Pattern.match()
Pattern.match() is a Python method in the Regex Module category. Checks for a match at the beginning of the string (compiled regex). The syntax is Pattern.match(string, pos=0, endpos=len(string)). Returns: Match or None. A typical example: pat = re.compile(r"\d+")
pat.match("123abc") # Match at position 0. A close sibling is re.search(), which scans through the string looking for a match to the regex pattern. Returns the first match or None. A close sibling is re.match(), which checks for a match only at the beginning of the string. A close sibling is re.fullmatch(), which checks if the entire string matches the regex pattern. A close sibling is re.findall(), which returns all non-overlapping matches as a list of strings or tuples.
