How to move a large section of Python code forward by one tab under vim?

Question

I pasted a large section of python code under vim, but starting from a certain line, all the code was moved back by one more tab. There were more than 100 lines. I manually adjusted them one by one, and I was exhausted.

Is there any way to make it easier?
