遍历文件名列表以查看文件名是否在字典值(值是列表)中，然后打印键和文件名 [英] Iterate over list of file names to see if file name is in dictionary Values (Valuse are lists), then print Key and file name

问题描述

我仅限于使用python 2.7进行这项工作.

I'm limited to using python 2.7 for this work.

我想遍历file_list以查找哪些文件名包含任何dict值列表. 然后打印dict键和文件名.

I'd like to iterate over the file_list looking for which file names contain any of the dict values lists. Then print the dict key and the file name.

## dictionary derived from opening and reading csv file
name_dict = {'kat': ['1', '2', '4'], 'rod': ['3', '7', '9'], 'tim': ['5', '6', '8']} 

## list of files in a directory
file_list = ['1.pdf', '2.pdf', '3.pdf', '4.pdf', '5.pdf', '6.pdf', '7.pdf', '8.pdf', '9.pdf']

这是我自愿参加的一个项目，我对python很陌生. 字典key:values作为列表确实使我感到困惑.

This is for a project I volunteered for at work and I'm new-ish to python. It is the dictionary key:values as a list that is really confusing me.

非常感谢您的帮助:-)

Any help is much appreciated:-)

推荐答案

file_list = ['1.pdf', '2.pdf', '3.pdf', '4.pdf', '5.pdf', '6.pdf', '7.pdf', '8.pdf', '9.pdf']
name_dict = {'kat': ['1', '2', '4'], 'rod': ['3', '7', '9'], 'tim': ['5', '6', '8']}

for file in file_list:
    file_no_ext = '.'.join(file.split('.')[:-1])
    for key, value in name_dict.items():
        if file_no_ext in value:
            print(f'{file}: {key}')
            break

并输出:

1.pdf: kat
2.pdf: kat
3.pdf: rod
4.pdf: kat
5.pdf: tim
6.pdf: tim
7.pdf: rod
8.pdf: tim
9.pdf: rod
