def Exaple(number:int): if number == None: return ""
Here is what the above code is Doing:
1. It’s defining a function called “Exaple” that takes a single parameter called “number”.
2. It’s checking to see if the value of “number” is equal to None.
3. If the value of “number” is equal to None, the function returns an empty string.
You can use this same pattern to check for any other value that you might want to check for.
For example, let’s say you want to check to see if a list is empty. You can do that like this:
if lst == :
This function will return True if the list is empty, and False if the list is not empty.
