![]() ![]() As you can notice, the substring till the newline ( \n) is returned because the DOT character matches any character except the new line. Next, we used the group() method to see the result. This means that we are looking to match a sequence of at least one character except for the new line. The plus sign is the repetition operator in regular expressions, and it means that the preceding character or pattern should repeat one or more times. So here, I used the search() method to search for the pattern specified in the first argument. # dot(.) metacharacter to match any character Let’s write a basic pattern to verify that the DOT matches any character except the new line. Any character means letters uppercase or lowercase, digits 0 through 9, and symbols such as the dollar ($) sign or the pound (#) symbol, punctuation mark (!) such as the question mark (?) commas ( ,) or colons (:) as well as whitespaces. Inside the regular expression, a dot operators represents any character except the newline character, which is \n. For example, (abc) will match to substring 'abc' ![]() Matches whatever regular expression is inside the parentheses. Matches any single character not in brackets. For example, If you are searching for one of the special characters you can use a \ to escape them ![]() Use to escape special characters or signals a special sequence. For example, P1|P2, where P1 and P2 are two different regexes. For example, will match either a, or, b, or c character Matches any single character in brackets. Match 1 or more repetitions of the regex. Matches 0 or more repetitions of the regex. Matches pattern only at the start of the string. Metacharacters also called as operators, sign, or symbols.įirst, let’s see the list of regex metacharacters we can use in Python and their meaning. For example, ^ (Caret) metacharacter used to match the regex pattern only at the start of the string. Characters or sign like |, , or *, are special characters. In Python, Metacharacters are special characters that affect how the regular expressions around them are interpreted. What is Metacharacter in a Regular Expression? Escape special character using a backslash (\).caret ( ^ ) to match a pattern at the beginning of each new line.What is Metacharacter in a Regular Expression?. ![]()
