我想将其标头转换为

的CSV文件

[“姓名”，“姓氏”，“ DOB”，“电话”，“毕业”，“专业化”，“毕业证书”，“高中名称”，“城市”，“场地详细信息” ]

以值作为'：'之后的所有值

我已经做了类似的事情：

writer = csv.writer(open('result.csv', 'a'))
writer.writerow(['Name', 'Last Name','DOB', 'Phone', 'Graduation','Specialization','Graduation Pass Out','Graduation Percentage','Higher Secondary Percentage','Higher Secondary School Name','City','Venue Details'])

with open('Name2.txt') as f:
        text = f.read()
        myarray = text.split("\n\n")
        for text1 in myarray:
            parselines(text1, writer)

def parselines(lines,writer):
    data=[]
    for line in lines.split('\n'):
        Name = line.split(": ",1)[1]
        data.append(Name)
    writer.writerow(data)

它起作用了，但是任何有效的方法都将不胜感激。

Answer 1

此算法有效（一种状态机）

如果为空行，请换一个新行
否则：添加到当前行，收集所有标题和字段

def parselines(lines):
    header = []
    csvrows = [{}]
    for line in lines:
        line = line.strip()
        if not line:
           csvrows.append({})  # new row, in dict form
        else:
           field, data = line.split(":", 1)
           csvrows[-1][field] = data
           if field not in header:
               header.append(field)
    # format CSV
    print(",".join(header))
    for row in csvrows:
        print(",".join(row.get(h,"") for h in header))
