如何修复我的jupyter笔记本/实验室

Question

When I code in jupyter notebook/lab, if I press enter, two new lines will be generated, like this:

If I press tab, the code hint appears, but the cursor jump to the next cell, like this:

These two problem appear recently, I have uninstalled all ipython & jupyter and reinstall, change browser from chrome to firefox, even when I code in google colaboratory and coursera's deeplearning exercise, except in pycharm.

Answer 1
