利用档案储存选择性论点
原标题:Using a file to store optparse arguments

现在我一直在使用选择权,并想增加把论点从编织案上排出的能力。

迄今为止,我可以认为,最好用精彩的文字写法,用硬编码......似乎ky。

这样做的最合法方式是什么?

您可使用argparse 。 该单元:

>>> open( args.txt ,  w ).write( -f
bar )
>>> parser = argparse.ArgumentParser(fromfile_prefix_chars= @ )
>>> parser.add_argument( -f )
>>> parser.parse_args([ -f ,  foo ,  @args.txt ])
Namespace(f= bar )

可在斜体内列入,见pep 389

将同一指挥系统格式的论据从档案(例如:@commands)中阅读,然后使用原教区来加以整理。

options, args = parser.parse_args()

if args[0][0] ==  @ : # script.py @optfile 
    with open(args[0][1:]) as f:
        fa = [l.strip() for l in f]
    fa = fa + args[1:] # put back any other positional arguments
    # Use your original parser to parse the new options
    options, args = parser.parse_args(args=fa, values=options)
