Conditional Steps - if ... elif .. else
if (expression): (command) elif (expression): (command) else: (command)
Conditional Steps (Multi elif) - if ... elif .. else
if x < 0: x = 0 print 'negative changed to zero' elif x == 0: print 'zero' elif x == 1: print 'single' elif x == 2: print 'double' else: print 'more'
Repeated steps - while
while i < 6: print "At the top i is %d" % i
Loop - for
for (y) in (x): (command)
