The function block begins with the"def"keyword and"function_name". In the parenthesis, it may have an argument or not. Now, let's start to create a function in Python that returns the integer obtained by reversing the digits. Before going to solve the above problem, assume the name of ...
To check if an element exists in the list using the "in" statement in Python, you simply use the "in" keyword followed by the element you are searching for and the list. This method performs a linear search across the list and returns True if the element is found, making it highly ...
print(f"The input contains the keyword '{keyword}'") else: print(f"The input does not contain the keyword '{keyword}'") In this scenario, we have auser_inputstring representing a user’s input, and we want to check if it contains thekeyword“apple” regardless of the case. By conver...
