Now we will define a basic check whether either file does exist using theis_file()method. We will define the next block to check whether a file is empty using thegetsize()function from theosmodule. frompathlibi
os.path.isfile() By usingos.path.isfile(path)we can check if ourpathis a regular file. It will follow symbolic links, so it will return true if the link points to a file. The syntax ofisfile()is the same asexists()and accepts thepathas a parameter. You will need to import the...
# (2) If no file name is specified, this procedure can be skipped. # File information of the system software on the file server. The file name extension is '.cc'. REMOTE_IMAGE = { 'product-name': { 'S16700' : { 'path': '/image/software_file_name.cc', 'sha256': '', }, ...
Again, just likeisfile,os.path.isdirdoes follow symlinks. It is also just a simple wrapper aroundos.statandstat.S_ISDIR(mode), so you're not getting much more than convenience from it. Checking if Either Exist Another way to check if a path exists (as long as you don't care if the...

If any tests fail, you can re-run the failing test(s) in verbose mode. For example, iftest_osandtest_gdbfailed, you can run: make test TESTOPTS="-v test_os test_gdb" If the failure persists and appears to be a problem with Python rather than your environment, you canfile a bug...
