python - os.path.isfile isn't working as expected

Question

I am trying to check if a file exists in Python using os.path.isfile(), but it is returning false although the file does exist. For example, when I type /Users/jordanbaron/Desktop/hero-bg.jpg This is the output

Enter the directory to the ISO file (or just drag the file here): /Users/jordanbaron/Desktop/hero-bg.jpg 
/Users/jordanbaron/Desktop/hero-bg.jpg 
<type 'str'>
False

And the file DOES in fact exist.

Why is this happening?

filename = raw_input("Enter the directory to the ISO file (or just drag the file here): ")
print(filename)
print(type(filename))
print(os.path.isfile(filename))

Answer 1

Your code, as posted, works:

File exists

/usr/bin/python2.7 /home/surest/github/tests/test.py
Enter the directory to the ISO file (or just drag the file here): /home/surest/Desktop/duties.odt
/home/surest/Desktop/duties.odt
<type 'str'>
True


Process finished with exit code 0

Typo in filename/path

 /usr/bin/python2.7 /home/surest/github/tests/test.py
Enter the directory to the ISO file (or just drag the file here): /home/surest/Desktop/meesa-typoed.odt
/home/surest/Desktop/meesa-typoed.odt
<type 'str'>
False

Process finished with exit code 0
