• os.X_OK Value to include in the mode parameter of access() to determine if path can be executed.
Return Value
This method returns True if access is allowed, False if not.
Example
The following example shows the usage of access() method.
#!/usr/bin/python
import os, sys
# Assuming /tmp/foo.txt exists and has read/write permissions.
ret = os.access("/tmp/foo.txt", os.F_OK)
print "F_OK - return value %s"% ret
ret = os.access("/tmp/foo.txt", os.R_OK)
print "R_OK - return value %s"% ret
ret = os.access("/tmp/foo.txt", os.W_OK)
print "W_OK - return value %s"% ret
ret = os.access("/tmp/foo.txt", os.X_OK)
print "X_OK - return value %s"% ret
Let us compile and run the above program, this will produce the following result:
F_OK - return value True
R_OK - return value True
W_OK - return value True
X_OK - return value False
