Hello,

I encountered the following problem. When I a write a file test.sage with one line:

print a

in the terminal I define a function,

def test2():
   a=1
   load("test.sage")

When I run test2() in the terminal, I get the error message

NameError: name 'a' is not defined

My question is, how do I specify the value of a in test.sage when I load it?

Thanks in advance!

You can declare a as a global variable:

def test2():
    global a
    a=1
    load("test.sage")

Remember that SageMath now is based on Python 3, so you should write print(a) if you use SageMath 9.0.

thank you <3
