We could be a lot more helpful if you just spelled it out.  digits and 
getcontext() are not builtins, so we don't really know how you're using 
them, except by guessing.

You've changed the code, probably by using one of the many suggestions 
here.  But what's it look like now?

You should have started the thread by telling us the Python version. 
I'm guessing you're using python 3.x


In Python 3.x, input() returns a string.  So you can tell how much the 
user typed by doing a len() on that string.  Once you convert it into 
some other form, you're choosing the number of digits partly by how you 
convert it.

Can you state what your real assignment is?  And what code you have so 
far?  And just what is wrong with it, that you need to change?

For example, if the "correct" answer for your user is "7.3"  and the 
user types  "7.300" is that supposed to be right, or wrong?
