Hi there,

I currently encountered a problem: I want to handle adding strings to other strings very efficiently, so I looked up many methods and techniques, and I figured the "fastest" method. But I quite can not understand how it actually works:

def method6():
    return ''.join([`num` for num in xrange(loop_count)])

From source (Method 6)

Especially the ([numfor num in xrange(loop_count)]) confused me totally.
