I actually needed to read those twice to get their meaning. I think
hash .= hexdigest()
num .= value
would have been clearer (yes, I nag my colleagues about white-space,
too).
Do you have any examples (preferably from real code) where you don't
assign to a simple variable? I feel that
x += 1
isn't much of an improvement over
x = x + 1
but
self.data[line+len(chars)-1] += after
is definitely an improvement over
self.data[line+len(chars)-1] + self.data[line+len(chars)-1] + after
