Hi Rafael
You are appending quit to the list, before checking to see if quit has been
typed. You could move the "if Statement" up in the code and add an else
statement, so Quit is not appended to the list first thing.
while True:
activity = input(prompt)
if activity == "quit":
print("Let me recap. This is what you've done today: %s." % ",
" .join(LogActivities))
else:
LogActivities.append(activity)
But you have an infinite loop here too, so unless you are adding more to
this, and plan to get out the loop, you should also add a break statment:
++++++++++++++++++++++++++++++++++++
if activity == "quit":
print("Let me recap. This is what you've done today: %s." % ",
" .join(LogActivities))
break ###<<<<Add a break
+++++++++++++++++++++++++++++++++++
Or change the code structure and loop condition:
+++++++++++++++++++++++++++++++++++++
LogActivities = []
prompt = ("What have you done today? "
"Enter 'quit' to exit. ")
activity = input(prompt)
while activity != "quit":
LogActivities.append(activity)
activity = input(prompt)
print("Let me recap. This is what you've done today: %s." %
",".join(LogActivities))
++++++++++++++++++++++++++++++++++++++
There's probably a more pythonistic way to write this, but without changing
the current set of statements too much, this works.
Cheers
