python 之 从文件夹中批量删除指定文件

耗费将近一天，主要是对python不熟悉，写的乱七八糟。

最终虽然实现了，但是极度智障的程序，记录一下，等待技术见长，回看再修改吧~~~~~~~

import glob
import os

#generate text file of nii data 
def GenerateText(path_gen):
    all_path_gen = []
    for roots, dirname, files in os.walk(path_gen):
        all_path_gen.append(roots)
        #print(all_path)
        writeText = open('F:/mat/Nii.txt', 'w')    
        for path in all_path_gen:
            folders = glob.glob(path + os.sep + '/*.nii.gz')
            #print(folders)
            if len(folders) <= 0: #when the path is empty ,continue run the program
                continue
            writeText.write(os.sep + folders[0] + ', ' + '\n')
            writeText.write(os.sep + folders[1] + ', ' + '\n')
            writeText.write(os.sep + folders[2] + ', ' + '\n')
            writeText.write(os.sep + folders[3] + ', ' + '\n')
            writeText.write(os.sep + folders[4] + ', ' + '\n')
        writeText.close()

#delete files that name in text file named Nii 
def DeleteFiles(path_del, txt_file):
   all_path_del = []
   file_path = []
   with open('F:/mat/Nii.txt', 'r') as nii:
       for roots, dirname, files in os.walk(path_del):
           all_path_del.append(roots)
           for path in all_path_del:
               files = glob.glob(path + os.sep + '/*.nii.gz')
               if len(files) <= 0:
                   continue
               for file in files:
                    os.remove(file)
#这一块怎么都实现不了，一次只能匹配一个文件删除一个文件，气的我直接用os.remove删掉了。
#不知道txt文件生成的意义~呼~勉强看吧，继续课题了~以后再战

#                    for lines in nii:                                       
#                        if file in lines:
#                            print(file)
#                            os.remove(file)
#                    else:
#                        print(file)
#                        os.remove(file)
# =============================================================================
