The body of if and else statements starts with indentation. Let’s see an example of the implementation of the if…else statement. Python 1 2 3 4 5 6 7 i = 20; if (i < 15): print ("i is smaller than 15") else: print ("i is greater than 15") print ("statement after if...

“If” statements go together with the “else” and “elif” statements. The “elif” statement allows you to evaluate other possible conditions after your original “if” statement returns “False” (in which it works just like an “if” statement consisting of a condition and a group of c...
This is the code I have written. It runs smoothly without the regular expressions components. However, when I replace result1 and result2 with the required extract strings , it doesn't work. Is there something I'm overlooking? I believe the '.' matches all characters after 'index1', is ...
Learn how to use if-else statements in R programming to control the flow of your code with conditional logic.
In this tutorial, we are going to learn about how to check if a string starts with another substring in Python. Python has a built-in startswith() method by using that we can check if a given string starts with another string or not. The startswith() method returns true if a string...
Test the program with different values for the variable "year" such as 1900, 2023, 2000, 2012.The same result can be achieved by using the compound Boolean expressions instead of nested if statements, as shown below −If (year % 4 == 0 && (year % 400 == 0 || year % 100 != ...
Regular expressions provide a more flexible (albeit more complex) way to check strings for pattern matching. With Regular Expressions, you can perform flexible and powerful searches through much larger search spaces, rather than simple checks, like previous ones. Python is shipped with a built-in ...
string is empty or not in Python. Since empty strings are considered as false in Python, we can directly use it on the if condition to check or use it with eithernotoperator orbool()function. And also learned to use the==operator and__eq__()to check whether strings are empty or not...
# 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...
