The match object contains the 2-tuple span that indicates the start and end position of the match and the matched content like match = '3'.īool() function could cast the re.search result from the match object or None to True or False.

Re.search(r'\d', string) pattern scans the string and returns the match object for the first location that matches the given pattern - \d that means any number between 0 and 9 and returns None if no match is found. Use re.search(r'\d') to Check Whether a String Contains a Number Therefore, we could rewrite the above solution to, any(map(str.isdigit, stringExample)) Python map(function, iterable) fuction applies function to every element of the given iterable and returns an iterator that yields the above result. Use the map() Function to Check Whether a String Contains a Number Python Program to Check a String and Number is Palindrome Or Not True Print(any(chr.isdigit() for chr in str3)) Print(any(chr.isdigit() for chr in str2)) Print(any(chr.isdigit() for chr in str1))

CONVERT STRING TO NUMBER PYTHON WITHOUT BUILTIN CODE

If stringExample contains at least a number, then the above code returns True because chr.isdigit() for chr in stringExample has at least one True in the iterable. any(chr.isdigit() for chr in stringExample) Str.isdigit() returns True if all the characters in the given string are digits, False otherwise. Python any Function With str.isdigit to Check Whether a String Contains a NumberĪny function returns True if any element of the given iterable is True otherwise, it returns False. Python regular expression search method with pattern r'\d' could also return True if the given string contains a number. Python built-in any function together with str.isdigit will return True if the given string contains a number in it otherwise, it returns False.
