Rookie over here... Need assistance with a Python code conclusion-CodePudding

Complete this function to return either "Hello, [name]!" or "Hello there!" based on the input

def say_hello(name):
    name = "Hello there!"

    assert name != "Hello there!"
    # You can print to STDOUT for debugging like you normally would
    print(name)

    # but you need to return the value in order to complete the challenge  
    return "" # TODO: return the correct value

I've tried a couple of things but run into errors such as assertion error... I have completed practice test similar to this before but I'm just drawing a blank here. Any help with the proper code and how you came to it would be greatly appreciated.

CodePudding user response：

This will populate the name if one is given and it is not empty ("" evaluates to False)

def say_hello(name=None):
    return f"Hello, {name}!" if name else "Hello there!"

CodePudding user response：

assert doesn't make much sense here. You just want to choose one of two return values based on the value of name. You can start with adding a default value to the name parameter which gives the caller the option of not supplying a name at all and then do a simple truth test.

def say_hello(name=None):
    if name:
        return f"Hello, {name}"
    else:
        return "Hello there!"
