swap function for array in python inbuilt code example
Example 1: swapping variables in python
a = 1
b = 2
a, b = b, a
# a = 2 , b = 1
Example 2: python swap function
def swap0(s1, s2):
assert type(s1) == list and type(s2) == list
tmp = s1[:]
s1[:] = s2
s2[:] = tmp
# However, the easier and better way to do a swap in Python is simply:
s1, s2 = s2, s1
