使用python的Untar文件没有错误/警告？
使用python的Untar文件没有错误/警告？
提问于 2015-10-27 00:47:43
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和文件的主目录，它有9个子目录，python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，然后我遍历目录中的01-09文件号，然后解压缩文件中的特定名称。
我已经编写了一些代码，但是所发生的是nothing，没有错误，没有警告--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:即使我打印出来的东西也没有出现，原因是什么？
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，在打开ReadError(“文件无法成功打开”)中，tarfile.ReadError:无法成功打开文件
这是我的数字化代码：
导入os导入os.path导入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:该文件是一个tgz文件！！

for i in range(1,1):什么也不做。你不会得到任何迭代。
试试看：
>>> 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。
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):将给出子目录号1-9.
{:0>2}将把i和0的值取为2位数.删除%并使用更新的格式字符串语法。
修正了for root, dir, files in os.walk(p):行的选项卡，这样每次p更新时它都会执行。
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。
将path=p参数添加到tar.extractall()中，以确保将tar文件解压缩到找到它的文件夹中。如果这不是所需的行为，您可以删除它。
执行之前的untarscript.py:
