# Python Coding challenge - Day 153 | What is the output of the following Python Code?

### Code:

def some_func(a, b, c=0, d=1):

return a + b + c + d

result = some_func(1, 2, d=4)

print(result)

### Solution and Explanation:

This code defines a function named some_func which takes four parameters: a, b, c, and d. Parameters c and d have default values of 0 and 1 respectively. The function calculates the sum of all four parameters and returns the result.

Here's the breakdown of the function:

a, b, c, and d are parameters representing values that can be passed into the function.

c=0 and d=1 in the function signature are default parameter values. This means if you call the function without providing values for c and d, they will default to 0 and 1 respectively.

Inside the function, it calculates the sum of a, b, c, and d and returns the result.

Now, when the function is called with some_func(1, 2, d=4), the values passed are a=1, b=2, c is not specified (so it takes the default value of 0), and d=4. Therefore, the function computes 1 + 2 + 0 + 4, which equals 7.

Finally, the result, which is 7, is printed using print(result).
