And I cannot get this program to work. Any ideas?

sin60=0.866025
w=input('width?')
a = w / 2
b = a / sin60
c = b / 2
r = ( b / 2 ) + c
r

 

Try:

w=float(input('width?'))

I think that 'input' returns a string.

 

OK, thanks, will do.

 

I thought about learning Python. That was before I decided I could get by with Perl, shell scripting, and C.

 

Didn't work not sure why.

 

Tried something else that did not work.

 

And again:

 

Sin60 and sin60 are two different names -- watch the upper lowercase...

 

Change line 7 to...
print(r)

 

Thanks that did it.

 

Also change input line to...

print("Enter Width:")
w=float(input())

If you are using an online simulator of Python, you cannot use the input command.

 

Actually I can and did, I also used input to freeze the display so I can view the result.

sin60 = float(0.866025)
w = float(input('width?'))
a = w / 2
b = a / sin60
c = b / 2
r = ( b / 2 ) + c
print(r/2)
z=input()

 

The weird part is I wrote the code using notepad then changed the ext to .PY after saving it. Clunky but I am learning. Hey, it was my first real program in Python. Now on to loops.

It is much easier to use a Python IDE - like IDLE

it is much, much easier to learn with w3schools.com (or similar). It hasPython simulator built into the site.
https://www.w3schools.com/python/default.asp

 

If you have Python installed on a windows machine, you should be able to right click on a .py script and select "edit" - the Idle IDE should open. You can also look at your start menu to see if the windows IDE popped up in there when you installed Python. Last option, type "idle" in the start search box. All (any) should work.
The IDE us very easy to use and there is an IDLE shell that opens each time you click run to test your script.

 

Baby steps. I gave up on Idiots guide to Python. I used this site instead which I got from another member.

Another Python IDE that is intended for learners is Thonny.

That's the new default on raspberry pi

 

Try this way:

sin60=0.866025
print('Width?')
w= int(input())
a = w / 2
b = a / sin60
c = b / 2
r = ( b / 2 ) + c
print(r)

sin60=0.866025
print('Width?')
w= int(input())
a = w / 2
b = a / sin60
c = b / 2
r = ( b / 2 ) + c
print(r)

Why should the width of a nut be required to be an integer?
