Unexpected behavior of Enter inside a code block. #314

Closed gepcel closed 6 years ago

gepcel commented 6 years ago

I don't know how to name this issue, trying to describe it by an example. If I want to input a code like the following:

for i in range(3):
    a = i + 1
    print(a)

The code would be stopped and executed immediately when hit Enter after a = i + 1. It used to be like needing to hit Enter twice after print(a).

I'm using Windows 10, and the packages I'm using:

A similar bug was detected in the IPython terminal. It seems to be fixed there. See 11358.

Thanks for reporting. I'm preparing a new release (4.4.3) to fix this.
