How can it happens?

If a match found in the string then the match() function will return an object representing the match. The match is a string, am i right ? How a string can be an object?

Amit Ranjan Sahoo In low-level languages like 'C', there is no data-type known as a 'string'; they're just represented as an array of characters, which is what it actually is. In Python, 'str' is a class (a variable that stores the reference to the string-class, accurately speaking). This class includes all the string properties and methods like __class__, isalpha(), etcetera along with the character array which makes up the string (a lot more are there). Whenever a string is created, an instance of this class is made in the heap and the reference to it returned. Everything is an object in Python. P.S. I guess that the real question was to know what the match function returns. It returns a match object, btw.

Amit Ranjan Sahoo The "match object" is NOT a string. Rather it's an instance of the Match class: https://docs.python.org/3/library/re.html#match-objects You can see this better in a simple example: https://code.sololearn.com/coW3Ue21BrNk/?ref=app

Amit Ranjan Sahoo All objects other than "", 0, [], {}, None, 0.0 and False have a boolean value of 1 (True). So, if 'adf': print("This will be printed") else: print("This won't be printed") # Hope this helps

Calvin Thomas Please tell me that if re.match() returns an object then how "If statement" is working?

Amit Ranjan Sahoo Well, since 'string' means an object in Python, yeah.
