Python 无法相应地打印结果并将相同的结果写入csv文件

我试图根据字典中的

类别名称来解析一些
类别的值。我从这本词典中选择要解析的类别名称是
内部功能
和
空间和便利设施
。下面的脚本可以解析它们，但当我试图打印它们时，输出的对齐变得混乱，这显然会在我编写它们时对csv文件产生类似的影响

如何以正确的方式打印结果并将其写入csv文件

以下是供您考虑的内容：

[{'categoryGroupName': 'Interior Features', 'categories': [{'categoryName': 'Bedrooms', 'categoryFacts': [{'factLabel': 'Beds', 'factValue': '3'}, {'factLabel': 'Master bedroom location', 'factValue': 'Main'}]}, {'categoryName': 'Kitchen', 'categoryFacts': [{'factLabel': 'Kitchen location', 'factValue': 'Main'}]}, {'categoryName': 'Other Rooms', 'categoryFacts': [{'factLabel': 'Dining room location', 'factValue': 'Main'}, {'factLabel': 'Living room location', 'factValue': 'Main'}, {'factLabel': 'Utility room location', 'factValue': 'Lower'}]}, {'categoryName': 'Heating and Cooling', 'categoryFacts': [{'factLabel': 'Heating', 'factValue': 'Forced air'}, {'factLabel': 'Heating', 'factValue': 'Gas'}, {'factLabel': 'Heating and cooling', 'factValue': '90%+ High Efficiency, Forced Air'}]}, {'categoryName': 'Basement', 'categoryFacts': [{'factLabel': None, 'factValue': 'Partially finished'}, {'factLabel': None, 'factValue': '900 sqft basement'}, {'factLabel': 'Basement', 'factValue': 'Partially Finished'}]}, {'categoryName': 'Attic', 'categoryFacts': [{'factLabel': None, 'factValue': 'Attic'}]}, {'categoryName': 'Appliances', 'categoryFacts': [{'factLabel': 'Appliances included', 'factValue': 'Dishwasher, Dryer, Microwave, Range / Oven, Refrigerator, Washer'}, {'factLabel': 'Appliances that stay', 'factValue': 'Range/Oven, Dishwasher, Refrigerator, Washer, Dryer'}]}, {'categoryName': 'Flooring', 'categoryFacts': [{'factLabel': 'Floor size', 'factValue': '2,070 sqft'}, {'factLabel': 'Flooring', 'factValue': 'Carpet, Hardwood, Tile'}, {'factLabel': 'Floor covering', 'factValue': 'Hardwood, Laminate, Wall to Wall Carpet'}]}, {'categoryName': 'Other Interior Features', 'categoryFacts': [{'factLabel': 'Addition size', 'factValue': '900'}, {'factLabel': None, 'factValue': 'Fireplace'}, {'factLabel': None, 'factValue': 'Ceiling Fan'}, {'factLabel': 'Features', 'factValue': 'Dbl Pane/Storm Windw, Dining Room, Security System, Ceiling Fan(s), Hot Tub/Spa'}]}]}, {'categoryGroupName': 'Building', 'categories': [{'categoryName': 'Other Building Features', 'categoryFacts': [{'factLabel': 'Building info', 'factValue': 'Built On Lot'}]}]}, {'categoryGroupName': 'Spaces and Amenities', 'categories': [{'categoryName': 'Size', 'categoryFacts': [{'factLabel': 'Unit count', 'factValue': '1'}]}, {'categoryName': 'Spaces', 'categoryFacts': [{'factLabel': None, 'factValue': 'Hot Tub/Spa'}]}, {'categoryName': 'Amenities', 'categoryFacts': [{'factLabel': None, 'factValue': 'Security System'}]}]}, {'categoryGroupName': 'Construction', 'categories': [{'categoryName': 'Type and Style', 'categoryFacts': [{'factLabel': 'Structure type', 'factValue': 'Craftsman'}, {'factLabel': None, 'factValue': 'Single Family'}, {'factLabel': 'Architecture', 'factValue': 'Craftsman'}, {'factLabel': 'Entrance level', 'factValue': 'Main'}, {'factLabel': 'Style', 'factValue': '16 -

我尝试过的脚本：

name = "property in somewhere"

for elem in desc:

    if elem['categoryGroupName']=='Interior Features':
        interior_features = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
        interior_features = str(interior_features).replace("{","").replace("}","").replace("'","")
    else:
        interior_features = ""

    if elem['categoryGroupName']=='Spaces and Amenities':
        space_amenities = {curr['factLabel']: curr['factValue'] for i in elem['categories'] for curr in i['categoryFacts']}
        space_amenities = str(space_amenities).replace("{","").replace("}","").replace("'","")
    else:
        space_amenities = ""

    print(name,interior_features,space_amenities)

