ArcPy中：字典语法错误“无法分配到函数调用”

Question

我试图找到“CrudeRate”及其相关的“STATE_NAME”使用下面的代码的最大值：

import arcpy 
arcpy.env.workspace = "C:\\" 

shp = r"C:\\USCancer2000.dbf" 
rows = arcpy.SearchCursor(shp) 
CrudeRate= "CrudeRate" 
State_name= "State_name" 

out_dict = {} 
for row in rows: 
    for C in CrudeRate: 
     lst = [] 
     if row.CrudeRate == C: 
      lst.append(row.CrudeRate) 
     out_dict(C) = max(lst) 
del row,rows 
for CrudeRate in out_dict: 
    print CrudeRate, State_name 

但是当我运行它，我得到：

Sytnax error: Can't assign function call

有谁看到的问题以及如何解决它？

Answer 1

分配字典值时，您需要使用括号代替parentesis。

out_dict[C] = max(lst)
