Just as an additional example, let's assume I'd want to add the area of
to circles.
The source-file would look something like this:
------>snip source.py snip<------
#! /usr/bin/python3
from math import pi as PI
code1="""
d1= 3.0
A1= d1**2 * PI / 4.0
"""
exec(code1)
print(code1)
print("Area of Circle 1:\t", A1)
code2="""
d2= 5.0
A2= d2**2 * PI / 4.0
"""
exec(code2)
print(code2)
print("Area of Circle 2:\t", A2)
Sum_Of_Areas= A1 + A2
print("Sum of areas:\t", Sum_Of_Areas)
------->snip<------------------
And the output is:
d1= 3.0
A1= d1**2 * PI / 4.0
Area of Circle 1: 7.06858347058
d2= 5.0
A2= d1**2 * PI / 4.0
Area of Circle 2: 19.6349540849
Sum of areas: 26.7035375555
which can be explained to anyone who knows
basic math and is not at all interested in
python.
