If you want to run the Python Debugger $($pdb$)$ from the Python Shell, which two statements in the shell would you use?

$>>>$ import pdb $>>>$ pdb$.$start$(\text{'}$script name'$)$

$>>>$ import pdb $>>>$ pdb$(\text{'}$script name'$)$

$>>>$ import pdb $>>>$ pdb$.$run$(\text{'}$script name'$)$

$>>>$ import pdb $>>>$ pdb$.$trace$(\text{'}$script name'$)$

$>>>$ import pdb $>>>$ pdb$($script name$)$
