如果要在另一个Python程序的内核中运行代码，最简单的方法是连接BlockingKernelManager。现在最好的例子是Paul Ivanov的vim-ipython客户端，或IPython自己的终端客户端。
要点：
一个工作示例：
在shell中，执行以下操作ipython kernel（或ipython qtconsole如果要与已经在运行的GUI共享内核，请执行以下操作）：
$> ipython kernel
[IPKernelApp] To connect another client to this kernel, use:
[IPKernelApp] --existing kernel-6759.json
这写了’kernel-6759.json’文件
然后，您可以运行此Python代码段以连接KernelManager，并运行一些代码：
from IPython.lib.kernel import find_connection_file
from IPython.zmq.blockingkernelmanager import BlockingKernelManager
# this is a helper method for turning a fraction of a connection-file name
# into a full path. If you already kNow the full path, you can just use that
cf = find_connection_file('6759')
km = BlockingKernelManager(connection_file=cf)
# load connection info and init communication
km.load_connection_file()
km.start_channels()
def run_cell(km, code):
# Now we can run code. This is done on the shell channel
shell = km.shell_channel
print
print "running:"
print code
# execution is immediate and async, returning a UUID
msg_id = shell.execute(code)
# get_msg can block for a reply
reply = shell.get_msg()
status = reply['content']['status']
if status == 'ok':
print 'succeeded!'
elif status == 'error':
print 'Failed!'
for line in reply['content']['traceback']:
print line
run_cell(km, 'a=5')
run_cell(km, 'b=0')
run_cell(km, 'c=a/b')
运行的输出：
running:
a=5
succeeded!
running:
b=0
succeeded!
running:
c=a/b
Failed!

ZeroDivisionError Traceback (most recent call last)

----> 1 c=a/b
ZeroDivisionError: integer division or modulo by zero
有关如何解释回复的更多信息，请参见消息规范。如果相关，则stdout / err和display数据将过来km.iopub_channel，您可以使用返回的msg_id将shell.execute()输出与给定执行关联。
