Passing data between separately running Python scripts

Question

If I have a python script running (with full Tkinter GUI and everything) and I want to pass the live data it is gathering (stored internally in arrays and such) to another p

Answer 1

You could use the pickling module to pass data between two python programs.

import pickle 

def storeData(): 
    # initializing data to be stored in db 
    employee1 = {'key' : 'Engineer', 'name' : 'Harrison', 
    'age' : 21, 'pay' : 40000} 
    employee2 = {'key' : 'LeadDeveloper', 'name' : 'Jack', 
    'age' : 50, 'pay' : 50000} 

    # database 
    db = {} 
    db['employee1'] = employee1 
    db['employee2'] = employee2 

    # Its important to use binary mode 
    dbfile = open('examplePickle', 'ab') 

    # source, destination 
    pickle.dump(db, dbfile)                   
    dbfile.close() 

def loadData(): 
    # for reading also binary mode is important 
    dbfile = open('examplePickle', 'rb')      
    db = pickle.load(dbfile) 
    for keys in db: 
        print(keys, '=>', db[keys]) 
    dbfile.close()
