Error in a file and problem with ptpython

[Gribouillis]

Second trouble: this code uses a module timer which we don't know where it comes from. However, I suspect it is this module from the cheeseshop, which runs this C code. As you can see in function Timer_new(), it takes at least 2 arguments: a time in microseconds and a python callback.

It is also possible that from timer import Timer invokes a different module on the author's computer and this timer module on yours, which would explain the error.
