Grids Are Everywhere! 🟦
Hi builder! 👷 A grid is rows and columns, like a chessboard, graph paper, or a tile floor! 🟦🟦🟦
Today we use nested loops to draw our own grids. Let's go!
for row in range(3):
print('A new row!')Rows and Columns 📏
A grid has two parts:
- Rows go side to side ↔️
- Columns go up and down ↕️
The outer loop makes rows, the inner loop fills the columns!
for row in range(2):
for col in range(4):
print('o', end='')
print()The end='' Trick 🤫
Normally print jumps to a new line. To keep things on the SAME line, we add end=''. 🤫
Then we use an empty print() to jump down to the next row!
print('a', end='')
print('b', end='')
print('c')A Tiny 2x2 Grid 🔲
Let's draw a grid with 2 rows and 2 columns. That's 4 little squares! 🔲🔲
for row in range(2):
for col in range(2):
print('#', end='')
print()Add Some Spaces 🌬️
If we put a space after each symbol, the grid looks neater and wider! 🌬️
Try print('#', end=' ') with a space inside the quotes.
for row in range(3):
for col in range(3):
print('#', end=' ')
print()A Big Wide Grid 🟩
Want a bigger grid? Just change the numbers in range()! More rows go down, more columns go across. 🟩🟩🟩🟩
for row in range(4):
for col in range(8):
print('@', end='')
print()Grid With Emojis! 😎
Who says grids have to be boring? Let's fill ours with emojis! 😎 Try frogs, stars, or hearts!
for row in range(3):
for col in range(5):
print('🐸', end='')
print()Numbered Grid 🔢
We can show the column number in each spot! This helps us SEE how the inner loop counts. 🔢
for row in range(2):
for col in range(4):
print(col, end=' ')
print()Checkerboard Idea ♟️
Real checkerboards switch colors! We can switch symbols too. For now, let's just keep one symbol — but imagine the possibilities! ♟️
for row in range(4):
for col in range(4):
print('■', end=' ')
print()Make It a Square 🟧
If rows and columns are the SAME number, you get a perfect square! Try 5 and 5. 🟧
size = 5
for row in range(size):
for col in range(size):
print('*', end='')
print()You Are a Grid Master! 🏆
Change size to any number and watch your square grow or shrink! 🏆
Try size 3, then size 7. Cool, right? Playing with numbers is the best! 🎮
size = 3
for row in range(size):
for col in range(size):
print('❤️', end='')
print()Quick Check! 🧠
Let's test your grid powers! 💪
Grid Champion! 🎉
Amazing work! 🎉 You can draw grids now!
- Outer loop = rows (down) ↕️
- Inner loop = columns (across) ↔️
end=''keeps stuff on one line 🤫- Empty
print()jumps to a new row ⬇️
Next: triangles made of stars! ⭐
for row in range(3):
for col in range(6):
print('🟦', end='')
print()
