- re — Regular expression operations — Python 3. 13. 5 documentation
{m} Specifies that exactly m copies of the previous RE should be matched; fewer matches cause the entire RE not to match For example, a{6} will match exactly six 'a' characters, but not five {m,n} Causes the resulting RE to match from m to n repetitions of the preceding RE, attempting to match as many repetitions as possible For example, a{3,5} will match from 3 to 5 'a' characters

A backreference to the whole match value is \g<0>, see re sub documentation: The backreference \g<0> substitutes in the entire substring matched by the RE See the Python demo :

10 {m, n} - Braces Braces match any repetitions preceding regex from m to n both inclusive For example - a{2, 4} will be matched for the string aaab, baaaac, gaad, but will not be matched for strings like abc, bc because there is only one a or no a in both the cases 11 (<regex>) - Group Group symbol is used to group sub-patterns For

Character(s) What it does A period Matches any single character except the newline character ^ A caret Matches a pattern at the start of the string
- python regex: what does the (?P lt;name gt;. . . ) mean
From the re module documentation: (?P<name> ) Similar to regular parentheses, but the substring matched by the group is accessible via the symbolic group name name Group names must be valid Python identifiers, and each group name must be defined only once within a regular expression

re Match object: details like matched portions, location, etc; m[0] or m group(0) entire matched portion of re Match object m; m[n] or m group(n) matched portion of the nth capture group; m groups() tuple of all the capture groups' matched portions; m span() start and end+1 index of the entire matched portion; pass a number to get span of that
- re — Regular expression operations - Python 3. 7. 3 Documentation
Scan through string looking for the first location where the regular expression pattern produces a match, and return a corresponding match object 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 re match (pattern, string, flags=0)
- Regular Expression HOWTO — Python 3. 11. 12 documentation
match() and search() return None if no match can be found If they’re successful, a match object instance is returned, containing information about the match: where it starts and ends, the substring it matched, and more You can learn about this by interactively experimenting with the re module If you have tkinter available, you may also want to look at Tools demo redemo py, a
