use package with import
Now we can import the module from the package and use that.
import sys
import os
sys.path.insert(0, os.path.join(
os.path.dirname(os.path.dirname(os.path.abspath(__file__))),
'2' ) )
import mymath
print(mymath.calc.add(4, 7)) # 11
from mymath import calc
print(calc.add(5, 9)) # 14
