Using Zip to combine arrays You can zip the two arrays with:

b = [[1, 2, 3, 4], [6, 5, 4, 3]]
zip(*b)
[(1, 6), (2, 5), (3, 4), (4, 3)]

Reverse a list To reverse a list, you could implement a function. But why go through the trouble if it's already implemented?

b = [1,2,3,4,5]
b.reverse()
print b
[5, 4, 3, 2, 1]

Reverse a string Instead of creating a method to reverse a string you can use:

s = "Hello world"
s = s[::-1]
print s
dlrow olleH

Swapping variables You do not need to define a temporary variable to swap to variables in Python:

a = 1
b = 3
b,a = a,b
print a
print b
1
