Python Delete/Remove a File If Exists On Disk

How can I check if a file exists in a directory with Python and then delete/remove it using python program?

You can easily check if a file exists, in a current directory using the following python syntax:

os.path.isfile(filename)

Next, you can use the following syntax to delete the file:

os.remove(filename)

Check If a File Exists and Then Delete It in Python

#!/usr/bin/python
import os
 
## get input ##
filename=raw_input("Type file name to remove: ")
 
## delete only if file exists ##
if os.path.exists(filename):
    os.remove(filename)
else:
    print("Sorry, I can not remove %s file." % filename)

Sample outputs:

A Better Option To Delete A File In Python

The following code gives an error information when it can not delete the given file name:

#!/usr/bin/python
import os
 
## get input ##
filename=raw_input("Type file name to remove: ")
 
## check if a file exists on disk ##
## if exists, delete it else show message on screen ##
if os.path.exists(filename):
	try:
		os.remove(filename)
	except OSError, e:
		print ("Error: %s - %s." % (e.filename,e.strerror))
else:  
	print("Sorry, I can not find %s file." % filename)

Sample outputs:
