How to use Python Win IDE

[Phillip]

Is there a document teaching people how to use the IDE to do programmin?
Cause it is not like the other IDE for other programming language that I
used, eg VB, or Cbuilder, it's like that when I made a mistake, I cannot go
back to the line that contain the mistake and delete it, i had to undone
everything, maybe it's just me, but is they a better way? Thx for reading
