Sorting dict items¶ Let us understand how we can sort the dict items in Python. dict is nothing but group of key value pairs where keys are unique. sorted on dict returns only sorted keys. In [7]: famous_players = { ‘Pete Sampras’: ‘Tennis’, ‘Sachin Tendulkar’: ‘Cricket’, ‘Brian Lara’: ‘Cricket’, ‘Diego Maradona’: ‘Soccer’, ‘Roger Federer’: ‘Tennis’, ‘Ian …
Process dict values¶ Let us understand how we can process the values in dicts. We have already seen a function called as values which return all the values as a list like object. In [1]: order_item_subtotals = { 1: 299.98, 2: 199.99, 3: 250.0, 4: 129.99 } In [2]: order_item_subtotals Out[2]: {1: 299.98, 2: 199.99, 3: 250.0, …
List of dicts¶ Let us see an example of how we can read data from a file into list of dicts using Python as programming language.* When we read data from a file into a list, typically each element in the list will be of type binary or string. We can convert the element into …
List of tuples¶ Let us see an example of how we can read data from a file into list of tuples using Python as programming language.* When we read data from a file into a list, typically each element in the list will be of type binary or string. We can convert the element into …
Common Examples – dict¶ Let us see some common examples while creating dict in Python. If you are familiar with JSON, dict is similar to JSON.* A dict can have key value pairs where key is of any type and value is of any type. However, typically we use attribute names as keys for dict. …
Manipulating dict¶ Let us understand how we can manipulate the dicts in Python.* We can add new key value pairs to dict by using typical assignment. We can also use assignment operation to update existing key value pair in the dict. setdefault can be used to get the element from the dict by using key. …
