如何在python中使用一个循环压缩多个文件?
我试过了,但它给了我一个错误:
from zipfile_infolist import print_info
import zipfile
import fileinput
import glob
import os
for name in glob.glob( '*.xlsx' ):
zf = zipfile.ZipFile('%(name)s.zip', mode='w')
try:
zf.write('%(name)s')
finally:
print 'closing'
zf.close()
print
print_info('%(name)s')
这是追溯:
Traceback (most recent call last):
File "C:/Users/Fatt-DELL-3/ser.py", line 10, in <module>
zf.write('%(name)s')
File "C:\Program Files\IBM\SPSS\Statistics\22\Python\lib\zipfile.py", line 1031, in write
st = os.stat(filename)
WindowsError: [Error 2] The system can not find the file specified: '%(name)s'
答案 0 :(得分:2)
如果您查看Python's string formatting documentation,只要您的字符串包含mapping
之类的内容,就会使用'%(name)s
类型的操作。为此,您需要使用像dict这样的映射对象来跟踪它,例如:
'%(name)s' % {'name':name}
您需要将此添加到您放置'%(name)s'
的每个位置所以这些行:
zf = zipfile.ZipFile('%(name)s.zip', mode='w')
zf.write('%(name)s')
print_info('%(name)s')
应写成:
zf = zipfile.ZipFile('%(name)s.zip' % {'name':name}, mode='w')
zf.write('%(name)s' % {'name':name})
print_info('%(name)s' % {'name':name})
