python stata交互

python:
from sfi import Scalar
def calcsum(sum1, sum2):
    res = sum1 + sum2
    Scalar.setValue("result", res) #存入 scalar
a=1
b=2
calcsum(a, b)
end
//python函数建立一次，只要不关闭STATA则可一直使用
display result
python
calcsum(4,5)
end
disp result

//stata调用python .py文件
local a=1
local b=2
python script c:\python37\statax.py
disp result
python script c:\python37\statax1.py,args(`a',`b')
disp result
sysuse auto
python
from sfi import Data
