I'm moving on to chapter 9

fucking frustrating and doesn't seem to work for the time being and I have a very
bad temper).
At least for chapter 9, I got the first part correct at first try --- define a
function that takes and prints the smallest of 3 numbers. I pasted it here for
reference and discussion. The code can also be further modified to include a
clause that says that if two numbers tie for smallest, choose any of the two
numbers. (I will attempt to do it and then post it here again for future
discussion with users here
def min3(a, b, c):
min3 = a
if b < min3:
min3 = b
if c < min3:
min3 = c
if b < c:
min3 = b
return min3
print(min3(4, 7, 5))
4
The exercise says you must use an if/elif chain. The first thing that
comes to mind is:
def min3(a,b,c):
if a<=b and a<=c:
return a
elif b<=a and b<=c:
return b
else:
return c
The bit about numbers tying for smallest is not meaningful; the caller
can't tell if a minimum value of 42 came from a, b or c.
