Errata: page 237


There should be no space between “…command:” and “move”.

Enter your command:move east
or it shows the commandnotfound error message.


Are you sure? When you add the line to elicit input on page 224, a trailing space is included in the string printed out:

print("> Enter your command: ")

I had no space between “:” and “*”.

print("> Enter your command:")

It worked as described in the book, when I added a space.

print("> Enter your command: ")

Thanks for clarifying.


Nice! Thanks for reaching out.
