If x is a C variable of type PyObject*, and I happen to know already that
the object is of a numeric type, say int, is there a way to change the
value of x in place to a different number? In the C/API documentation I
found routines to increment or decrement it in place, but I didn't find a
routine to simply replace its value by a different value. (I suppose I
could change it to the new value via an increment or decrement, but this
is ugly as well as being susceptible to overflow problems and roundoff
errors in the case of floats.)

If you do figurte out how to do what you want, you will put us in the
old FORTRAN trap: People can write code that changes the value of a
constant.
The code:
month = 12 # make it december
inches_per_foot = 12
make_previous(month)
print ('Month is now: %s, inches_per_foot = %s' % (
month, inches_per_foot))
might print:
Month is now: 11, inches_per_foot = 11
