When dealing with multiple conditions that need to be evaluated, Python’sif-elif-elsestructure is particularly useful. Theelifclause (short for “else if”) allows you to specify additional conditions to check if the initialifcondition is not met. This enables a more structured and efficient way...
Now let me add a way to delegate stuff based on URLs. def __iter__(self): path = self.environ['PATH_INFO'] if path == "/": return self.GET_index() elif path == "/hello": return self.GET_hello() else: return self.notfound() def GET_index(self): status = '200 OK' resp...
So far, we have presented a Boolean option for conditional statements, with eachifstatement evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif....

elif choice == 'optionC': print(1.75) elif choice == 'optionD': print(2.5) else: print(3.25) In traditional if-else statements we enclose the default option (i.e. the option that should be selected when the value of the variable does not match any of the available options) in the...

In this tutorial, you'll learn how to remove or replace a string or substring. You'll go from the basic string method .replace() all the way up to a multi-layer regex pattern using the sub() function from Python's re module.
Python doesn’t support switch-case statements. There was a proposal to introduce Python switch case statements inPEP-3103but it was rejected because it doesn’t add too much value. We can easily implement switch-case statements logic using theif-else-elif statements. However, we can implement...
