Uso específico del módulo de vista de línea de comandos de Python

Generalmente, si está en Windows y ha instalado el entorno de desarrollo integrado Pycharm, no existe tal problema (Ctrl + clic del mouse en el nombre del objeto, puede ver directamente el uso de funciones específicas). Tome el módulo de terceros prettytable como ejemplo:

import prettytable as pt

# 按行添加数据
tb = pt.PrettyTable()
tb.field_names = ["id", "name", "phone", "age", "sex", "description"]
tb.add_row([1, "zhangsan", "132****2889", 25.23, "M", "NoDesc"])
tb.add_row([3, "lisi",     "152****7873", 18, "F", "None"])
tb.add_row([5, "wangwu",   "136****2908", 25, "M", "Nothing"])
tb.add_row([10,"zhaoliu",  "138****5322", 15, "M", "Nothing"])

print(tb)
# 按列添加数据
create_time = ["2020-11-30 20:03:07", "2020-11-30 20:08:33", "2020-11-30 20:10:11", "2020-11-30 20:12:11"]
tb.add_column("create_time", create_time)
print(tb)

# prettytable.py

class PrettyTable(object):

    def __init__(self, field_names=None, **kwargs):

        """Return a new PrettyTable instance

        Arguments:

        encoding - Unicode encoding scheme used to decode any encoded input
        field_names - list or tuple of field names
        fields - list or tuple of field names to include in displays
        start - index of first data row to include in output
        end - index of last data row to include in output PLUS ONE (list slice style)
        header - print a header showing field names (True or False)

...

También puede recordar de forma inteligente al módulo qué funciones se pueden llamar y los parámetros que se pueden configurar: 

¿Y si está en la línea de comandos? ¿Hay alguna forma de comprobarlo? (¡Por supuesto que los hay! No olvides la función de ayuda)
