如何从 python 字典中的元组访问密钥

Question

>我有这样的字典;

  csvDict[key] = {'delivery': delivery, 'tanksystemid': tanksystemid}

我试图做这样的状况检查;

tanksystemid=100
for dic in csvDict.values():
                if tanksystemid == dic['tanksystemid']:
                    key of csvDict?

如何获取csvDict的密钥？

Answer 1

您只需使用 csvDict.items() 而不是 csvDict.values() 。喜欢 (python3( ：

tanksystemid=100
for key, dic in csvDict.items():
                if tanksystemid == dic['tanksystemid']:
                    # key of csvDict?
                    print(f'key: {key}')
