How To Create File With Open Function In Python?

In Linux environment, I want to create a file and write text into it: HTMLFILE: '$MYUSER/OUTPUT/myfolder/mytext.html' f = open(HTMLFILE, 'w') IOError: [Errno 2] No such file or di

Solution 1:

os.path.expandvars() can help:

f = open(os.path.expandvars(HTMLFILE), 'w')

open only deals with actual file names. expandvars can expand environment variables in strings.

Solution 2:

There are two ways. Using os.environ() to get variable value

HTML_PATH = "/OUTPUT/myfolder/mytext.html"f = open(os.environ('MYUSER') + HTMLFILE, 'w')

and using os.path.expandvars():

HTMLFILE = "$MYUSER/OUTPUT/myfolder/mytext.html"f = open(os.path.expandvars(HTMLFILE), 'w')

Solution 3:

$MYUSER refers to a shell variable. Python does not resolve those. Use the os package to get the users home directory through os.getenv('MYUSER')
