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[0]
y = abc[1]
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
