I have seen this '[A' in a progress bar module but I can’t figure out what it does.
As in:
print '[]', chr(27) + '[A'
Do you know what it does??

It’s a VT100 Escape sequence; it moves the cursor up.
Note that the
chr(27)initiates the sequence. Often, this might be written"\033[A"(since33oct == 27dec). If you’ve ever added color to a bash prompt, you’ve seen this.
