Simple example code change the global dictionary value in the function. That’s easy to Modify a global dictionary in python within a function.<\/p>\n\n\n\n

Note<\/strong>: To assign to a global variable from a function you need to use a global directive. Otherwise, Python will create a local variable with the same name instead.<\/p>\n\n\n\n

dic1 = {'a': 1, 'b': 2}\n\n\ndef func():\n    global dic1\n    dic1['a'] = 100\n\n\nprint(dic1)\nfunc()\nprint('New Dictionary ', dic1)\n<\/code><\/pre>\n\n\n\n
