'^'cursive_re.end_of_lineMatches the end of a line.Examples:>>> str(end_of_line())
'$'cursive_re.anythingMatches any character.Examples:>>> str(anything())
'.'cursive_re.literalInserts a literal regular expression.Examples:>>> str(literal(r"\A\w"))
'\\A\\w'cursive_re.textMatches the given string exactly, escaping any special characters.Examples:>>> str(text("abc"))
'abc'cursive_re.any_ofMatches any of the given characters.Examples:>>> str(any_of("ab"))
'[ab]'

>>> str(any_of(text("ab")))
'[ab]'

>>> str(any_of(text("[]")))
'[\\[\\]]'cursive_re.none_ofMatches none of the given characters.Examples:>>> str(none_of("ab"))
'[^ab]'

>>> str(none_of(text("ab")))
'[^ab]'

>>> str(none_of(text("[]")))
'[^\\[\\]]'cursive_re.in_rangeMatches a character in the given range.Examples:>>> str(in_range("a", "z"))
'a-z'cursive_re.zero_or_moreMatches zero or more of the given expr.Examples:>>> str(zero_or_more("a"))
'(?:a)*'

>>> str(zero_or_more(text("a")))
'(?:a)*'

>>> str(zero_or_more(text("abc")))
'(?:abc)*'

>>> str(zero_or_more(group(text("abc"))))
'(abc)*'cursive_re.one_or_moreMatches one or more of the given expr.Examples:>>> str(one_or_more("a"))
'(?:a)+'

>>> str(one_or_more(text("a")))
'(?:a)+'

>>> str(one_or_more(group(text("abc"))))
'(abc)+'cursive_re.maybeMatches an expr if present.Examples:>>> str(maybe("abc"))
'(?:abc)?'

>>> str(maybe(text("abc")))
'(?:abc)?'

>>> str(maybe(group(text("abc"))))
'(abc)?'

>>> str(maybe(any_of("abc")))
'[abc]?'cursive_re.repeatedMatches an expr repeated an exact number of times.Examples:>>> str(repeated("a", exactly=5))
'(?:a){5}'

>>> str(repeated(text("a"), exactly=5))
'(?:a){5}'

>>> str(repeated(text("a"), at_least=1))
'(?:a){1,}'

>>> str(repeated(text("a"), at_most=5))
'(?:a){0,5}'

>>> str(repeated(text("a"), at_least=2, at_most=5, greedy=False))
'(?:a){2,5}?'cursive_re.groupDenotes a group whose contents can be retrieved after a match
is performed.Examples:>>> str(group(text("a")))
'(a)'

>>> str(group(any_of("abc"), name="chars"))
'(?P<chars>[abc])'
