Python Brain Teasers

## Let's try it!
Try executing the code below to verify the result: 

avengers = ['Bruce', 'Carol', 'Natasha', 'Tony']
idx = 3
avengers[idx], idx = 'Peter', 2  
print(avengers)

## Explanation
In this exercise, we’re doing multiple assignments, which is also known as **unpacking**.

In **line 3**, Python will first evaluate the right side of the `=` from left to right. It will then evaluate the left side, again from left to right.

In the line `avengers[idx], idx = 'Peter', 2, Python first evaluates avengers[idx] = 'Peter’`. Since `idx` is still third here, the fourth item on the list, `Tony`, is being replaced. Then Python will evaluate `idx = 2`.

Multiple assignments can be confusing and considered bad practice, so try to avoid this practice.
