python - 是否有可能将熊猫数据框的每一行转换为预定义的文本文件？

问题描述

我的数据框如下所示：

数据框 我希望将每一行插入到预定义的文本文件中，以便这些值在文档中具有特定的位置。这就是我想出的：

for i in range(len(df)):
with open("%s.xml" %index, "w") as f:
    f.write(
     """<?xml version="1.0"?>
<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ccts="urn:un:unece:uncefact:documentation:2" xsi:schemaLocation="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2 http://docs.oasis-open.org/ubl/os-UBL-2.1/xsd/maindoc/UBL-Invoice-2.1.xsd">
  <cbc:UBLVersionID>2.1</cbc:UBLVersionID>
  <cbc:CustomizationID>urn:www.cenbii.eu:transaction:biitrns010:ver2.0:extended:urn:www.peppol.eu:bis:peppol4a:ver2.0:extended:urn:www.simplerinvoicing.org:si:si-ubl:ver1.1.x</cbc:CustomizationID>
  <cbc:ProfileID>urn:www.cenbii.eu:profile:bii04:ver2.0</cbc:ProfileID>
  <cbc:ID> """df[Factuurdatum[i]]" </cbc:ID>
  <cbc:IssueDate> Totaal </cbc:IssueDate>
  <cbc:DueDate> Factuurdatum[i] </cbc:DueDate>"
  <cbc:InvoiceTypeCode listID="UNCL1001" listAgencyID="6">380</cbc:InvoiceTypeCode>
  <cbc:DocumentCurrencyCode>EUR</cbc:DocumentCurrencyCode>
  <cac:AccountingSupplierParty>

我的理想输出将是第一行：

<?xml version="1.0"?>
    <Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ccts="urn:un:unece:uncefact:documentation:2" xsi:schemaLocation="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2 http://docs.oasis-open.org/ubl/os-UBL-2.1/xsd/maindoc/UBL-Invoice-2.1.xsd">
      <cbc:UBLVersionID>2.1</cbc:UBLVersionID>         <cbc:CustomizationID>urn:www.cenbii.eu:transaction:biitrns010:ver2.0:extended:urn:www.peppol.eu:bis:peppol4a:ver2.0:extended:urn:www.simplerinvoicing.org:si:si-ubl:ver1.1.x</cbc:CustomizationID>
      <cbc:ProfileID>urn:www.cenbii.eu:profile:bii04:ver2.0</cbc:ProfileID>
      <cbc:ID> ""0606194584" </cbc:ID>
      <cbc:IssueDate> 12.93 </cbc:IssueDate>
      <cbc:DueDate> 2020-09-18 </cbc:DueDate>"
      <cbc:InvoiceTypeCode listID="UNCL1001" listAgencyID="6">380</cbc:InvoiceTypeCode>
      <cbc:DocumentCurrencyCode>EUR</cbc:DocumentCurrencyCode>
      <cac:AccountingSupplierParty>

然后我的理想输出将是第二行：

<?xml version="1.0"?>
    <Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2" xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2" xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ccts="urn:un:unece:uncefact:documentation:2" xsi:schemaLocation="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2 http://docs.oasis-open.org/ubl/os-UBL-2.1/xsd/maindoc/UBL-Invoice-2.1.xsd">
      <cbc:UBLVersionID>2.1</cbc:UBLVersionID>         <cbc:CustomizationID>urn:www.cenbii.eu:transaction:biitrns010:ver2.0:extended:urn:www.peppol.eu:bis:peppol4a:ver2.0:extended:urn:www.simplerinvoicing.org:si:si-ubl:ver1.1.x</cbc:CustomizationID>
      <cbc:ProfileID>urn:www.cenbii.eu:profile:bii04:ver2.0</cbc:ProfileID>
      <cbc:ID> ""20200633369" </cbc:ID>
      <cbc:IssueDate> 30.25 </cbc:IssueDate>
      <cbc:DueDate> 2020-06-26 </cbc:DueDate>"
      <cbc:InvoiceTypeCode listID="UNCL1001" listAgencyID="6">380</cbc:InvoiceTypeCode>
      <cbc:DocumentCurrencyCode>EUR</cbc:DocumentCurrencyCode>
      <cac:AccountingSupplierParty>

每行等等。有什么可能的方法来做到这一点？有人能帮我吗？

解决方案

你快到了。您可以使用字符串格式将值插入字符串中，如下所示：

data = "some data i want to insert"

result = "This is what I want to say: {}".format(data)
# or
result = f"This is what I want to say: {data}"
