Here's a better example than the one Peter gave:

    if i>0: return sqrt(i)
    elif i==0: return 0
    else: return 1j * sqrt(-i)

versus

    if i>0:
        return sqrt(i)
    elif i==0:
        return 0
    else:
        return 1j * sqrt(-i)

To rephrase the dictum another way, "Don't try to stick too much code on
one line."
