result = square(4)
print(result) # This would output: 16
please explain
The given code snippet calls the function `square()` with an argument of `4` and assigns the returned result to the variable `result`.
The `square()` function takes a number as input, squares it (multiplies it by itself), and returns the squared result.
In this case, when `square(4)` is called, the function squares `4` and returns `16`. So, the value `16` is assigned to the variable `result`.
Finally, the `print()` function is used to display the value of `result`. Thus, the output of the code will be `16`.
