我試過很多方法來輸出保存到文本文件,但它不適合我如何保存蟒蛇輸出到文本文件
工作,這是代碼
from optparse import OptionParser
import os.path
import re
regex = re.compile(("([a-z0-9!#$%&'*+\/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+\/=?^_`"
"{|}~-]+)*(@|\sat\s)(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?(\.|"
"\sdot\s))+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)"))
def file_to_str(filename):
"""Returns the contents of filename as a string."""
with open(filename) as f:
return f.read().lower() # Case is lowered to prevent regex mismatches.
def get_emails(s):
"""Returns an iterator of matched emails found in string s."""
# Removing lines that start with '//' because the regular expression
# mistakenly matches patterns like 'http://[email protected]' as '//[email protected]'.
return (email[0] for email in re.findall(regex, s) if not email[0].startswith('//'))
if __name__ == '__main__':
parser = OptionParser(usage="Usage: python %prog [FILE]...")
# No options added yet. Add them here if you ever need them.
options, args = parser.parse_args()
if not args:
parser.print_usage()
exit(1)
for arg in args:
if os.path.isfile(arg):
for email in get_emails(file_to_str(arg)):
print email
else:
print '"{}" is not a file.'.format(arg)
parser.print_usage()
當您運行腳本
它將打印電子郵件在DOS屏幕
我想將它保存爲文本文件

看起來你希望我們爲你寫一些代碼。儘管許多用戶願意爲遇險的編碼人員編寫代碼,但他們通常只在海報已嘗試自行解決問題時才提供幫助。展示這一努力的一個好方法是包含迄今爲止編寫的代碼,示例輸入(如果有),預期輸出以及實際獲得的輸出(控制檯輸出,回溯等)。您提供的細節越多,您可能會收到的答案就越多。檢查[FAQ](http://stackoverflow.com/tour)和[如何提問](http://stackoverflow.com/help/how-to-ask)。 –
