如果某个键需要值，如何遍历字典列表并打印dict

Question

正如您在下面看到的，变量y包含一个字典列表，其中包含一些人的各种详细信息， 我想打印包含名为position='Account Manager'的关键字的字典

附言：我对Python还很陌生

y = [{'email': 'hgibson@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Hannah', 'lastName': 'Gibson', 'position': 'Corporate Flight Attendant'},

 {'email': 'ncucalon@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Nicole', 'lastName': 'Cucalon', 'position': 'Account Manager'},

 {'email': 'shazamy@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Sam', 'lastName': 'Hazamy', 'position': 'Maintenance Controller and Invoicing Specialist'}, 

{'email': 'rafaelbajares@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Rafael', 'lastName': 'Bajares', 'position': 'Gulfstream IV Pilot'}]

for i in y:
    if i.keys.position = 'Account Manager'
    print(i)

输出：

if i.keys() ='Account Manager':
            ^ SyntaxError: invalid syntax

您的解决方案似乎依赖于使用转换为点格式的字典（如Robot framework中的DotDict）。 通常，dctionary是这样读的y['position']

无论如何，此代码应该适用于您的要求：

y = [{'email': 'hgibson@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Hannah', 'lastName': 'Gibson', 'position': 'Corporate Flight Attendant'},
     {'email': 'ncucalon@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Nicole', 'lastName': 'Cucalon', 'position': 'Account Manager'},
     {'email': 'shazamy@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Sam', 'lastName': 'Hazamy', 'position': 'Maintenance Controller and Invoicing Specialist'},
     {'email': 'rafaelbajares@journeyflight.com', 'type': 'prospect', 'status': 'verified', 'firstName': 'Rafael', 'lastName': 'Bajares', 'position': 'Gulfstream IV Pilot'}]

for person_dict in y:
    if person_dict.get("position", "") == "Account Manager"
        print person_dict
