CSV文件未正确填充详细信息

Question

import csv
TextFileContent = open('tickets.txt')
with open('example4.csv', 'w') as csvfile:
    fieldnames = ['Author', 'ticket number', 'Revision']
    writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
    writer.writeheader()
    for TextLine in TextFileContent:
        if 'Revision:' in TextLine:
            tmp=TextLine.replace('Revision:', "")
            print(tmp)
            writer.writerow({'Revision': tmp})
        elif 'Author:' in TextLine:
            tmp=TextLine.replace("Author:", "")
            print(tmp)
            writer.writerow({'Author': tmp})
        elif 'Contributes to:' in TextLine:
            tmp=TextLine.replace("Contributes to:", "")
            print(tmp)
            writer.writerow({'ticket number': tmp})

嗨，我已经开发了上述python脚本，从文本文件中提取“作者”、“票证”和“修订版”的详细信息，然后将这些信息填充到CSV文件中

现在我可以提取所有信息，但数据没有正确填写在CSV文件

文本文件内容如下所示

Revision: 22904
Author: Userx
Contributes to: CF-1159


Revision: 22887
Author: Usery
Contributes to: CF-955


Revision: 22884
Author: UserZ
Contributes to: CPL-7768

我想在CSV文件的结果如下

Author  ticket number   Revision
Userx    CF-1159        22904
Usery    CF-955         22887
UserZ    CPL-7768       22884

您的代码在找到任何字段时立即写入一行，而不是等到它读取了一整套字段。下面的编辑等待完整的集合，然后写入行

with open('/tmp/out.csv', 'w') as csvfile:
    fieldnames = ['Author', 'ticket number', 'Revision']
    writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
    writer.writeheader()
    row = {}
    for TextLine in TextFileContent:
        if 'Revision:' in TextLine:
            row['Revision'] = TextLine.replace('Revision: ', "")
        elif 'Author:' in TextLine:
            row['Author'] = TextLine.replace("Author: ", "")
        elif 'Contributes to:' in TextLine:
            row['ticket number'] = TextLine.replace("Contributes to: ", "")
        if len(row) == len(fieldnames):
            writer.writerow(row)
            row = {}

请注意，除非所有记录都包含所有字段，否则这将无法正常工作
