+# all assignment 1 really needs to do is
+# read inputs from the console
+# do a calculation with those inputs
+# then print out the result
+
+# here is another example program that does something similar to this for ideas:
+
+# this is our main function
+# it is an example of how we define a new verb
+# like when we were using things like right() and left() in our drawing with
+# the turtle
+def main():
+    # every line that we want to be inside this function is going to be indented
+    # indentation is how the python interpreter, the thing that actually runs the code
+    # knows what to include in the function and what not to include
+
+    # let's use the input function to grab data from the command line
+    numEggs = float(input("Enter how many eggs you eat for breakfast every day: "))
+    eggsInAWeek = numEggs*7
+    dozensOfEggs = math.ceil(eggsInAWeek/12) # I just looked up the easiest function to round up to the nearest whole number
+    print(f"You're going to need to buy this many dozens of eggs: {dozensOfEggs}")
+
+#here we're outside the definition of main() again
+#and we're able to thus *call* main
+
+main()
+
+# and we can run this just by calling python3 exampleAssignment1.py on the command line (the shell in replit)
+
+
+# oh, btw, so that import math line up above?
+# it's there so we can use these other functions that exist in Python
+# in the "standard libraries"
+# what's a library? well basically it's code that was pre-written by other people that you can use
+# Python has A Lot of pre-written code in it
+# We'll see lots of examples of including libraries as we go along with the class
