用于打印nmail的循环

Question

在邮件中，有以下行。这些行将被转换为单行基于＆＃34; List Num＆＃34; 。对于打印，以下代码是工作。但是当我尝试将变量存储为列表或字符串时，它无法正常工作。已经给出了以下代码。

mail = mailbody.splitlines()
nmail = ""
lnflg = "yes"
for line in mail:
    if re.findall(r'List Num:\s*([A-Z][0-9]{5}[A-Z]*)', line) != []:
        lnflg = "no"
        print "\n"
    if lnflg == "no":
        print line.rstrip(os.linesep),
    else:
        print line

如果我使用for循环

打印，则下面的代码无法正常工作

mail = mailbody.splitlines()
nmail = ""
lnflg = "yes"
for line in mail:
    if re.findall(r'List Num:\s*([A-Z][0-9]{5}[A-Z]*)', line) != []:
        lnflg = "no"
        #print "\n"
        nmail = nmail + "\n"
    if lnflg == "no":
        #print line.rstrip(os.linesep),
        nmail = nmail + line.rstrip(os.linesep)
    else:
        nmail = nmail + line

for ln in nmail:
    print ln

Answer 1

您可以使用BARCODE行来分隔groupby：

from itertools import groupby
with open("foo.txt") as f:
    grouped, data = groupby(map(str.rstrip,f), key=lambda x: x.strip().startswith("BARCODE")), []
    for k,v in grouped:
        if not k:
            data.append("".join(v)+"".join(next(grouped)[1]))


print(data[0])
print()
print(data[1])

输入：
