python中如何挂载自己写的在子目录下的模块？

Question

main.py

layout_format = {}

for filename in os.listdir('mod'):
    if filename.endswith('py'):
        for line in open(os.path.join('mod',filename)):
            eval(line)
print(layout_format)
exit()

mod/md.py

markdown_template = "# %(title)s\r\nAuthor: %(author)s\r\nCreate Date: %(created_time)s\r\nLast Update: %(updated_time)s\r\n\r\n%(content)s\r\n"


def markdown(self):
    return markdown_template % self


layout_format['md'] = markdown

然而执行出错。。。我想问下，一般python中怎么挂载自己写的子模块呢？

Answer 1

layout_format = {} for filename in os.listdir('mod'): if filename.endswith('py'): exec(open(os.path.join('mod',filename)).read()) print(layout_format) exit() 原来这样就可以了。。。。JavaScript的eval!=python的eval，对应的是exec

Answer 2

import sys,os sys.path.append(os.path.abspath('.'))
