如何使material_percent得到的是字符串

在当前代码中，`material_percent` 是一个字典，其值通常是列表形式（例如 `[...]`）。如果你想将 `material_percent` 中的所有值转换为字符串，可以在写入文件之前进行相应的处理。

以下是如何修改代码以确保 `material_percent` 值是字符串：

1. **在 `ClassfyMaterials` 函数中处理 `material_percent`：**

在 `ClassfyMaterials` 函数中，添加一段代码来确保 `material_percent` 的值是字符串。可以使用 `join` 方法将列表转换为字符串，并用逗号分隔每个元素。

   def ClassfyMaterials(material_quantity, material_unit, material_word, material_percent):
       reactionMaterials = {}
       type_material_quantitys = {}
       words = []
       uncategorizes = []

       # 确保 material_percent 值是字符串
       for material, percent in material_percent.items():
           if isinstance(percent, list):
               material_percent[material] = ','.join(map(str, percent))

       # 其他代码保持不变
       material_quantity[''] = ''
       material_unit[''] = ''
       material_percent[''] = ''

       for wordList in material_word.values():
           words += wordList

       for type, words in material_word.items():
           type_material_quantitys[type] = {}

       for material, quantity in material_quantity.items():
           if quantity == '':
               quantity0 = 0
           else:
               quantity0 = deal_with_quantity(quantity)

           categorized = False
           for type, words in material_word.items():
               if material in words:
                   categorized = True
                   type_material_quantitys[type][material] = quantity0

           if not categorized:
               if material:
                   uncategorizes.append([material, quantity, material_unit[material], material_percent[material]])

       for type in material_word:
           type_material = type_material_quantitys[type]
           sortedMaterials = sorted(type_material.items(), key=lambda kv: (kv[1], kv[0]))
           sortedMaterials.reverse()

           if len(sortedMaterials) >= 3:
               material1 = sortedMaterials[0][0].replace(',', '')
               material2 = sortedMaterials[1][0].replace(',', '')
               material3 = sortedMaterials[2][0].replace(',', '')
           elif len(sortedMaterials) == 2:
               material1 = sortedMaterials[0][0].replace(',', '')
               material2 = sortedMaterials[1][0].replace(',', '')
               material3 = ''
           elif len(sortedMaterials) == 1:
               material1 = sortedMaterials[0][0].replace(',', '')
               material2 = ''
               material3 = ''
           else:
               material1 = ''
               material2 = ''
               material3 = ''

           reactionMaterials[type + '_name1'] = material1
           reactionMaterials[type + '_quantity1'] = material_quantity[material1]
           reactionMaterials[type + '_unit1'] = material_unit[material1]
           reactionMaterials[type + '_percent1'] = material_percent.get(material1, '')

           reactionMaterials[type + '_name2'] = material2
           reactionMaterials[type + '_quantity2'] = material_quantity[material2]
           reactionMaterials[type + '_unit2'] = material_unit[material2]
           reactionMaterials[type + '_percent2'] = material_percent.get(material2, '')

           reactionMaterials[type + '_name3'] = material3
           reactionMaterials[type + '_quantity3'] = material_quantity[material3]
           reactionMaterials[type + '_unit3'] = material_unit[material3]
           reactionMaterials[type + '_percent3'] = material_percent.get(material3, '')

       return reactionMaterials

2. **在写入文件时处理 `material_percent`：**

在写入文件时，确保 `material_percent` 的值已经转换为字符串。

   if __name__ == '__main__':
       # 其他代码保持不变
       for filepath in xmlFilepaths:
           try:
               uncategorizes = []
               filename = GetDOIFilename(filepath)
               with open(filepath, 'r', encoding='utf-8-sig') as file:
                   content = file.read()
                   content = modified_xml(content)
                   pH = ExtractSolutionpH(content)
                   product = ExtractProduct(content)
                   material_quantity, material_unit, material_percent = ExtractMaterials(content)
                   material_ratio1 = ExtractMaterialRatios1(content)
                   material_ratio2 = ExtractMaterialRatios2(content)
                   reactionMaterials = ClassfyMaterials(material_quantity, material_unit, material_word, material_percent)
                   if len(material_ratio1) >= len(material_ratio2):
                       reactionMaterialRatios = ClassfyMaterialsRatio(material_ratio1, materialRadio_word)
                   else:
                       reactionMaterialRatios = ClassfyMaterialsRatio(material_ratio2, materialRadio_word)
                   actionPhraseType_condition = ExtractCondition(content)
                   actionPhraseType_conditionPL = ExtractConditionPL(content)
                   actionPhraseType_conditionChecks = ExtractConditionCheck(content)
                   actionPhraseType_conditionCheck1 = []
                   list_condition = [str(x) for x in actionPhraseType_condition.values()]
                   list_conditionPL = [str(x) for x in actionPhraseType_conditionPL]
                   try:
                       for condition in actionPhraseType_conditionChecks:
                           condition = str(condition)
                           if condition not in list_condition and condition not in list_conditionPL:
                               actionPhraseType_conditionCheck1.append(condition)
                       actionPhraseType_conditionChecks = actionPhraseType_conditionCheck1
                   except:
                       pass
                   outFile.write(filename)
                   for type in material_word:
                       outFile.write(',%s,%s,%s,%s' % (
                           reactionMaterials[type + '_name1'].replace(',', ';'),
                           reactionMaterials[type + '_quantity1'],
                           reactionMaterials[type + '_unit1'],
                           reactionMaterials[type + '_percent1']
                       ))
                       outFile.write(',%s,%s,%s,%s' % (
                           reactionMaterials[type + '_name2'].replace(',', ';'),
                           reactionMaterials[type + '_quantity2'],
                           reactionMaterials[type + '_unit2'],
                           reactionMaterials[type + '_percent2']
                       ))
                       outFile.write(',%s,%s,%s,%s' % (

                           reactionMaterials[type + '_unit3'],
                           reactionMaterials[type + '_percent3']
                       ))
                   for type in materialRadio_word:
                       try:
                           outFile.write(',%s,%s' % (
                               reactionMaterialRatios['R_' + type + '_name1'].replace(',', ';'),
                               reactionMaterialRatios['R_' + type + '_quantity1']
                           ))
                           outFile.write(',%s,%s' % (

                               reactionMaterialRatios['R_' + type + '_quantity2']
                           ))
                           outFile.write(',%s,%s' % (
                               reactionMaterialRatios['R_' + type + '_name3'].replace(',', ';'),
                               reactionMaterialRatios['R_' + type + '_quantity3']
                           ))
                       except:
                           print(type)
                   for type in condition_word:
                       if type in actionPhraseType_condition:
                           condition = actionPhraseType_condition[type]
                           outFile.write(',%s,%s,%s,%s' % (condition[0], condition[1], condition[2], condition[3]))
                       else:
                           outFile.write(',%s,%s,%s,%s' % ('', '', '', ''))
                   for condition in actionPhraseType_conditionPL:
                       outFile.write(',%s,%s,%s,%s' % (condition[0], condition[1], condition[2], condition[3]))
                   check_condition = actionPhraseType_conditionChecks

           except Exception as e:
               print(traceback.print_exc())
               print(filename)

通过以上修改，`material_percent` 的值将在写入文件前被转换为字符串。这样可以确保输出文件中的 `material_percent` 列不会出现列表形式的数据。
