## Python: Tips of the Day

Decompose a collection:

Assume we have a function that returns a tuple of two values and we want to assign each value to a separate variable. One way is to use indexing as below:

```abc = (5, 10)
x = abc
y = abc
print(x, y)
```

Output:

```5 10
```

There is a better option that allows us to do the same operation in one line.

```x, y = abc
print(x, y)

```

Output:

```5 10
```

It can be extended to a tuple with more than 2 values or some other data structures such as lists or sets.

```x, y, z = {1, 2, 3}
print(x, y, z)
x, y, z = ['a', 'b', 'c']
print(x, y, z)
```

Output:

```1 2 3
a b c
```
