Python Programming

Did you manage to complete the swapping exercise?

Now, you might have tried the following as the first attempt. And it does not work.

x and y are both 24 after swapping.

x = 15
y = 24
x = y
y = x
print(x)
print(y)

What happened here was that I have already updated x to point to 24 in Line 3, and there is no longer a way for you to access the reference to 15!

So, to be able to swap variables, you will need to introduce another variable to point to what x is pointing (15) first. Then you update x to point to what y is pointing to (24), then update y to point to what your temporary variable is pointing (15).

x = 15
y = 24
temp = x
x = y
y = temp
print(x)
print(y)
