我的CSV文件是
200
Service
我在解释器中输入的代码是
snav = csv.DictReader(open("screennavigation.csv"), delimiter=',')
print snav.fieldnames
['200']
for line in snav:
... print(line)
...
{'200': 'Service'}
snav["200"]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: DictReader instance has no attribute '__getitem__'
我以为DictReader是为了返回字典.我怀疑我错过了一些非常明显的东西.
最佳答案 snav对象是DictReader实例,不应该作为字典访问.在迭代时,它会生成可以相应访问的字典:你需要行[‘200’]
