Removing/Replacing Prints in Python 3

Question

So I'm working on a basic program and I'm trying to make two things:

1. A Loading... text line where the dots increase in this manner:

   Loading.

   Loading..

   Loading...

   Loading.

   Loading..

   Loading...

2. An increasing percent in one line:

   1% Complete...

   3% Complete...

   etc.

So, my question is how do I remove/replace printed text? I want these things to happen on one line. For the first example, how do I replace the 3 dots with just 1, or just erase the 2 on the end (without going to the next line)? For the second example, how do I make the percent increase while staying on the same line?

Answer 1

>>> for i in range(100):
...    time.sleep(1)
...    sys.stdout.write("\r%d%%" %i)    # or print >> sys.stdout, "\r%d%%" %i,
...    sys.stdout.flush()
... 

This will help you with the percentage.
