加载.py文件并显示IPython交互式外壳

Question

In a .py file, I have the following content

class Point(object):
    def __init__(self, x, y):
        self.x, self.y = x, y

p1 = Point(1, 1)
p2 = Point(1, 1)
set([p1, p2])

Maybe it is silly, but I want to load the content of this file into python interactive shell, ie IPython . I thought I could just insert the line

from IPython.terminal import interactiveshell
interactiveshell

at the end of the file, but it didn't work. I thought I could use ipython name_of_the_file.py , but it didn't work either. I would like to instantiate maybe p3 without redefine the class in the interactive shell.

Question : How could I load the file and display the IPython interactive shell?

UPDATE

An interesting to know is the %load we could use to load the file into the IPython interactive shell.

Answer 1

From the command line you could do $ ipython -c yourfile.py -i , where -c is execute given file, and -i is "do not exit, start the repl" (which is the default unless -c is given.

Alternatively if ipython is already started you can use In[1]: %run -i myfile.py to run an already existing file in IPython. It is not exactly the same as IPython -c file -i , and if you came across weird effect look at the options of %run with In[1]: %run? .

Have also a look at %autoreload as well that might be able to watch your file for changes without restarting the IPython shell.
