derive an alogorithm using python for:

Psc = pseudo - critical pressure

Gp = cummulative gas production , scf

R = real gas constant

Tsc = pseudo- critical temperature

pi = initial reservoir pressure , psi

V = original gas volume, ft^3

zi = gas deviation factor at initial pressure

T = temperature, R

We = cummulative water influx , ft^3

Wp = cummulative water production , ft^3

RTscsscGp=2iRTpiV2RTp[y(WeWp)]
