Minimal VII: Lambda Functions

Check the principles of minimalist code in the [intro to the first challenge] (https://innokodakademija.com/challenge/2XLjgZhmACph76Pkr).

In the Code tab you will find a code that is missing a single character in order to pass the tests. However, your goal is to submit a function as minimalist as possible. Use the tips in the tips section below.

Write five adder functions:

• add_2(x) should return 2 + x.
• add_3(x) should return 3 + x.
• add_5(x) should return 5 + x.
• add_7(x) should return 7 + x.
• add_11(x) should return 11 + x.

Tips

Functions that consist only of a return can be written as a one-liner with a lambda function.

For example, the code:

def are_same(a, b):
    return a == b

Can be simplified to:

are_same = lambda a, b: a == b

Bonus

lambda a, b: a == b is technically an anonymous function. However, it can be assigned to the identifier are_same and it can then be called using are_same().
