Errors with sage_eval
I try to use function
sage_eval and It seems for me that either I found bug either I don't understand smth.
cmds = """ def somef(): return 443 res = somef()""" sage_eval('res', cmds = cmds)
NameError: global name '_sage_const_443' is not defined
sage_eval('res', cmds="def somef(): return 443; res=somef()")
NameError: name 'res' is not defined.
Please give me some hints how to solve this problem. Thanks in advance.
Best regards, Andrei.
