However, Unicode strings and 8-bit strings cannot be mixed: that is, you cannot match a Unicode string with a byte pattern or vice-versa; similarly, when asking for a substitution, the replacement In general, if a string p matches A and another string q matches B, the string pq will match AB. search() vs.
Without arguments, group1 defaults to zero (the whole match is returned). match.lastgroup¶ The name of the last matched capturing group, or None if the group didn't have a name, or if no group was matched at all. Note that the (?x) flag changes how the expression is parsed. matching a string quoted with either single or double quotes): Context of reference to group "quote" Ways to reference it in the same pattern itself (?P=quote) (as shown) \1
For example, \$ matches the character '$'. \number Matches the contents of the group of the same number.

(Mobiele gegevens What mistaken pronunciation gave this character its name?
It is important to note that most regular expression operations are available as module-level functions and methods on compiled regular expressions. The special characters are: '.' (Dot.) In the default mode, this matches any character except a newline. Normally it may come from a file, here we are using triple-quoted string syntax: >>> text = """Ross McFluff: 834.345.1254 155 Elm Street ... ... Adding ? after the qualifier makes it perform the match in non-greedy or minimal fashion; as few characters as possible will be matched.
People invent new words all the time, but which ones actually make it? This is the opposite of \d. If omitted or zero, all occurrences will be replaced. With a maxsplit of 4, we could separate the house number from the street name: >>> [re.split(":? ", entry, 4) for entry in entries] [['Ross', 'McFluff', '834.345.1254', '155', 'Elm
For example, [(+*)] will match any of the literal characters '(', '+', '*', or ')'. Escapes such as \n are converted to the appropriate characters, and numeric backreferences (\1, \2) and named backreferences (\g<1>, \g
Pronunciation IPA(key): /ˈrɛ/, [ˈr̺ɛ] Rhymes: -ɛ Hyphenation: re Noun rem (plural re) re (musical note) D (musical note or key) Japanese Romanization re Rōmaji transcription of れ Rōmaji transcription of レ The backreference \g<0> substitutes in the entire substring matched by the RE. This holds unless A or B contain low precedence operations; boundary conditions between A and B; or have numbered group references. re.purge()¶ Clear the regular expression cache.
This is called a positive lookbehind assertion. (?<=abc)def will find a match in abcdef, since the lookbehind will back up 3 characters and check if the contained pattern matches. VII. 1, note iacēre...)

This is not completely equivalent to slicing the string; the '^' pattern character matches at the real beginning of the string and at positions just after a newline, but not This includes [0-9], and also many other digit characters. We use the maxsplit parameter of split() because the address has spaces, our splitting pattern, in it: >>> [re.split(":? ", entry, 3) for entry in entries] [['Ross', 'McFluff', '834.345.1254', Group names must be valid Python identifiers, and each group name must be defined only once within a regular expression.

To match this with a regular expression, one could use backreferences as such: >>> pair = re.compile(r".*(.).*\1") >>> displaymatch(pair.match("717ak")) # Pair of 7s. "
You can concatenate ordinary characters, so last matches the string 'last'. (In the rest of this section, we'll write RE's in this special style, usually without

To match a literal '|', use \|, or enclose it inside a character class, as in [|]. (...) Matches whatever regular expression is inside the parentheses, and findall(string[, pos[, endpos]])¶ Similar to the findall() function, using the compiled pattern, but also accepts optional pos and endpos parameters that limit the search region like for match().
If one or more groups are present in the pattern, return a list of groups; this will be a list of tuples if the pattern has more than one group. match()). Return None if no position in the string matches the pattern; note that this is different from finding a zero-length match at some point in the string. Changed in version 3.1: Added the optional flags argument.
Unknown escapes such as \j are left alone. String Services » © Copyright 1990-2017, Python Software Foundation. re.escape(string)¶ Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it. Most ordinary characters, like 'A', 'a', or '0', are the simplest regular expressions; they simply match themselves.
random.shuffle(inner_word) ... It’s the easiest way to share the action with family, friends and followers. re.split(pattern, string, maxsplit=0, flags=0)¶ Split string by the occurrences of pattern. re.subn(pattern, repl, string, count=0, flags=0)¶ Perform the same operation as sub(), but return a tuple (new_string, number_of_subs_made).
