POTD 1: How’d it go?
- Don’t submit the test file (P01_quiz1_test.py)
- Make sure the program you submit has the correct filename (P01_quiz1.py)
Monday lab: how was it?

After you’ve submitted the exercises as a team, do one or more of the following:

Compare your solutions to POTD 1. Are they identical? Similar? Completely different?
As a team, try to solve the problem listed under Other Practice Problems in the POTD 2 prompt:
Suppose that you are writing a program and you have two variables x and y that contain values. You’d like to swap the values stored in those variables, so what was previously stored in x is now stored in y and what was stored in y is now in x. For example if the following program is completed with your code, it should output 4 10. Note: your solution should not depend on the specific values (e.g., 4 and 10) - it should work regardless of what x and y are set to.
```
x = 10
y = 4
# your code here
print(x, y)
```
Discuss and begin working on POTD 2

Example program: print the sum of 3 user-supplied numbers

Notice that this program uses both command line arguments and an input prompt.
