It is possible to execute them command by command,
inp = open(cmd_file)
for line in inp:
exec line
might help. You don't get quite the same feeling as
"like if the commands was typed one after the other in a interactive session", but perhaps this helps.
Warning: the code above is without any error checks.
You might also run into security problems, the example
above assumes you trust your input.
HTH. YMMV.

Try it on a file that reads something like
xxx = 42
print xxx
and you will see NameError raised because the assignment hasn't affected the environment for the print statement.
