I would like to rapidly report stored values along with the variable name. In python I can do print('A=' + A) for this, which does not seem to work in Sage. Is there a command with this function or a way to fix this print statement?

You can? This doesn't work in Python 2.6, anyway, and yields the expected error. Is it possible that this works in Python 3?

The initial `var` was erroneous, because the `A=10` cancels that out.

print('A=' + A) doesn't work for me in Python 2.6 or 3.2 (unless A happens to be a string). What does work in Python, and in Sage, is print('A=' + str(A)). You have to convert the variable to a string before you can concatenate it with another string.

Some options:

sage: print 'A=',A
A= 10
sage: print 'A='+`A`
sage: print 'A=%03d'%A
