问题 I've been trying to get a fix and can't find why the error keeps appearing. Pmin,Pmax,w,fi1 and fi2 have all been assigned finite values guess=Pmin+(Pmax-Pmin)*((1-w**2)*fi1+(w**2)*fi2) When i remove this line from the code, the same error appears at the next line of code, again for no reason I can think of Edit: Here is the chunk of code I was referring to: def Psat(self, T): pop= self.getPborder(T) boolean=int(pop[0]) P1=pop[1] P2=pop[2] if boolean: Pmin = float(min([P1, P2])) Pmax = float

问题 I am working on a project that creates a simple perimeter and area calculator based on the values the user inputs. (For finding window perimeter and glass area).

问题 Hello Stack Overflow Community, I am trying to write a program that checks Fermat's Last Theorem. The issue I am running into is that an error appears saying "NameError: name 'a' is not defined.
