Break for While and For

[juniorcoder]

Not tested but something like

while True: random.randint() #I compute something else here ,but accordingly I might generate new random values if any(self.Itm[k][l]<0 for k in range(self.p.T) for l in range (self.p.N)): print("negative quantity, generate random periods again") else: break

There might be better solution but without seeing rest of the code is difficult to say (i.e. I don't like this double for in the comprehension expression)

Thank you Buran , it worked !!!
