是否可以用字典缩短我的项目代码，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pre-根据给定的命令行参数编号在各自的路径中定义文件。我想知道是否可以将这些文件添加到字典中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':

使用选项var值代替template-n：

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