python - What does In [*] in IPython Notebook mean and how to turn it off?

Question

I use Windows 7, Python 2.7.9 plus latest version of IPython 3.1.

I ran %python inside an IPython Notebook and ran the cell, instead of returning the Python version, it did not run and jumped to a new line and printed a In [*] instead of a line number. Now no line is running in ipython everything is ignored when I try to run a cell value.

Anyone know what has happen?

Answer 1

The kernel is busy. Go to the menu Kernel and click Interrupt. If this does not work click Restart. You need to go in a new cell and press Shift + Enter to see if it worked.
