字典 - 如何为键和值的特定值添加条件？

Question

 my_dict =  {
      "camel": "ok",
      "test_environments": [
        {
          "Branch Coverage": "-",
          "ASIL": "ASIL-D",
          "Test Environment": "APCOM",
          "Test Configuration": "Vehicle",
          "Statement Coverage": "-",
          "Test Status": "36/36(100%)",
          "Type of Code": "handwritten",
          "MC/DC Coverage": "-",
          "Verified SW Units": "APCOM"
        },
          "Branch Coverage": "-",
          "ASIL": "ASIL-B",
          "Test Environment": "AP",
          "Test Configuration": "Per",
          "Statement Coverage": "-",
          "Test Status": "20/20(100%)",
          "Type of Code": "handwritten",
          "MC/DC Coverage": "-",
          "Verified SW Units": "APCOM"
        }
      ]
    }

我想做这样的事情：如果任何键的值为'-'并且ASIL的值为ASIL - D，将'Branch Coverage'键拆分为两个键并将它们分配给0。分支覆盖将变为：“通过的分支机构覆盖范围”：“0”和“涵盖的分支机构覆盖范围”：“0”

我正在尝试使用这段代码，但我不知道如何添加附加条件，即仅当 ASIL 为 ASIL 时这些值才变为 0 - D:

for index, _ in enumerate(my_dict['test_environments']):
    for key, values in my_dict['test_environments'][index].items():
        new_key = key.replace(" ", "_").lower()

        if '-' in values:
            value1 = 0
            value2 = 0
            my_dict['test_environments'][index]['branch_coverage' + '_passed'] = value1
            my_dict['test_environments'][index]['branch_coverage' + '_covered'] = value2

Answer 1

我不确定你到底想要什么。如果你想用 0 替换'-'，你可以像这样循环：

my_dict =  {
      "camel": "ok",
      "test_environments": [
        {
          "Branch Coverage": "-",
          "ASIL": "ASIL-D",
          "Test Environment": "APCOM",
          "Test Configuration": "Vehicle",
          "Statement Coverage": "-",
          "Test Status": "36/36(100%)",
          "Type of Code": "handwritten",
          "MC/DC Coverage": "-",
          "Verified SW Units": "APCOM"
        }
      ]
    }

for dic in my_dict['test_environments']:
    for key in dic:
        if dic[key] == '-':
            dic[key] = 0

Answer 2

for dic in dictionary:
    for key in dic:
        if dic[key] == '-':
            dic[key] = 0

Answer 3

IIUC，你可以使用：

选项 1：用新条目替换旧条目

for index, env in enumerate(my_dict['test_environments']):
    if env['ASIL'] == 'ASIL-D':
        data = {}
        for key, val in env.items():
            if env[key] == '-':
                data[f"{key} Passed"] = 0
                data[f"{key} Convered"] = 0
            else:
                data[key] = val
        my_dict['test_environments'][index] = data.copy()

print(my_dict)

# Output
 'test_environments': [{'Branch Coverage Passed': 0,
   'Branch Coverage Convered': 0,
   'ASIL': 'ASIL-D',
   'Test Environment': 'APCOM',
   'Test Configuration': 'Vehicle',
   'Statement Coverage Passed': 0,
   'Statement Coverage Convered': 0,
   'Test Status': '36/36(100%)',
   'Type of Code': 'handwritten',
   'MC/DC Coverage Passed': 0,
   'MC/DC Coverage Convered': 0,
   'Verified SW Units': 'APCOM'}]}

选项 2：向当前条目添加新值

for env in my_dict['test_environments']:
    if env['ASIL'] == 'ASIL-D':
        data = {}
        for key, val in env.items():
            if env[key] == '-':
                data[f"{key} Passed"] = 0
                data[f"{key} Convered"] = 0
            else:
                data[key] = val
        env.update(data)

print(my_dict)

# Output
{'camel': 'ok',
 'test_environments': [{'Branch Coverage': '-',
   'ASIL': 'ASIL-D',
   'Test Environment': 'APCOM',
   'Test Configuration': 'Vehicle',
   'Statement Coverage': '-',
   'Test Status': '36/36(100%)',
   'Type of Code': 'handwritten',
   'MC/DC Coverage': '-',
   'Verified SW Units': 'APCOM',
   'Branch Coverage Passed': 0,
   'Branch Coverage Convered': 0,
   'Statement Coverage Passed': 0,
   'Statement Coverage Convered': 0,
   'MC/DC Coverage Passed': 0,
   'MC/DC Coverage Convered': 0}]}

Answer 4

这确实是你所说的你想要发生的事情（我认为）：

示例数据：

my_dict =  {
      "camel": "ok",
      "test_environments": [
        {
          "Branch Coverage": "-",
          "ASIL": "ASIL-D",
          "Test Environment": "APCOM",
          "Test Configuration": "Vehicle",
          "Statement Coverage": "-",
          "Test Status": "36/36(100%)",
          "Type of Code": "handwritten",
          "MC/DC Coverage": "-",
          "Verified SW Units": "APCOM"
        },
        {
          "Branch Coverage": "-",
          "ASIL": "ASIL-B",
          "Test Environment": "AP",
          "Test Configuration": "Per",
          "Statement Coverage": "-",
          "Test Status": "20/20(100%)",
          "Type of Code": "handwritten",
          "MC/DC Coverage": "-",
          "Verified SW Units": "APCOM"
        }
      ]
    }

代码：

import json  # For printing result.

for test_env in my_dict['test_environments']:
    if(test_env['ASIL'] == 'ASIL-D' and
       any(['-' in value for value in test_env.values()])):
        for key, value in test_env.items():
            if value == '-':
                test_env['branch_coverage' + '_passed'] = 0
                test_env['branch_coverage' + '_covered'] = 0

print('Result:')
print(json.dumps(my_dict, indent=4, sort_keys=True))

输出：

Result:
{
    "camel": "ok", 
    "test_environments": [
        {
            "ASIL": "ASIL-D", 
            "Branch Coverage": "-", 
            "MC/DC Coverage": "-", 
            "Statement Coverage": "-", 
            "Test Configuration": "Vehicle", 
            "Test Environment": "APCOM", 
            "Test Status": "36/36(100%)", 
            "Type of Code": "handwritten", 
            "Verified SW Units": "APCOM", 
            "branch_coverage_covered": 0, 
            "branch_coverage_passed": 0
        }, 
        {
            "ASIL": "ASIL-B", 
            "Branch Coverage": "-", 
            "MC/DC Coverage": "-", 
            "Statement Coverage": "-", 
            "Test Configuration": "Per", 
            "Test Environment": "AP", 
            "Test Status": "20/20(100%)", 
            "Type of Code": "handwritten", 
            "Verified SW Units": "APCOM"
        }
    ]
}
