PythonMerge詳解

一、安裝PythonMerge

1、PythonMerge是用於Python中合併字典、列表等數據類型的工具。

2、可以使用pip install python-merge進行安裝。

    pip install python-merge

3、在代碼中導入PythonMerge

    import python_merge

二、合併字典

1、合併兩個字典

使用PythonMerge可以方便地合併兩個字典。

    import python_merge
    
    dict1 = {"name": "Lucy", "age": 22}
    dict2 = {"gender": "female", "city": "Beijing"}
    
    merged_dict = python_merge.merge(dict1, dict2)
    
    print(merged_dict)

執行結果為：

    {"name": "Lucy", "age": 22, "gender": "female", "city": "Beijing"}

2、合併多個字典

PythonMerge也支持合併多個字典。

    import python_merge
    
    dict1 = {"name": "Lucy", "age": 22}
    dict2 = {"gender": "female", "city": "Beijing"}
    dict3 = {"phone": "13333333333", "address": "No. 1, Road 1"}
    
    merged_dict = python_merge.merge(dict1, dict2, dict3)
    
    print(merged_dict)

執行結果為：

    {"name": "Lucy", "age": 22, "gender": "female", "city": "Beijing", "phone": "13333333333", "address": "No. 1, Road 1"}

三、合併列表

1、合併兩個列表

PythonMerge也支持合併兩個列表。

    import python_merge
    
    list1 = [1, 2, 3]
    list2 = [4, 5, 6]
    
    merged_list = python_merge.merge(list1, list2)
    
    print(merged_list)

執行結果為：

    [1, 2, 3, 4, 5, 6]

2、合併多個列表

PythonMerge也支持合併多個列表。

    import python_merge
    
    list1 = [1, 2, 3]
    list2 = [4, 5, 6]
    list3 = [7, 8, 9]
    
    merged_list = python_merge.merge(list1, list2, list3)
    
    print(merged_list)

執行結果為：

    [1, 2, 3, 4, 5, 6, 7, 8, 9]

四、合併嵌套字典

PythonMerge還支持合併嵌套字典。

    import python_merge
    
    dict1 = {
        "id": 1,
        "name": "Lucy",
        "contacts": {
            "phone": "13333333333",
            "email": "lucy@example.com"
        }
    }
    dict2 = {
        "gender": "female",
        "contacts": {
            "phone": "14444444444",
            "address": "No. 1, Road 1"
        }
    }
    
    merged_dict = python_merge.merge(dict1, dict2)
    
    print(merged_dict)

執行結果為：

    {
        "id": 1,
        "name": "Lucy",
        "gender": "female",
        "contacts": {
            "phone": "14444444444",
            "email": "lucy@example.com",
            "address": "No. 1, Road 1"
        }
    }

五、合併嵌套列表

PythonMerge還支持合併嵌套列表。

    import python_merge
    
    list1 = [1, 2, {"name": "Lucy", "age": 22}]
    list2 = [3, {"gender": "female"}, 4]
    
    merged_list = python_merge.merge(list1, list2)
    
    print(merged_list)

執行結果為：

    [1, 2, {"name": "Lucy", "age": 22}, 3, {"gender": "female"}, 4]

六、默認合併策略

對於同一鍵的不同值，PythonMerge採用默認合併策略。

    import python_merge
    
    dict1 = {"name": "Lucy", "age": 22, "contacts": {"phone": "13333333333", "email": "lucy@example.com"}}
    dict2 = {"name": "Lucy", "age": 23, "contacts": {"phone": "14444444444", "address": "No. 1, Road 1"}}
    
    merged_dict = python_merge.merge(dict1, dict2)
    
    print(merged_dict)

執行結果為：

    {"name": "Lucy", "age": 23, "contacts": {"phone": "14444444444", "email": "lucy@example.com", "address": "No. 1, Road 1"}}

七、覆蓋合併策略

可以指定”overwrite”為True，採用覆蓋合併策略。

    import python_merge
    
    dict1 = {"name": "Lucy", "age": 22, "contacts": {"phone": "13333333333", "email": "lucy@example.com"}}
    dict2 = {"name": "Lucy", "age": 23, "contacts": {"phone": "14444444444", "address": "No. 1, Road 1"}}
    
    merged_dict = python_merge.merge(dict1, dict2, merge_strategy="overwrite")
    
    print(merged_dict)

執行結果為：

    {"name": "Lucy", "age": 23, "contacts": {"phone": "14444444444", "address": "No. 1, Road 1"}}
