I go to University of Illinois at Chicago and takes a CS class with Dr. Sloan and he doesnt go over any of the specifics. He just babbles about how far computers have come in lecture, etc. I guess I'm going to take your online course as a supplement to get some meat in my CS diet. Thank you for this!

I assigned the variables inside the function to become A, B, and C, just in order to tell them apart from the global variables. I find it easier for beginners to learn what is happening this way, without mixing up what is happening. My code looks like this:


x = 1
y = 2
z = 3

def f(A=0, B=0, C=0):
out = A**2 + B**2 + C**2
return out

print "f1 = ", f(x, y, z)

print "f2 = ", f(x, y)

print "f3 = ", f(B=y, C=z)

print "f4 = ", f(B=x, C=y)

print "f5 = ", f(0, 1, 2)


And this would return:
f1 = 14
f2 = 5
f3 = 13
f4 = 5
f5 = 5

Just thought that this might be helpful.

how can I make the output (Y) appears in the variable explores?

[thewildernessoutdoorboys]

when using conditionals in my spyder I type "

age=21

if age < 16:
print(" You cant drive ")
if age > 16
print(" you can drive ")

But a TypeError that says " '<' is not valid between str. int.
What is wrong?
THANKS Dr. Easton
