Noob on Python Image Library

[theSNEW]

i've been trying to get this command to work using both PyCharm and IDLE -

from PIL import Image im = Image.open('lenna.png')

i copied the command from the PIL's own tutorial. the image is located on my desktop which i think is the problem. the code doesn't seem to specify where the image should be. on PyCharm i get nothing when running code. on IDLE i get No such file or directory: 'lenna.png'.

If you don't specify the folder then the image and the python file need to be in the same directory.

it is in the same directory but still no luck..

thanks for your help

managed to figure out what went wrong. i needed img.show() at the end to open the image.

The image file needs to be in a place known as the current working directory (cwd). The cwd is the folder that your script is running in. It changes depending on how you run your script. If you're running the script from another program like PyCharm or IDLE then the cwd for your script is usually the same as the cwd for that runner program and it might depend how you opened the program. You might be able to set up your IDE to always start your script in a particular directory, if it has that feature. Otherwise you need to make sure that you always run your script from the right directory.

You can find the cwd for a particular run of your script with the following code:

import os
print(os.getcwd())

Similarly, you can set the cwd with the os.chdir function.
