Update: I downloaded the sagemath tar.gz file, unpacked it, went into its directory, and typed "make." It didn't take all day on my machine: maybe 15 minutes. Then I copied saga to python. If I entered python, I got plain old python2.7. If I entered ./python, sage loaded just as if I had entered ./sage, but only after a few bad starts with messages about SAGE_PATH. Now sage loads quickly every time with ./python in the sage directory.
PyCharm steadfastly refused to accept sage as an interpreter, but did allow sage disguised as "python." In PyCharm Tools / Run Python Console brought up the usual sage text. I loaded sage math modules and it seemed I I had random() divisors() covered but these functions were not recognized. On the sage command line, integer.divisors() yields all of the integer's divisors, which are only itself and 1 in the case of prime numbers. So, sage is my PyCharm interpreter but the sage modules of interest, which seemed to load successfully, are not working.
