2. Yesterday’s Lab Activity A
New ways to print on the same line
What gave you the most trouble in Activity B?
How did you address this?
What gave you the most trouble in Activity C?

3. New ways to print # Playing with print endings x = 0 while x<10:
print(x, end=‘ ’)
x=x+1
print()
print(“Final value of x is”,x)

4. What code could we write to print a triangle?
* * * * * * * * * * * * * * *

5. What code could we write to print a triangle?
First we need to figure out how to print one line of stars of varied length
Next, we need to do this over and over

6. Important things Name your variables descriptive names!
x, y, z, a, b, c don’t make much sense with nested loops
Once you figure out what you need to do, write a detailed comment about it
Start by solving a small problem, then work up to larger problems
If all else fails, step through the program line by line

7. What about a right-justified triangle?
* * * * * * * * * * * * * * *

8. What about a right-justified triangle?
We need to print spaces before the stars
To solve the problem, we need to think about 2 things
Number of spaces
Number of stars
