- M-w copy region
- C-y paste
Range
- Loops can make repetitious code easier to write
- Example of drawing a triangle
- Codes is easier to read and easier to write because it has fewer opportunities for errors
- Writing
for i in [0, 1, 2]: is annoying for large numbers
- Use the range function instead
for i in range(3): will run three times- Update the triangle drawing
- The iterator variable, i, will start at 0 and end at n - 1
- What if we wanted to print 1, 2, 3 with the range function?
