我正在尝试解压 python 中的文件。我给我的程序一个文件路径，文件的主目录有9个子目录，python循环遍历它们，查找具有特定名称的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文件号和解压缩文件，其中包含某些名称。< / p>
我已经编写了一些代码但发生了什么没有，没有错误，没有任何警告：
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：即使我打印出来的内容也没有出现，可能是什么原因？
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
＆＃34; /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/tarfile.py" ;,第1672行，公开 引发ReadError（＆＃34;文件无法成功打开＆＃34;） tarfile.ReadError：无法成功打开文件
这是我的修改后的代码：
导入操作系统 import os.path import 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()
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!!
答案 0 :(得分：1)
for i in range(1,1):什么也没做。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
我想你想要更像这样的东西：
编辑： 我已经修复并测试了以下内容。
<强> 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):将为您提供子目录编号1 - 9.
{:0>2}将取i和0的值取为2位数。删除了%并使用了较新的format string syntax。
修复了for root, dir, files in os.walk(p):行的标签，以便每次p更新时都会执行。
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的测试失败了。
为path=p添加了tar.extractall()参数，以确保将tar文件解压缩到找到它的同一文件夹中。如果不是所需的行为，您可以删除它。
