I tried to execute problem code from tabnanny in PyCharm - that's ok
from test.support import (captured_stderr, captured_stdout, script_helper, findfile, unlink)


def validate_cmd(self, *args, stdout="", stderr="", partial=False):
    """Common function to assert the behaviour of command line interface."""
    _, out, err = script_helper.assert_python_ok('-m', 'tabnanny', *args)
    # Note: The `splitlines()` will solve the problem of CRLF(\r) added
    # by OS Windows.
    out = out.decode('ascii')
    err = err.decode('ascii')
    if partial:
        for std, output in ((stdout, out), (stderr, err)):
            _output = output.splitlines()
            for _std in std.splitlines():

        self.validate_cmd(stderr=stderr)
