stat Module¶
The stat module provides constants and functions for interpreting file stat results from os.stat() and related functions.
Complexity Reference¶
| Operation | Time | Space | Notes |
|---|---|---|---|
| Mode check | O(1) | O(1) | Bitwise operation |
filemode() |
O(1) | O(1) | Convert mode to string |
File Mode Operations¶
Checking File Types¶
import os
import stat
# Get file stats - O(1)
file_stat = os.stat('myfile.txt')
# Check file type - O(1)
if stat.S_ISREG(file_stat.st_mode):
print("Regular file")
elif stat.S_ISDIR(file_stat.st_mode):
print("Directory")
elif stat.S_ISLNK(file_stat.st_mode):
print("Symbolic link")
# Convert to string - O(1)
mode_str = stat.filemode(file_stat.st_mode)
print(mode_str) # e.g., "-rw-r--r--"
Checking Permissions¶
import os
import stat
file_stat = os.stat('script.py')
# Check permissions - O(1)
if file_stat.st_mode & stat.S_IEXEC:
print("Executable")
if file_stat.st_mode & stat.S_IWRITE:
print("Writable")
