Drawing values from normal distribution to be used in Monte Carlo Simulation

I have defined a function, where the output is produced by a Monte Carlo Simulation.
When I make the call y(p,m,n,d), the output always stays the same "n" --> y = n



What am I doing wrong?



k = [0, 100]

for i in k:
p = np.random.normal(40,3,i)
m = np.random.normal(35,1,i)
n = np.random.normal(50,4,i)
d = np.random.normal(27,2.5,i)


def fct(p,m,n,d):
global u1
global u2
if np.any( n > 0):
return n
u1, u2 = np.asarray[np.log(0.6*n)], np.asarray[(math.e**d)**0.5]
if np.any(u1 != 0):
return u1
if np.any(u2 != 0):
return u2
if np.any( p > 0):
return p
G = np.log(p**2) + np.asarray(6*[math.e**(-m)]/u1) + 3/u2
return G

y = fct(p,m,n,d)

          You are always hitting this case:



           if np.any( n > 0):
          return n


          This is happening because of the way you define n:



          n = np.random.normal(50,4,i)


          The mean is at 50 and the standard deviation is 4. So, you have a range between 46 and 54 which will contain only positive values.

            You are always hitting this case:



             if np.any( n > 0):
            return n


            This is happening because of the way you define n:



            n = np.random.normal(50,4,i)


            The mean is at 50 and the standard deviation is 4. So, you have a range between 46 and 54 which will contain only positive values.
