Question

我有多行电子邮件，我需要做几件事：

stephen.marquard@uct.ac.za
louis@media.berkeley.edu
zqian@umich.edu
rjlowe@iupui.edu
zqian@umich.edu
rjlowe@iupui.edu 
... etc

我需要将它们放在一个列表中：['stephen.marquard@uct.ac.za','louis@media.berkeley.edu','louis@media.berkeley.edu' ..等]

需要弄清楚哪个电子邮件是该列表中最重复的，这就是我启动代码的方式，我希望我可以从我的代码结束处完成它！

fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
lines = []
count = 0 # For next step
for line in fh:
    line = line.rstrip()
    if not line.startswith("From ") : continue
    x = line.split()
    emails = x[1]
 #print y

maxapperence = 0 
famous = None
for mail in emails:
    count = emails.count(mail)
    if count > maxapperence:
        famous = mail
print famous

apparence = dict()
for mail in set(emails):
    apparence[mail] = emails.count(mail)
print apparence]

out put：

stephen.marquard@uct.ac.za
louis@media.berkeley.edu
zqian@umich.edu
rjlowe@iupui.edu
zqian@umich.edu
rjlowe@iupui.edu

Answer 1

如果您的文件只包含电子邮件地址：

import collections
filename = ''
c = collections.Counter(map(str.strip, open(filename).readlines()))
print(c.most_common(10)) # dumb example of possible output format

Answer 2

第一个例子

emails = """stephen.marquard@uct.ac.za
louis@media.berkeley.edu
zqian@umich.edu
rjlowe@iupui.edu
zqian@umich.edu
rjlowe@iupui.edu
cwen@iupui.edu
cwen@iupui.edu
gsilver@umich.edu
gsilver@umich.edu
zqian@umich.edu
gsilver@umich.edu
wagnermr@iupui.edu
zqian@umich.edu
antranig@caret.cam.ac.uk
gopal.ramasammycook@gmail.com
david.horwitz@uct.ac.za
david.horwitz@uct.ac.za
david.horwitz@uct.ac.za
david.horwitz@uct.ac.za
stephen.marquard@uct.ac.za
louis@media.berkeley.edu
louis@media.berkeley.edu
ray@media.berkeley.edu
cwen@iupui.edu
cwen@iupui.edu
cwen@iupui.edu""".split("\n")

maxapperence = 0 
famous = None
for mail in set(emails):
    count = emails.count(mail)
    if count > maxapperence:
        famous = mail
        maxapperence = count
print famous, maxapperence

您还可以存储所有邮件表情

apparence = dict()
for mail in set(emails):
    apparence[mail] = emails.count(mail)
print apparence

将多行添加到一个列表中？
