如何从字符串末尾删除逗号？我试过了
awk = subprocess.Popen([r"awk", "{print $10}"], stdin=subprocess.PIPE)
awk_stdin = awk.communicate(uptime_stdout)[0]
print awk_stdin
temp = awk_stdin
t = temp.strip(",")
也尝试过t = temp.rstrip(","),两个都不行.
这是代码:
uptime = subprocess.Popen([r"uptime"], stdout=subprocess.PIPE)
uptime_stdout = uptime.communicate()[0]
print uptime_stdout
awk = subprocess.Popen([r"awk", "{print $11}"], stdin=subprocess.PIPE)
awk_stdin = awk.communicate(uptime_stdout)[0]
print repr(awk_stdin)
temp = awk_stdin
tem = temp.rstrip("\n")
logfile = open('/usr/src/python/uptime.log', 'a')
logfile.write(tem + "\n")
logfile.close()
这是输出:
17:07:32 up 27 days, 37 min, 2 users, load average: 5.23, 5.09, 4.79
5.23,

File …是否可以将while循环中的变量存储到函数中,然后在循环结束时从函数中调用该变量
例如:在while循环期间,问题在于当我尝试从store()检索变量时它失败了...因为它需要传递参数.
def store(a,b,c):
x1 = a
y1 = b
z1 = c
return (x1,y1,z1)
def main():
while condition:
x = .......
y = .......
z = .......
......
......
store(x,y,z) #store to function...
......
......
......
s1,s2,s3 = store()
......
......
......
我正在给定一组文件上运行for循环.为了监视目的,它写入当前正在处理文件的输出.
sys.stdout.write("\rProcessing.... "+ j)
sys.stdout.flush()
其中j是文件名
脚本输出......
Processing.... /etc/sysconfig/rhn/sources0.examplewn-slepcsbals-ipv6f
问题是回车"\ r \n"没有清楚地清除以前的文件名并且上面有文件名.
任何想法我如何解决这个问题......并使其更加清晰

import …我有一个像csv的数据库
apple,10,red,date
orange,12,yellow,date
pear,13,green,date
pineapple,14,brown,date
我想首先搜索例如:菠萝然后获得第三列"从它,我需要一些想法,我使用python csv模块
我能得到
#!/usr/bin/env python
import csv
import sys
file = open("/tmp/database.txt", 'rt')
reader = csv.reader(file)
for i in reader:
print i
输出:
['apple', '10', 'red', 'date']
['orange', '12', 'yellow', 'date']
['pear', '13', 'green', 'date']
['pineapple', '14', 'brown', 'date']
我正在尝试将日期字符串转换为日期格式

然而,当年份是两位数时,它会中断
>>> str = "04-18-02 03:50PM"
>>> time.strptime(str, '%m-%d-%Y %H:%M%p')
Traceback (most recent call last):

有任何想法吗？？

例如,我有cisco日志和Web服务器日志,我想按行过滤特定值并输入hadoop.

是否可以在"map"阶段过滤行,即程序将从HDFS中的文件中读取行并将其发送到mapper ...
我需要一些关于最佳方式和清洁方式的建议....
谢谢.
