不记得如何初始化一个数据框？试试这个：

import streamlit as st
import pandas

st.help(pandas.DataFrame)

想快速检查某个函数输出的数据类型是什么？ 试试：

import streamlit as st

x = my_poorly_documented_function()
st.help(x)

想要快速检查一个对象吗？没问题：

class Dog:
  '''A typical dog.'''

  def __init__(self, breed, color):
    self.breed = breed
    self.color = color

  def bark(self):
    return 'Woof!'


fido = Dog("poodle", "white")

st.help(fido)

如果你正在使用Magic，你可以在不输入st.help的情况下获取函数、类和模块的帮助：

import streamlit as st
import pandas

# Get help for Pandas read_csv:
pandas.read_csv

# Get help for Streamlit itself:
st
