How to Compare Text in Python

Python like other programming languages supports comparison operators. These primarily use to test the condition in the program. Here's a list of operators that you can use in python programs. Comparison operators List of operators < <= > >= == != Is is not How to use comparison operators Here, I have assigned 23 to a and 11 to b. Then, I did apply all the comparison operators. The output is self-explanatory, and If you are in doubt while programming, remember to visit this page. Examples a = 23 b = 11 print("Is a greater than b?", a > b)           #greater than print("Is a less than b?", a < b)              #less than print("Is a greater or equal to b?", a >= b)   #greater or equal print("Is a less or equal to b?", a <= b)      #less or equal print("Is a equal to b (option 1)?", a == b)         #test for equality print("Is a equal to b (option 2)?", a is b)         #test for equality print("I

Python Function Argument: How to Pass it to Decorator

A decorator is a wrapper and provides additional functionality to a function. Also, it may modify the behavior, such as changing the return type/adding new abilities. Python Decorators Precisely, it is another form of function pointers . Also, it accepts function argument, then either wraps the function or returns a new one. Moreover, it modifies the inputs/outputs supplied to it. It helps you add behavior to functions (objects) dynamically (without changing the function behavior). Function Argument Below, you will find an example of passing a function argument to a decorator. The below function modifies inputs and returns output. def to_upper(func):     text=func()     if isinstance(text,str):         return text.upper() def say():     return "welcome" def hello():     return "hello"      a = to_upper(say) print(a)  b = to_upper(hello) print(b)   Output WELCOME HELLO ** Process exited - Return Code: 0 ** Press Enter to exit terminal References How to write th
