numeric forms (:class:`integers`, :class:`reals`, :class:`scientific notation`) - common :class:`programming identifiers` - network addresses (:class:`MAC`, :class:`IPv4`, :class:`IPv6`) - ISO8601 :class:`dates` and :class:`datetime` - :class:`UUID` - :class:`comma-separated list` - :class:`url` Parse actions: - :class:`convertToInteger` - :class:`convertToFloat` - :class:`convertToDate` - :class:`convertToDatetime` - :class:`stripHTMLTags` - :class:`upcaseTokens` - :class:`downcaseTokens` Example:: pyparsing_common.number.runTests(''' # any int or real number, returned as the appropriate type 100 -100 +100 3.14159 6.02e23 1e-12 ''') pyparsing_common.fnumber.runTests(''' # any int or real number, returned as float 100 -100 +100 3.14159 6.02e23 1e-12 ''') pyparsing_common.hex_integer.runTests(''' # hex numbers 100 FF ''') pyparsing_common.fraction.runTests(''' # fractions 1/2 -3/4 ''') pyparsing_common.mixed_integer.runTests(''' # mixed fractions 1 1/2 -3/4 1-3/4 ''') import uuid pyparsing_common.uuid.setParseAction(tokenMap(uuid.UUID)) pyparsing_common.uuid.runTests(''' # uuid 12345678-1234-5678-1234-567812345678 ''') prints:: # any int or real number, returned as the appropriate type 100 [100] -100 [-100] +100 [100] 3.14159 [3.14159] 6.02e23 [6.02e+23] 1e-12 [1e-12] # any int or real number, returned as float 100 [100.0] -100 [-100.0] +100 [100.0] 3.14159 [3.14159] 6.02e23 [6.02e+23] 1e-12 [1e-12] # hex numbers 100 [256] FF [255] # fractions 1/2 [0.5] -3/4 [-0.75] # mixed fractions 1 [1] 1/2 [0.5] -3/4 [-0.75] 1-3/4 [1.75] # uuid 12345678-1234-5678-1234-567812345678 [UUID('12345678-1234-5678-1234-567812345678')] integerz hex integerz[+-]?\d+zsigned integer/fractioncCs|d|dS)Nr)ttrr/builddir/build/BUILDROOT/alt-python38-pip-22.2.1-2.el8.x86_64/opt/alt/python38/lib/python3.8/site-packages/pip/_vendor/pyparsing/common.pyzpyparsing_common.-z"fraction or mixed integer-fractionz[+-]?(?:\d+\.\d*|\.\d+)z real numberz@[+-]?(?:\d+(?:[eE][+-]?\d+)|(?:\d+\.\d*|\.\d+)(?:[eE][+-]?\d+)?)z$real number with scientific notationnumberz[+-]?\d+\.?\d*([eE][+-]?\d+)?fnumber identifierzK(25[0-5]|2[0-4][0-9]|1?[0-9]{1,2})(\.(25[0-5]|2[0-4][0-9]|1?[0-9]{1,2})){3}z IPv4 addressz[0-9a-fA-F]{1,4} hex_integer:zfull IPv6 address)rz::zshort IPv6 addresscCstdd|DdkS)Ncss|]}tj|rdVqdS)rN)r _ipv6_partmatches).0rrrr s z,pyparsing_common...)sumtrrrrrz::ffff:zmixed IPv6 addressz IPv6 addressz:[0-9a-fA-F]{2}([:.-])[0-9a-fA-F]{2}(?:\1[0-9a-fA-F]{2}){4}z MAC address%Y-%m-%dfmtcsfdd}|S)a Helper to create a parse action for converting parsed date string to Python datetime.date Params -
