Python: Get last modified information of a file
Python Datetime: Exercise-38 with Solution
Write a Python program to get last modified information of a file.
Sample Solution:
Python Code:
import os, time
def last_modified_fileinfo(filepath):
filestat = os.stat(filepath)
date = time.localtime((filestat.st_mtime))
# Extract year, month and day from the date
year = date[0]
month = date[1]
day = date[2]
# Extract hour, minute, second
hour = date[3]
minute = date[4]
second = date[5]
# Year
strYear = str(year)[0:]
# Month
if (month <=9):
strMonth = '0' + str(month)
else:
strMonth = str(month)
# Date
if (day <=9):
strDay = '0' + str(day)
else:
strDay = str(day)
return (strYear+"-"+strMonth+"-"+strDay+" "+str(hour)+":"+str(minute)+":"+str(second))
print()
print(last_modified_fileinfo('test.txt'))
print()
Sample Output:
2017-04-19 15:15:52

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
