pdb.runeval(expression, globals=None, locals=None) Evaluate the expression (given as a string or a code object) under debugger control. When runeval() returns, it returns the value of the expression. Otherwise this function is similar to run().

starmap(func, iterable[, chunksize]) Like map() except that the elements of the iterable are expected to be iterables that are unpacked as arguments. Hence an iterable of [(1,2), (3, 4)] results in [func(1,2), func(3,4)]. New in version 3.3.

install_scripts(context, path) path is the path to a directory that should contain subdirectories “common”, “posix”, “nt”, each containing scripts destined for the bin directory in the environment. The contents of “common” and the directory corresponding to os.name are copied after some text replacement of placeholders: __VENV_DIR__ is replaced with the absolute path of the environment directory. __VENV_NAME__ is replaced with the environment name (final path segment of environment directo

ArgumentParser.add_mutually_exclusive_group(required=False) Create a mutually exclusive group. argparse will make sure that only one of the arguments in the mutually exclusive group was present on the command line: >>> parser = argparse.ArgumentParser(prog='PROG') >>> group = parser.add_mutually_exclusive_group() >>> group.add_argument('--foo', action='store_true') >>> group.add_argument('--bar', action='store_false') >>> parser.parse_args(['--foo
