question. The book I'm working through hasn't covered using flow control
yet so I'm thinking there should be a way to do this without the for
loop I used, but I'm at a loss here.
Thee are ways to do it without using a for loop but they are
all more advanced rather than simpler. (And they are less
"good" than the simple program you have written in that they
are unnecessarily complicated)
So far the book has covered: lists,
strings, numerical types (float, integer, etc), methods, tuples,
importing modules, boolean logic, and mathematical operators.
You used a list comprehension in your solution, was that
covered as part of lists? If not how did you find it?
nums = input('Enter some numbers separated by commas: ')
nums = [float(i) for i in nums.split(', ')]
print((sum(nums)) / len(nums))
That's about as simple as it gets except for the surplus
of parens in the last line:
print(sum(nums) / len(nums))
is sufficient.
I had done a little bash, C, and Visual Basic so I figured a for
loop would be a good way to do this (that's how I came to the idea of
using 'for' anyway). This is my first effort since college to try and
really learn some programming, was a hodge podge networking program and
I didn't realise how useful or in demand some programming would be. If I
remember correctly I was looking for how to do a for loop in python3 but
I don't remember the terms I threw into DuckDuckGo (it definitely wasn't
list comprehension). I believe I bookmarked it though. I ended up at a
Stack Overflow page with instructions on how to do this.
I'll have to skim through the chapter and see if I can find list
comprehension, if not I'll check the back of the book for where it's
mentioned. Wolfgang was on the money when suggesting the book was python2.

Bryon
