da-fA-F]+)[lL]?'. Underscores also are acceptable in the exponent of float literals: Exponent = r'[eE][-+]?\d+(?:_\d+)'
