Question

我的python代码在bash脚本中调用，而python脚本也需要bash循环的输入参数。但我不确定这样做的最好方法。这是我的尝试：

bash代码：

cat filelList.txt | while read i;#file1List.txt stores file names
do
python script.py $i > $i.txt
done

我不确定的蟒蛇：

file = sys.argv[0] # not sure about this
in = open(file)
for line in iter(in): # not sure about this
    do something.......

有谁知道写这3条python线的最佳方法？谢谢

为什么不在python中做所有事情？假设您有一个文件夹，您必须处理每个文件：

import sys
import os

assert os.path.isdir(sys.argv[1])
listing = os.listdir(sys.argv[1])

for filename in listing:
    with open(sys.argv[1]+"/"+filename,'r') as f:

        for line in f:
            #do something                                                                                                                                                                                                                    
            pass

或者，如果您有一个包含要处理的其他文件列表的文件：

import sys
import os

assert os.path.isfile(sys.argv[1])

with open(sys.argv[1]) as filelist:
    filenames = [line.strip() for line in filelist]
    for filename in filenames:
        if not os.path.isfile(filename):
            print >> sys.stderr , "{0} is not a valid file".format(filename)
            break
        with open(filename,'r') as f:
            for line in f:
                #do something                                                                                                                                                                                                                
                pass

调用需要bash for loop内输入的python脚本
