IPython - cycle through blocks in input history?

问题

Say I input the following:

def foo():
    print(2)

Then later, when I want to edit my function, I press the Up arrow key to rewrite it, and that cycles through my inputs one line at a time (i.e. first it shows print(2), then def foo():). Is there any way to make it cycle through blocks of code the way IDLE does it?

回答1:

I have this problem with an earlier version of iPython on Linux (11 I think). New versions do not do this.

I currently still use 11, and my solution was to just use the iPython qtconsole instead which does what you want. I would assume it would do the same on Windows.

回答2:

Since IPython has stopped using readline, this issue has come back, the "solution" is to use PageUp and PageDown instead C-up and C-down.
