python - How to insert strings and slashes in a path? -

i'm trying extract tar.gz files situated in diffent files named srm01, srm02 , srm03. file's name must in input (a string) run code. i'm trying :

import tarfile import glob  thirdbloc = 'srm01' #then, must 'srm02', or 'srm03' f in glob.glob('c://users//asediri//downloads/srm/'+thirdbloc+'/'+'*.tar.gz'):     tar = tarfile.open(f)     tar.extractall('c://users//asediri//downloads/srm/'+thirdbloc) 

i have error message:

ioerror: crc check failed 0x182518 != 0x7a1780e1l 

i want first sure code find .tar.gz files. tried print paths after glob:

thirdbloc = 'srm01' #then, must 'srm02', or 'srm03' f in glob.glob('c://users//asediri//downloads/srm/'+thirdbloc+'/'+'*.tar.gz'):     print f 

that gives :

c://users//asediri//downloads/srm/srm01\20160707000001-server.log.1.tar.gz c://users//asediri//downloads/srm/srm01\20160707003501-server.log.1.tar.gz 

the os.path.exists method tell me files doesn't exist.

print os.path.exists('c://users//asediri//downloads/srm/srm01\20160707000001-server.log.1.tar.gz') 

that gives : false

any way todo work ? what's best way have first of right paths ?

in order join paths have use os.path.join follow:

import os  import tarfile import glob  thirdbloc = 'srm01' #then, must 'srm02', or 'srm03' f in glob.glob(os.path.join('c://users//asediri//downloads/srm/', thirdbloc, '*.tar.gz'):     tar = tarfile.open(f)     tar.extractall(os.path.join('c://users//asediri//downloads/srm/', thirdbloc))
