swapping in python

1a = 10
2b = 20
3print("not swiped value of a is",a)
4print("not swiped value of b is",b)
5stored_value = a
6a = b
7b = stored_value
8print("swiped value of a is",a)
9print("swiped value of b is",b)

1a = 5
2b = 6
3# now swp the variables
4a, b = b, a
5# to swap two variables you need an other string harder than the first one
6c = a	# 5
7a = b	# 6
8b = c	# 5

3    tmp = s1[:]
4    s1[:] = s2
5    s2[:] = tmp

7# However, the easier and better way to do a swap in Python is simply:
8s1, s2 = s2, s1
