You wrote about 140 or more lines, but didn&#x
mark which rows are to be used for which purpose. Later,
when using the data, you include a CONDITION that row X is true, or
whatever.

data and reserved data.

ne language to be able to do what the other does, in some cases.
And, amusingly, much of the underlying functionality accessed is in C or C++
with some data structures being translated to/from the compiled C/C++
equivalents as you enter a function, them translated back at exit.
This is not very deep

In Python, it is traditional to use "self" rather
id something similar to many of the
methods that now return None, you could use the new class when needed.
This seems too simple so it must have been done. Obviously not in the
standard distribution but perhaps elsewhere. And, no, I do not expect a
method like pop() to suddenly return the list

not the object itself.
This is one of my few complaints about Python.
