python - 在Python中迭代字符串列表时搜索特定值以在字符串列表中查找匹配项

Question

我有 2 个列表。

paragraphs = [ 'The tablets are filled into cylindrically shaped bottles made of white coloured\npolyethylene. The volumes of the bottles depend on the tablet strength and amount of\ntablets, ranging from 20 to 175 ml. The screw type cap is made of white coloured\npolypropylene and is equipped with a tamper proof ring.', 'PVC/PVDC blister pack', 'Blisters are made in a cold-forming process from an aluminium base web. Each tablet is\nfilled into a separate blister and a lidding foil of aluminium is welded on. The blisters\nare opened by pressing the tablets through the lidding foil.', '\n']


final_ref = [['Blister', 'Foil', 'Aluminium'], ['Blister', 'Base Web', 'PVC/PVDC'], ['Bottle', 'Cylindrically shaped Bottles', 'Polyethylene'], ['Bottle', 'Screw Type Cap', 'Polypropylene'], ['Blister', 'Base Web', 'PVC'], ['Blister', 'Base Web', 'PVD/PVDC'], ['Bottle', 'Square Shaped Bottle', 'Polyethylene']]

下面编写的代码分隔每个段落并提取其中的匹配项。代码:

counter = 1
result=[]

for words in final_ref:
    for sen in paragraphs:
        all_exist = True
        for w in words:
            if w.lower() not in sen.lower():
                all_exist = False
                break
        if all_exist:
            #print(words[0])
            colours = ["White","Yellow","Blue","Red","Green","Black","Brown","Silver","Purple","Navy blue","Gray","Orange","Maroon","pink","colourless","blue"]
            if words[0] == 'Bottle':
                for wd in colours:
                    if wd in sen.split():
                        wd = wd

            fr = "Stage " + str(counter) + ": " + "Package Description" + ": " + sen + " Values" + ": " + str(words) + "Colour" + ": " + str(wd) + "\n" + "\n" + "\n"
            result.append(fr)
            result = [i.replace('\n','') for i in result]
            result = [i.replace('\t','') for i in result]
            counter += 1
print(result)

现在

Values: ['Blister', 'Foil', 'Aluminium']Colour: blue"] as output

当您运行此代码时，我不想要出现在第一阶段的情况。对于Stage 2和Stage 3，颜色值很好

我想检查单词[0]的值，如果其中存在“Bottle”，我想搜索该字符串中的颜色。如果没有找到，我只想退回没有任何颜色值的瓶子。该代码为我不想要的每个“阶段”提取颜色。仅当words[0]颜色中存在“Bottle”时才应搜索。关于如何解决这个问题的任何想法

预期输出:

["Group 1: Package Description: Blisters are made in a cold-forming process from an aluminium base web. Each tablet isfilled into a separate blister and a lidding foil of aluminium is welded on. The blistersare opened by pressing the tablets through the lidding foil. Values: ['Blister', 'Foil', 'Aluminium'], 


"Group 2: Package Description: The tablets are filled into cylindrically shaped bottles made of white colouredpolyethylene. The volumes of the bottles depend on the tablet strength and amount oftablets, ranging from 20 to 175 ml. The screw type cap is made of white colouredpolypropylene and is equipped with a tamper proof ring. Values: ['Bottle', 'Cylindrically shaped Bottles', 'Polyethylene']Colour: white",

这是更Pythonic的方式来做到这一点并产生预期的输出。

paragraphs = ['The tablets are filled into cylindrically shaped bottles made of white coloured\npolyethylene. The volumes of the bottles depend on the tablet strength and amount of\ntablets, ranging from 20 to 175 ml. The screw type cap is made of white coloured\npolypropylene and is equipped with a tamper proof ring.', 'PVC/PVDC blister pack', 'Blisters are made in a cold-forming process from an aluminium base web. Each tablet is\nfilled into a separate blister and a lidding foil of aluminium is welded on. The blisters\nare opened by pressing the tablets through the lidding foil.', '\n']

final_ref = [['Blister', 'Foil', 'Aluminium'], ['Blister', 'Base Web', 'PVC/PVDC'], ['Bottle', 'Cylindrically shaped Bottles', 'Polyethylene'], ['Bottle', 'Screw Type Cap', 'Polypropylene'], ['Blister', 'Base Web', 'PVC'], ['Blister', 'Base Web', 'PVD/PVDC'], ['Bottle', 'Square Shaped Bottle', 'Polyethylene']]

colours = ['White', 'Yellow', 'Blue', 'Red', 'Green', 'Black', 'Brown', 'Silver', 'Purple', 'Navy blue', 'Gray', 'Orange', 'Maroon', 'pink', 'colourless', 'blue']

TEXT_WITHOUT_COLOUR = 'Stage {counter} : Package Description: {sen} Values: {values}'

TEXT_WITH_COLOUR = TEXT_WITHOUT_COLOUR + ' Colour: {colour}'

counter = 1
result = []


def is_missing(words, sen):
    for w in words:
        if w.lower() not in sen.lower():
            return True
    return False


for words in final_ref:
    for sen in paragraphs:
        if is_missing(words, sen):
            continue

        kwargs = {
            'counter': counter,
            'sen': sen,
            'values': str(words)
        }

        if words[0] == 'Bottle':
            for wd in colours:
                if wd.lower() in sen.lower():
                    kwargs['colour'] = wd
                    break
            text_const = TEXT_WITH_COLOUR
        else:
            text_const = TEXT_WITHOUT_COLOUR

        result.append(text_const.format(**kwargs).replace('\n', '').replace('\t', ''))
        counter += 1

print(result)

输出:

["Stage 1 : Package Description: Blisters are made in a cold-forming process from an aluminium base web. Each tablet isfilled into a separate blister and a lidding foil of aluminium is welded on. The blistersare opened by pressing the tablets through the lidding foil. Values: ['Blister', 'Foil', 'Aluminium']",
