如何连接多行由\

Question

我想筛选以RUN开头并用\e分隔的行

RUN install-repository \
    "--url http://toolshed.g2.bx.psu.edu/ -o iuc --name gatk2 --panel-section-name GATK2" \
    "--url http://toolshed.g2.bx.psu.edu/ -o devteam --name suite_samtools_0_1_19 --panel-section-name SAMTools" \
    "--url http://toolshed.g2.bx.psu.edu/ -o devteam --name freebayes --panel-section-name Freebayes"

RUN ...

在我得到的那一刻

RUN install-repository \
RUN install-repository \
...

代码如下：

import urllib2

def run():

    file_url = "https://raw.githubusercontent.com/bgruening/docker-recipes/master/galaxy-exom-seq/Dockerfile"

    data = urllib2.urlopen(file_url)

    for line in data:
        if line.startswith("RUN"):
            print line.rstrip()

if __name__ == '__main__':
    run()

最好的方法是什么？你知道吗

没有看到这个答案被接受，所以我会尝试一下。你知道吗

from urllib import urlopen
import re

def run():
    re1 = '^RUN'
    re2 = '^    " url'
    file_url = "https://raw.githubusercontent.com/bgruening/docker-recipes/master/galaxy-exom-seq/Dockerfile"
    data = urlopen(file_url)
    for line in data:
        if re.search(re1, line) or re.search(re2, line):
            print(line.rstrip('\\\n'))

if __name__ == '__main__':
    run()

我想我会明白的。你知道吗
