比较两个字典值并更新字典 [英] compare two dict values and update in dict

问题描述

我有疑问要比较两个字典之间的价值。我正在与 jarname jarverion进行比较。在两个字典上。如果相同，则需要将其更新为 true。在dict1部分（如果版本不同）中，我需要在dict1.Overwrite部分中设置false。

I have question to compare value between two dicts. I am comparing with "jarname""jarverion" on both dict. If its same , i need to update as "true" in dict1 section if its different version , i need to set false in dict1.Overwrite section.

dict2={'partname1': { 'jarversion':'1.0','jarname':'jar1.jar'},'partname2': { 'jarversion':'2.0','jarname':'jar2.jar'},'partname3': {'jarversion': '3.0','jarname':'jar3.jar'}}


dict1={1:{'partition_name' : 'avs', 'jar':[{'jarversion':'1.0','jarname':'jar1.jar'},{'jarversion':'5.0','jarname':'jar5.jar'}]},2:{'partition_name' : 'ivs', 'jar':[{'jarversion':'4.0','jarname':'jar4.jar'},{'jarversion':'2.0','jarname':'jar2.jar'}],}}

我比较dict1 jarverion jarname

I comparing dict1 "jarverion""jarname" with dict2 dict using below code.

res=[]
for _, v in dict2.items():
    res.append(v['jarname'] + v['jarversion'])


def cmp_value( rstring='',lstring=''):
    print('rstring',rstring)
    print('lstring',lstring)
    if rstring == lstring:
        return True
    else:
        return False
for key, val in dict1.items():
        print(val)
        for eachval in res:
            if cmp_value(eachval, "%s%s"%(val['jarname'], val['jarversion'])):
                dict1[key].update({"overwrite": "true"})
                break
            else:
                dict1[key].update({"overwrite": "false"})

print (dict1)

但是此代码不起作用，我正在获取

But this code is not working , i am getting

if cmp_value(eachval, "%s%s"%(val['jarname'], val['jarversion'])):
KeyError: 'jarname'

任何人都可以在这里帮助我。

Can anyone help me here.

推荐答案

dict2 = {'partname1': {'jarversion': '1.0', 'jarname': 'jar1.jar'},
         'partname2': {'jarversion': '2.0', 'jarname': 'jar2.jar'},
         'partname3': {'jarversion': '3.0', 'jarname': 'jar3.jar'}}

dict1 = {1: {'partition_name': 'avs',
             'jar': [{'jarversion': '1.0', 'jarname': 'jar1.jar'}, {'jarversion': '5.0', 'jarname': 'jar5.jar'}]},
         2: {'partition_name': 'ivs',
             'jar': [{'jarversion': '4.0', 'jarname': 'jar4.jar'}, {'jarversion': '2.0', 'jarname': 'jar2.jar'}], }}

res = []
for _, v in dict2.items():
    res.append(v['jarname'] + v['jarversion'])


def cmp_value(rstring='', lstring=''):
    # print('rstring', rstring)
    # print('lstring', lstring)
    if rstring == lstring:
        return True
    else:
        return False


for key, val in dict1.items():
    for eachval in res:
        for i in val['jar']:
            if cmp_value(eachval, "%s%s" % (i['jarname'], i['jarversion'])):
                i['overwrite'] = 'true'
                break
            else:
                if 'overwrite' not in i:
                    i['overwrite'] = 'false'

print(dict1)

输出：{1：{'partition_name'：'avs'，'jar'：[{'jarversion'：'1.0'，'jarname'：'jar1.jar'，'overwrite'：'true'} ，{'jarversion'：'5.0'，'jarname'：'jar5.jar'，'overwrite'：'false'}]}，2：{'partition_name'：'ivs'，'jar'：[{'jarversion '：'4.0'，'jarname'：'jar4.jar'，'overwrite'：'false'}，{'jarversion'：'2.0'，'jarname'：'jar2.jar'，'overwrite'：'true '}]}}

output: {1: {'partition_name': 'avs', 'jar': [{'jarversion': '1.0', 'jarname': 'jar1.jar', 'overwrite': 'true'}, {'jarversion': '5.0', 'jarname': 'jar5.jar', 'overwrite': 'false'}]}, 2: {'partition_name': 'ivs', 'jar': [{'jarversion': '4.0', 'jarname': 'jar4.jar', 'overwrite': 'false'}, {'jarversion': '2.0', 'jarname': 'jar2.jar', 'overwrite': 'true'}]}}
