ipython笔记本中的自定义魔术-代码不执行

我对ipython magics比较陌生，希望运行一些代码，同时通过magic命令将其添加到列表中。魔法的定义如下

#iPython notebook magic
from IPython.core.magic import  (
    Magics, magics_class, cell_magic, line_magic
)

@magics_class
class ReportMagic(Magics):
    def __init__(self, shell,  data):
        super(ReportMagic,self).__init__(shell)
        self._code_store = []
        self._markdown_store = []
        self._conf_code_store=[]
        self._conf_markdown_store=[]
        self.data = data
        # inject our store in user availlable namespace under __mystore
        # name
        shell.user_ns['__mycodestore'] = self._code_store
        shell.user_ns['__mymarkdownstore'] = self._markdown_store

    @cell_magic
    def add_code_to_report(self, line, cell):
        """store the cell in the store"""
        self._code_store.append(cell)

    @cell_magic
    def add_markdown_to_report(self, line, cell):
        """store the cell in the store"""
        self._markdown_store.append(cell)

    @cell_magic
    def add_conf_code_to_report(self, line, cell):
        """store the cell in the store"""
        self._conf_code_store.append(cell)

    @cell_magic
    def add_conf_markdown_to_report(self, line, cell):
        """store the cell in the store"""
        self._conf_markdown_store.append(cell)


    @line_magic
    def show_report(self, line):
        """show all recorded statements"""
        return self._conf_markdown_store,self._conf_code_store ,self._markdown_store,self._code_store

# This class must then be registered with a manually created instance,
# since its constructor has different arguments from the default:
ip = get_ipython()
magics = ReportMagic(ip, 0)
ip.register_magics(magics)

%%add_conf_code_to_report

import pandas as pd
import numpy as np
import os
import collections

我给魔术师打电话如下

#iPython notebook magic
from IPython.core.magic import  (
    Magics, magics_class, cell_magic, line_magic
)

@magics_class
class ReportMagic(Magics):
    def __init__(self, shell,  data):
        super(ReportMagic,self).__init__(shell)
        self._code_store = []
        self._markdown_store = []
        self._conf_code_store=[]
        self._conf_markdown_store=[]
        self.data = data
        # inject our store in user availlable namespace under __mystore
        # name
        shell.user_ns['__mycodestore'] = self._code_store
        shell.user_ns['__mymarkdownstore'] = self._markdown_store

    @cell_magic
    def add_code_to_report(self, line, cell):
        """store the cell in the store"""
        self._code_store.append(cell)

    @cell_magic
    def add_markdown_to_report(self, line, cell):
        """store the cell in the store"""
        self._markdown_store.append(cell)

    @cell_magic
    def add_conf_code_to_report(self, line, cell):
        """store the cell in the store"""
        self._conf_code_store.append(cell)

    @cell_magic
    def add_conf_markdown_to_report(self, line, cell):
        """store the cell in the store"""
        self._conf_markdown_store.append(cell)


    @line_magic
    def show_report(self, line):
        """show all recorded statements"""
        return self._conf_markdown_store,self._conf_code_store ,self._markdown_store,self._code_store

# This class must then be registered with a manually created instance,
# since its constructor has different arguments from the default:
ip = get_ipython()
magics = ReportMagic(ip, 0)
ip.register_magics(magics)

%%add_conf_code_to_report

import pandas as pd
import numpy as np
import os
import collections

导入代码被复制到_conf_code_存储区，但我无法从导入的库调用函数。

---

我希望代码应该被添加到_conf_code_store中，同时导入的库功能应该可以在笔记本中使用。

我已经能够找到解决方法。 要通过magic函数执行代码，必须为ipython对象调用run_单元实例。有更好的方法可以做到这一点，但代码目前仍然有效

@cell_magic
@needs_local_scope
def add_conf_code_to_report(self, line, cell):
    """store the cell in the store"""
    self._conf_code_store.append(cell)
    print type(cell)
    exec 'from IPython.core.display import HTML'
    for each in cell.split('\n'):
        print each
        exec repr(each.strip())
    ip=get_ipython()
    ip.run_cell(cell)
