一般如果在 Windows 的话，而且你还安装了 Pycharm 集成开发环境的话，是没有这个困扰的（Ctrl + 鼠标点击 对象名，就直接可以查看具体函数的使用方法了）。以第三方模块 prettytable 为例：

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)...

还可以智能提示模块有哪些可以调用的函数以及可以的设置参数： 

如果是在命令行的怎么办？有没有可以查看的方法呢？（当然是有的啦！不要忘记 help 的作用哟）
