What are some cool Python tricks?

1. >>> a =  "codementor" 
2. >>> print "Reverse is", a::-1 
3. Reverse is rotnemedoc  

1. >>> mat = [1, 2, 3, 4, 5, 6] 
2. >>> zip(*mat)(1, 4), (2, 5), (3, 6) 

1. >>> a = 1, 2, 3 
2. >>> x, y, z = a  
3. >>> x 
4. 1 
5. >>> y 
6. 2 
7. >>> z 
8. 3  

1. >>> print " ".join(a) 
2. Code mentor Python Developer  

1. >>> for x, y in zip(list1, list2): 
2. ...    print x, y 
3. ap 
4. bq 
5. cr 
6. ds  

1. >>> a = 7 
2. >>> b = 5 
3. >>> b, a = a, b 
4. >>> a 
5. 5 
6. >>> b 
7. 7  

1. >>> print "code"*4+' '+"mentor"*5codecodecodecode mentormentormentormentormentor  

1. >>> import itertools  
2. >>> list(itertools.chain.from_iterable(a))1, 2, 3, 4, 5, 6