结果我得到：

property in somewhere Beds: 3, Master bedroom location: Main, Kitchen location: Main, Dining room location: Main, Living room location: Main, Utility room location: Lower, Heating: Gas, Heating and cooling: 90%+ High Efficiency, Forced Air, None: Ceiling Fan, Basement: Partially Finished, Appliances included: Dishwasher, Dryer, Microwave, Range / Oven, Refrigerator, Washer, Appliances that stay: Range/Oven, Dishwasher, Refrigerator, Washer, Dryer, Floor size: 2,070 sqft, Flooring: Carpet, Hardwood, Tile, Floor covering: Hardwood, Laminate, Wall to Wall Carpet, Addition size: 900, Features: Dbl Pane/Storm Windw, Dining Room, Security System, Ceiling Fan(s), Hot Tub/Spa

在上面的输出中，您可以看到，某处的这一行
属性已打印多次，而它应该打印一次。这一行<代码>单位计数：1，无：安全系统应该在第三列，而它已经放置了一些不需要的区域

底线是上面的脚本应该打印一次结果，但由于for循环，它会打印多次

预期输出（将变量名粘贴在此处，而不是将其值粘贴在此处，以使您了解对齐方式）。更清楚的是，b行、c行等没有结果。结果应打印一次，并限于第A1行、第B1行和第C1行。句号

Column A    Column B             Column C
name        interior_features    space_amenities

代码的两个mod：

（1） 根据每列的最大宽度左对齐每个字段

（2） 不要打印与所需类别不匹配的类别（即返回empy功能的类别）

输出

如果我理解正确，目标是从
desc
中的项目中获取某些值。每个值可能存在一次，也可能根本不存在-在这种情况下，结果应为“N/A”。因此，您可以使用带有N/a默认值的字典，然后用
desc
列表中的值替换它们

字典的值。然后附加在
desc
列表中找到的值。最后，如果列表中有值，则将它们连接成字符串，如果没有，则将空列表替换为“N/a”

如果要将
行
字典转换为列表，可以使用
行.values（）
。您还可以使用
csv.DictWriter（）
将结果写入文件，而无需将其转换为列表

import csv

with open('file.csv', 'w', encoding='utf-8', newline='') as f:
    w = csv.DictWriter(f, rows.keys())
    w.writeheader()
    w.writerow(rows)

你肯定误解了我所期望的结果。查看编辑csv输出。我从来没有说过我解析字段的方式是实现这一点的理想方式。如果出现更好的逻辑，解析逻辑总是可以被纠正以去除那些制表符和空格。谢谢.@robots.txt--谢谢您的澄清。我相应地修改了我的答案。@robots.txt--误解是您将其称为CSV文件，通常不需要对齐文本进行显示（例如，可以使用选项卡来标识每个字段）。我在字段之间放置了一个选项卡，因此尽管有额外的空间使其列对齐，但仍然可以将其作为CSV处理。@robots.txt--多次打印“某处的属性”的原因是您有10个类别，即：[‘内部特征’、‘建筑’、‘空间和设施’、‘建筑’、‘外部特征’、‘社区和邻里’、‘停车’、‘公用设施’、‘其他’、‘Zillow上的活动’]。其中只有两个与您的筛选器匹配并具有数据，而其他的则为内饰和空间设施打印空字符串。嘿，robots.txt，很高兴再次见到您。如果我理解正确，每个
desc
列表都应该有一个
内饰功能
项和一个
空间设施
项。如果是这样，您可以创建一个包含
名称
值的列表，当您找到
内部设施
或
空间设施
值时，将其添加到列表中。循环结束时，您应该有一个包含三项的列表：
[名称、内部设施、空间设施]
您可以打印或保存到文件中。如果有不清楚的地方，或者我误解了问题，请告诉我。您好@t.m.adam，很高兴在循环中找到您。如果您检查，您可以发现我的纠正方法符合您的建议。请通读。谢谢。好的，在这种情况下，您可以使用默认为N/a的词典值（例如：
rows={'name'：name，'interior_features'：'N/A'，'space_facilities'：'N/A'，'virtual_stuff'：'N/A'}
）。当您找到一个项时，将其添加到字典中；如果没有项，字典键将具有默认值-N/A。您可以使用
dict.values（）
在列表中获取字典值。这个想法似乎很有希望@t.m.adam。问题是我真的找不到任何关于如何在脚本中实现它的想法，因为我在处理字典内容方面远远落后。最后，我能够说服你用python问题写一个答案。保持冷静，直到下一个麻烦。哈！祝2020年万事如意！谢谢。忘了问一个非常不相关的问题。你有选择深入研究scrapy吗？没有，我根本不使用scrapy。现在，我也有一个问题。一个值是否可能在
desc
列表中出现多次？如果有，我的代码可能有问题，因为
rows
键将仅具有最后一个值。
import csv

    w.writeheader()
    w.writerow(rows)
