使用python解压文件没有错误/警告？答案

【问题标题】：Untar file using python no error/warnings?使用python解压文件没有错误/警告？
【发布时间】：2015-10-27 00:47:43
【问题描述】：

我正在尝试解压缩 python 中的文件。我给我的程序一个文件路径，该文件的主目录有 9 个子目录，python 循环遍历它们，找到具有特定名称的 tar 文件并解压缩它们。

所以我的output_text 文件有我的主目录，然后我循环遍历该目录中的01-09 文件编号和解压缩 具有特定名称的文件。

我已经写了一些代码，但是发生了什么什么都没有，没有错误，没有警告什么都没有：

def main():
    output_path = "/Users/rs/Documents/clients_file.txt"
    path = []
    with open(output_path) as f:
        for exptini_path_raw in f:
            exptini_path = exptini_path_raw.strip()
            path.append(exptini_path)

for i in range(1,1):
    for j in range(0,len(path)):
        if i < 10:
            p = "/%s/0%d/middleware"%(path[j],i)
        else:
            p = "/%s/%d/middleware"%(path[j],i)
    for root, _, files in os.walk(p):
            for f in files:
                if not 'client-logs' or 'middleware-logs' in f:
                    continue
                print 'going to extract %s'%f
                f1 = os.path.join(p,f)
                tar = tarfile.open(f1)
                tar.extractall()
                tar.close()



if __name__ == '__main__':
    main()

注意：连我打印出来的都没有出现，请问是什么原因？

编辑：我修改了我的代码，现在得到了这个

File "unzip_files.py", line 47, in <module>
    main()
  File "unzip_files.py", line 40, in main
    tar = tarfile.open(f1)
  File

“/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/tarfile.py”，第 1672 行，打开 raise ReadError("文件无法成功打开") tarfile.ReadError: 文件无法成功打开

这是我修改后的代码：

导入操作系统导入 os.path 导入tar文件

def main():
    output_path = "/Users/rs/Documents/clients_file.txt"
    path = []
    with open(output_path) as f:
        for exptini_path_raw in f:
            exptini_path = exptini_path_raw.strip()
            path.append(exptini_path)
            print path

for i in range(1,10):
    print i
    for j in range(0,len(path)):
        print j
        if i < 10:
            p = "/%s/0%d"%(path[j],i)
        else:
            p = "/%s/%d"%(path[j],i)
        print p
        for root, _, files in os.walk(p):
            for f in files:
                if not 'client-logs' or 'middleware-logs' in f:
                    continue
                print 'going to extract %s'%f
                f1 = os.path.join(p,f)
                tar = tarfile.open(f1)
                tar.extractall()
                tar.close()



if __name__ == '__main__':
    main()

注意：该文件是 tgz 文件！！

标签： python tar

【解决方案1】：

for i in range(1,1): 什么都不做。你不会得到任何迭代。

试一试：

>>> for i in range(1,1):
...     print i
... 
>>> for i in range(1,2):
...     print i
... 
1

我想你想要更多这样的东西：

编辑： 我已经修复并测试了以下内容。

untarscript.py

import os, tarfile

def main():
    output_path = "/Users/rs/Documents/clients_file.txt"
    path = []
    with open(output_path) as f:
        for exptini_path_raw in f:
            exptini_path = exptini_path_raw.strip()
            print "Adding to path: {}".format(exptini_path)
            path.append(exptini_path)

    for i in range(1,10):
        for j in range(0,len(path)):
            p = "{}/{:0>2}/middleware".format(path[j], i)
            print "Path to search for tar files: {}".format(p)
            for root, dirs, files in os.walk(p):
                for f in files:
                    print "Investigating file: {}".format(f)
                    if not ('client-logs' in f or 'middleware-logs' in f):
                        print "This file does not match expected file name...skipping: {}".format(f)
                        continue
                    print 'going to extract {} to folder {}'.format(os.path.join(p,f), p)
                    f1 = os.path.join(p,f)
                    tar = tarfile.open(f1)
                    tar.extractall(path=p)
                    tar.close()

if __name__ == '__main__':
    main()

for i in range(1,10): 将为您提供子目录号 1 - 9。

{:0>2} 将 i 的值和 0 填充为 2 位数字。删除了% 并使用了更新的format string syntax。

修复了 for root, dir, files in os.walk(p): 行的制表符，以便每次更新 p 时都会执行。

将if not 'client-logs' or 'middleware-logs' in f: 替换为if not ('client-logs' in f or 'middleware-logs' in f):，因为middleware-logs 的测试失败。

为tar.extractall() 添加了path=p 参数，以确保将tar 文件解压缩到找到它的同一文件夹中。如果它不是所需的行为，您可以删除它。
