Question

是否可以使用字典缩短项目代码，因为一旦用户使用命令行参数“--template1”或1-4范围内的其他数字执行程序，它会将当前页眉，页脚分配给根据给定的命令行参数号在各自路径中预定义的文件。我想知道是否可以在字典中添加这些文件或以某种方式缩短这100行？

if len(sys.argv) == 2:
    all_templates = ('--template1', '--template2', '--template3', '--template4')
    if not sys.argv[1].startswith(all_templates):
        sys.exit("""Usage:  python build.py --template1

""")
    if sys.argv[1].startswith('--'):
        option = sys.argv[1][2:]
        if option == 'template1':

Answer 1

if option.startswith('template'):
    hf = staticFile("static/{}/header".format(option))
    ...

Answer 2

使用 var 选项代替template-n：

hf = staticFile("static/" + option + "/header")
header = hf()
header = string.replace(header, "site_description", Settings.site_description)
fh = staticFile("static/" + option + "/header_forum")
...

如何缩短很多？
