In this hands-on lab, we will use Python loops to format our output by attempting to draw a geometric shape composed of asterisks.
Successfully complete this lab by achieving the following learning objectives:
- Create an Executable File with the Python Interpreter Path Instruction at the Beginning
Create a file called
Make it executable:
chmod +x asciiShape.py
Insert the instruction for the Python interpreter path:
- Write Two `for` Loops, with One Nested in the Other, to Draw a Pyramid
length = 10 astr = "*" for i in range(length): for j in range(length-i): print(" ", end='') print(astr) astr += "**"
- Write a Loop to Draw an Upside-Down Pyramid of Proportional Size that Aligns with the First Pyramid
length -= 1 space = 1 astrNum = ((length*2)-1) astr = "*" * astrNum for i in range(length): print(" " + space * " " + astr) astrNum -= 2 astr = "*" * astrNum space += 1
- Test It by Saving and Executing the File
Save and exit by pressing Escape,
:wq, and Enter.
Execute the file:
