In the below example, I am using it with a string variable and comparing it with the empty string "", similarly, you can also use it with string literals to check string equality.first="" if "" == first: print("Empty string") else: print("Not empty string") # Output: # Empty ...
To check if a string is empty or whitespace in Python, we will use the following steps. First, we will check if the string is empty using the equality operator. If the string is empty, we will print so. Otherwise, we will invoke the strip() method on the string. If the strip()...
The original and reversed strings are then compared for palindromic equality. The code proceeds to check if the original string(str(word))is equal to the reversed string("".join(reversed(word))). If the condition is met, the string is identified as a palindrome, andPalindromeis printed; oth...
Another option for checking set equality is using the all() function. This will compare each element in one set with its corresponding element in the other set and return True only if all of them match exactly. The third way to check if two sets are equal is by using issubset(). This...
You can use the in and not in operators with strings when you need to figure out if a given character is present in the target string. For example, say that you’re using strings to set and manage user permissions for a given resource:Python >>> class User: ... def __init__(...
4. Using Equality Operator == The equality operator == is another way to check if variable is None in Python, but it is not recommended. Using the is keyword 1 2 3 4 5 x = None if(x == None): print("x is of the 'None' type.") Output: x is of the ‘None’ type. ...
To check for identical values, will iterate both the lists of tuples and check for their equality. In Python, some methods directly perform this task. Method 1: One method that can accomplish that task is using the equality operator'=='.It returns a boolean value based on the equality of...
While checking for equality, the algorithm considers all zero values equal, regardless of sign. ( -0, +0 are all considered to be equal to 0), butfalseis not equal to 0. It uses thesameValueZeroalgorithm for searching whether an element is present in the array. ...
Move the pointers inward, checking for character equality ? while (left < right) { left++; right--; } Example Below is an example to find if the string is a palindrome using the Two-Pointer Technique ? Open Compiler function isPalindromeTwoPointer(str) { // Remove punctuation, spaces, an...
