让我的 python 脚本工作并调用我的变量的问题

Question

我正在为管道类构建一个 python 脚本，并在主脚本中定义一些变量，并制作了一个可执行脚本，该脚本调用主脚本并为具有真假逻辑的区域赋予值以确定是否需要一个地区与否。我对 python 了解不多，并且确实会很感激这方面的任何帮助。我将包括我的脚本中与提到的问题相关的部分。

#this is the main program 

import numpy as np
import sys

uCounter = 0

class Pipe(object):
   global uCounter

   def __init__(self, nPorts, volume):
      self.volume = volume
      self.rhoj = D(1)
      self.Pj = D(1)
      self.nPorts = nPorts  
      self.freePorts = []
      self.portSetm = []  
      self.portSetP = []
      self.portSetValue = []  
      self.portSetAreas = []  
      self.portSetAreasValue = [] 
      for i in range(nPorts):
         self.freePorts.append(i)
         self.portSetm.append(False)
         self.portSetP.append(False)
         self.portSetValue.append(0.0)
         self.portSetAreas.append(False)
         self.portSetAreasValue.append(0.0)
      self.m = D(self.nPorts)
      self.P = D(self.nPorts)
      self.Areas = D(self.nPorts)
      self.pd = np.zeros((self.nPorts))
      self.dt = 0.0  

   def logics(self, freePorts):                                                                                  
      for port in range(nPorts):
         if self.portSetAreas[self.freePorts[port]] != 0:
            self.Areas[port] = self.portSetAreasValue[self.freePorts[port]]

   def Values1(self):
      equation = Equation(1, uCounter)
      for p in range(self.nPorts):
         equation.A[0, self.m.gid[p]] = self.Areas[port]
      equation.c[0] = 0.0
      return(equation)

#and this is the executable 

import math
import numpy as np
import sys
import scipy.io
import mainproject

Pipe1.portSetAreas[0] = True
Pipe1.portSetAreasValue[0] = 0.1
Pipe1.portSetAreas[1] = True
Pipe1.portSetAreasValue[1] = 0.1

#0 refers to the inlet of the pipe
#1 refers to the outlet of the pipe

equation.A[0,self.m.gid[p]] = self.Areas[port]
NameError: global name 'port' is not defined

Answer 1

您在 for 循环中定义 p 而不是 port。

     for p in range(self.nPorts):
         equation.A[0, self.m.gid[p]] = self.Areas[port]

也就是说，您的代码中还有其他逻辑错误。

这段代码也会导致错误：

   def logics(self, freePorts):                                                                                  
      for port in range(nPorts):

您可能应该将您的范围调用更改为range(self.nPorts)。
