当我从命令行执行我的python脚本时,我没有这样的问题:

[rv @ med240-183 db] $ python formatdb.py
[rv @ med240-183 db] $

当我每隔午夜尝试使用crontab运行脚本时,我会遇到一系列错误:

import: unable to open X server `' @ import.c/ImportImageCommand/367.
/home/rv/ncbi-blast-2.2.23+/db/formatdb.py: line 2: from: command not found
/home/rv/ncbi-blast-2.2.23+/db/formatdb.py: line 3: from: command not found
import: unable to open X server `' @ import.c/ImportImageCommand/367.
/home/rv/ncbi-blast-2.2.23+/db/formatdb.py: line 6: syntax error near
unexpected token `('
/home/rv/ncbi-blast-2.2.23+/db/formatdb.py: line 6: `conx = MySQLdb.connect
(user = 'root', passwd = '******', db = 'vaxijen_antigens')'

我的脚本目录如下:

/home/rv/ncbi-blast-2.2.23+/db/

Crontab看起来像:

SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/bin/python/:/home/rv/ncbi-blast-2.2.23+/database_backup:/home/rv/ncbi-blast-2.2.23+/db/
MAILTO="******"
HOME=/

# For details …

所以目前我正在尝试删除目录中列出的1分钟旧文件,我将在脚本工作后更改该值.
下面的代码返回错误:AttributeError: 'str' object has no attribute 'mtime'

import time
import os 
#from path import path

seven_days_ago = time.time() - 60
folder = '/home/rv/Desktop/test'

for somefile in os.listdir(folder):
    if int(somefile.mtime) < seven_days_ago:
        somefile.remove()

我正在使用以下脚本向自己发送电子邮件，该脚本运行正常，没有错误，但我没有收到任何电子邮件。

import smtplib

sender = 'foo@hotmail.com'
receivers = ['foo@hotmail.com']

message = """From: From Person <foo@hotmail.com>
To: To Person <foo@hotmail.com>
Subject: SMTP e-mail test

This is a test e-mail message.
"""

try:
   smtpObj = smtplib.SMTP('localhost')
   smtpObj.sendmail(sender, receivers, message)         
   print "Successfully sent email"
except SMTPException:
   print "Error: unable to send email"

编辑

脚本名为 test.py

所以我有一个看起来像这样的文件:

#!/usr/bin/python
import MySQLdb
import subprocess
from subprocess import call
import re

conx = MySQLdb.connect (user = 'root', passwd = '******', db = 'vaxijen_antigens')
cursor = conx.cursor()
cursor.execute('select * from sequence')
row = cursor.fetchall()

f = open('/home/rv/ncbi-blast-2.2.23+/db/vdatabase.fasta', 'w')

for i in row:
    f.write('>'+i[0].strip()+'\n')
    s = re.sub(r'[^\w]','',str(i[1]))
    s = ''.join(s)
    for k in range(0, len(s), 60):
        f.write('%s\n' % (s[k:k+60]))
    f.write('\n')

f.close()

subprocess.call(['formatdb', '-p', 'T', '-i', r'/home/rv/ncbi-blast-2.2.23+/db/vdatabase.fasta'])

该文件从命令行运行没有问题,但当我尝试使用crontab运行它时,我收到此错误:

  File "/home/rv/ncbi-blast-2.2.23+/db/formatdb.py", line 29, in <module>
    subprocess.call(['formatdb', '-p', 'T', '-i',
r'/home/rv/ncbi-blast-2.2.23+/db/vdatabase.fasta'])
OSError: [Errno 2] …

Python脚本可以将照片上传到照片存储桶,然后检索它的URL吗？是这样怎么样？

我在这个链接上找到了一个脚本:http://www.democraticunderground.com/discuss/duboard.php？az = view_all&address = 240x677

但我发现这令人困惑.

非常感谢,
