Updating/running code when path changes

[hermannhaf]

You need a periodic event. In tkinter you could use .after() to call a function.

def update_phase():
    with open('number.json', 'r') as f:
        distros_dict = json.load(f)
    for distro in distros_dict:
        op = json.dumps(distro["text"])
    str = path+op+".png"
    # Open file and update image

    # Repeat in an hour 3,600,000 milliseconds
    root.after(3600000, update_phase)

Thanks. But I now get this error:

Error:
AttributeError: type object 'str' has no attribute 'read'

I'm trying to figure out what it means.
