This approach is correct and perfectly fits the time. My solution with the same approach took 2273ms to execute all the tests.

Python. v1, functions like:

def mov(params):
	...
eval(fn_name+'params')

12+s on the second test. Timeout.

v2, bunch of ifs:

if cmd == 'mov':
	...
elif ...

0.6+s. Passed.

Similar story. Python. For random tests fails with [X] should equal [X, X]. Can't get it.
