CMG格式的离散裂缝数据，可以通过python语句自动生成，python语句格式如何设置？

以水力压裂生成的离散裂缝为例，指定射孔坐标位置，裂缝半长，缝高，渗透率等参数，通过python语句运算，自动生成文件，python语句如下：
File1 = open(“fraclocation.txt”,”r”)    **打开文件
list = []                                                 **列表
for line in File1:                                   **for循环 文件      
  stripped_line = line.strip()
  line_list = stripped_line.split()
  list.append(line_list)                        **列表填空
File1.close()                                          **关文件
XF = float(input(“Fracture Half-Length: “))                                       ** 半长，小数      
HeightUp = float(input(“Fracture Heigth Above Perforation: “))     **裂缝高度
HeightDown = float(input(“Fracture Heigth Below Perforation: “))   **裂缝高度
Perm = float(input(“Fracture Perm: “))                                              **裂缝渗透率
Width = float(input(“Fracture Width: “))                                                **裂缝开度
I=1                                                                                        **步长
with open(‘DFN.txt’, ‘w’) as f:                                                     **开启文件
 for line in list:                                                                     **循环列表
        print(“BEGIN_DFN ‘dfn”+str(i)+”‘”, “CMG 1”, file = f)       **打印 DFN表头
        print(“PERM-DF ALL” , Perm, file = f)                              **打印  DFN裂缝渗透率
        print(“APER-DF ALL”, Width, file = f)                                **打印   DFN裂缝开度
        print(“VERTEX”, file = f)                                             **打印  DFN裂缝坐标
 print(float(line[0]), float(line[1]) + XF, float(line[2]) – HeightDown, file = f)  **打印第一行坐标格式
print(float(line[0]), float(line[1]) + XF, float(line[2]) + HeightUp, file = f)   **打印第二行坐标格式
 print(float(line[0]), float(line[1]) – XF, float(line[2]) + HeightUp, file = f)   **打印第三行坐标格式
print(float(line[0]), float(line[1]) – XF, float(line[2]) – HeightDown, file = f)   **打印第四行坐标格式
 print(“END_DFN”,file=f)                                                       **打印结束语句
        i=i+1                      **循环步
f.close()        ** 结束
