Note that this does not change the original string, but instead outputs a new string with the changes. Finally, we used the split method with a space delimiter to create a list out of our string. We will use this again later in the chapter when parsing input from the network. TIP To ...

Testing boils down to comparing an observed value with an expected one to check if they’re equal or not. This kind of check perfectly fits into assertions. Assertions must check for conditions that should typically be true, unless you have a bug in your code. This idea is another ...
