The Pythonlen()is used to get the total number of characters present in the string and check if the length of the string is 0 to identify the string is empty. Actually, thelen()function returns the length of an object. The object can be a string, a list, a tuple, or other objects ...
# Python program to check if a string is # palindrome or not # function to check palindrome string def isPalindrome(string): rev_string = string[::-1] return string == rev_string # Main code x = "Google" if isPalindrome(x): print(x,"is a palindrome string") else: print(x,"is...
Thefloat()function can be used to check if a string is a floating-point number in Python, actually, this method converts a string to a floating-point number however, we can use this to check string contains a float value. When passed a string that cannot be converted to a float, it ...
Check if a String is Empty or Whitespace in Python Using the Equality Operator To check if a string is empty using the equality operator, we can just compare the string with another empty string. If the result is True, the input string is empty. Otherwise not. input_string="" print("Th...
Python Data TypesUsing float() def isfloat(num): try: float(num) return True except ValueError: return False print(isfloat('s12')) print(isfloat('1.123')) Run Code Output False True Here, we have used try except in order to handle the ValueError if the string is not a float. In th...

One easy way to check if a Python string is in CamelCase is to use the “re” (regular expression) module. We will import this module, construct a suitable pattern, and use the match() function in “re” to detect if the input string matches the pattern.Here...
In this tutorial, we'll take a look at how to check if a variable is a string in Python, using the type() and isinstance() functions, and the is operator.
