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?
