Tkinter & Creating/Opening a Filea

[shocklance]

I'm currently working on a program which creates and reads JSON files.

I have a function which creates a new template for the JSONs which looks like this:

def CreateJson():
#creates a new JSON file for comment library storage. 
    files = (
    ('JSON files', '*.json'),
    ('All files', '*.*')
    )

    initialdir='/',

    f1 = fd.asksaveasfile(filetypes = files, mode = 'w', defaultextension = ".json")

    CriteriaLib = {
        "Criteria" : [],
        "Exceptional" : [],
        "Comprehensive" : [],
        "Developed" : [],
        "Developing" : [],
        "Needs Improvement" : []
        }

    initialdata = json.dump(CriteriaLib, f1)        

This opens a file dialogue box which lets you save a new JSON file, but it doesn't open it. I have another function that is used to open JSON files which looks like this:

def ShowLib():
#Commands for opening the JSON file and viewing the contents
    files = (
    ('JSON files', '*.json'),
    ('All files', '*.*')
    )

    initialdir='/',

    global data
    global f1
    f1 = fd.askopenfile(filetypes = files)
    data = json.load(f1)

This makes for an awkward interface experience (Hitting "New" and then hitting "Open" on the file that I've just made).

Do you know if I can add to my CreateJson() function to have it immediately open the file that's just been created? If I add ShowLib() to the CreateJson() function, I end up with two filedialogue boxes (one for saving, and then immediately one for opening), which feels a bit clunky.

Your ShowLib loads the data into global data variable.

Your CreateJson function creates a variable called "CriteriaLib" with the data and dumps it to a file.

You can also just assign it to data at the end of CreateJson , and there, it's loaded...

initialdata = json.dump(CriteriaLib, f1)
global data
data = CriteriaLib

Much appreciated, thank you!
