Is there a way to program a robot with python (ex, an electric motor, control it's speed, etc)

It needs a bit more than just the motor - you need to organise some i/o
(lines that the computer can control) and some kind of interface to control
the power, and you have to put it all together - can you solder?
It may be easier to forget about the computer stuff and just use relay logic
for direction control - given that it is a DC motor that would turn the other
way, and not a universal motor (like the one in a drill, that turns the same
way given either AC or DC).
Speed control for a small motor can be accomplished by a heavy rheostat
in series with the motor.
And that should be good enough for a summer project.
On the other hand, if you (or your parents) have pots of money then
you can buy digital to analog hardware that can be used to tell a powerful
DC coupled amplifier what to do, and have a stab at programming the
But if I were you, I would do the first kind of thing, and use the rest of the
summer to soak up the sun, instead of breathing solder fumes in a basement,
or crouching over a keyboard ruining your eyes watching a screen...
