In thisPart 3ofPython Data Structure series, we will be discussing what is a dictionary, how it differs from other data structure in python, how to create, delete dictionary objects and methods of dictionary objects. Dictionary is a built-in implementation of “Python Data Structure” which is...
Empty Dictionary: {} Dictionary after adding 3 elements: {0: 'Peter', 2: 'Joseph', 3: 'Ricky'} Dictionary after adding 3 elements: {0: 'Peter', 2: 'Joseph', 3: 'Ricky', 'Emp_ages': (20, 33, 24)} Updated key value: {0: 'Peter', 2: 'Joseph', 3: 'JavaTpoint', 'Emp...

Using update() Method: In this method, the item passed inside the update() method will be inserted into the dictionary. The item can be another dictionary or any iterable like a tuple of key-value pairs. Now, Let’s see how to add two new keys to the dictionary. Example person = {...
However, overall, the sched module still provides a clean way to get cron-like behavior.Working with delays can be frustrating if what you really want is for a task to execute at specific times. In addition to enter(), a sched instance also provides the enterabs() method with which you ...
