I'm trying to unzip a file, and read one of the extracted files, and delete the extracted files.

1. Files extracted (e.g. we got file1 and file2)
2. Read file1, and close it.

```
with open(file1, 'r') as f:
    data = f.readline()
f.close()

```
3. Do something with the "data".
4. Remove the files extracted. 

```
os.remove(file1)

```

Everything went fine, except it received these messages at the end. The files were also removed. How do I close the files properly?

```
    /tmp/file1: No such file or directory
    140347508795048:error:02001002:system library:fopen:No such file or directory:bss_file.c:398:fopen('/tmp/file1','r')
    140347508795048:error:20074002:BIO routines:FILE_CTRL:system lib:bss_file.c:400:

```

**UPDATE:**
(My script looks similar to these)

```
#!/usr/bin/python
import subprocess, os

infile = "filename.enc"
outfile = "filename.dec"
opensslCmd = "openssl enc -a -d -aes-256-cbc -in %s -out %s" % (infile, outfile)   
subprocess.Popen(opensslCmd, shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE,      close_fds=True)
os.remove(infile)

```
