Compile a regular expression pattern, returning a pattern object.

Return the string obtained by replacing the leftmost
non-overlapping occurrences of the pattern in string by the
replacement repl.  repl can be either a string or a callable;
if a string, backslash escapes in it are processed.  If it is
a callable, it's passed the match object and must return
a replacement string to be used.

Scan through string looking for a match to the pattern, returning
a match object, or None if no match was found.

Try to apply the pattern at the start of the string, returning
a match object, or None if no match was found.

int(x[, base]) -> integer

Convert a string or number to an integer, if possible.  A floating point
argument will be truncated towards zero (this does not include a string
representation of a floating point number!)  When converting a string, use
the optional base.  It is an error to supply a base when converting a
non-string.  If base is zero, the proper base is guessed based on the
string content.  If the argument is outside the integer range a
long object will be returned instead.

Escape all non-alphanumeric characters in pattern.

Return a list of all non-overlapping matches in the string.

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.

Empty matches are included in the result.

Split the source string by the occurrences of the pattern,
returning a list containing the resulting substrings.

Return an iterator over all non-overlapping matches in the
string.  For each match, the iterator returns a match object.

Empty matches are included in the result.

Return a 2-tuple containing (new_string, number).
new_string is the string obtained by replacing the leftmost
non-overlapping occurrences of the pattern in the source
string by the replacement repl.  number is the number of
substitutions that were made. repl can be either a string or a
callable; if a string, backslash escapes in it are processed.
If it is a callable, it's passed the match object and must
return a replacement string to be used.
