When you run code in Python, there’s a lot happening under the hood. This course sheds light on some of the interesting parts of Python you might be unaware of. 

As you progress through it, you’ll learn some tools and tricks that every Python programmer should know to avoid common mistakes. You can think of the course as a “Python hacks” handbook. 

Python basics are a prerequisite, but this is a beginner-level course. Each lesson is independent and after the first chapter, you can pick up from any lesson and you’ll be able to follow along comfortably.

Python FTW: Under the Hood

Let's see the solution to the previous challenge.

<h2> Solution </h2>


def generate_grid(n_rows, n_cols):
  row = [0] * n_cols
  grid = [row[:] for _ in range(n_rows)]
  # 2 more possible ways of doing the same.
  # grid = [row.copy() for _ in range(n_rows)]
  # grid = [[0] * n_cols for _ in range(n_rows)]
  return grid

def assign(grid, row, col, value):
  grid[row][col] = value
  return grid

rows, cols = 9, 9
sudoku = generate_grid(rows, cols)
print(assign(sudoku, 1, 0, 9))

<h2> Explanation </h2>

- The solution is related to the “tic-tac-toe” lesson. All we need to do is make sure that all the rows are different objects in the memory.
- `[:]` is a Pythonic way of copying a list into a new variable.
- The `copy` method was added in Python 3.3 to achieve the same effect.
