Here’s some output from a session I had with the Python interprester playing with a dict containing a nested list. Make sure you try things that you think shouldn’t work so that you understand the errors the Python interpreter will give back. Keep doing it until the answers you’re getting back from the interpreter are what you expect. Invoke the Python interpreter, and start working with lists, dicts, and nested variations. If you’re using Python for network automation, you’ll likely be using nested dicts and lists constantly.

COMPARE TWO LIST OF DICTIONARIES PYTHON HOW TO

Or you’ll assign the thing you need to a variable so that you only need to be clunky once.Įven so, understanding how to reference the data element you need is fundamental to maintaining your sanity when working in Python.

COMPARE TWO LIST OF DICTIONARIES PYTHON CODE

Your Python code isn’t likely to contain many clunky references like colorsList to get to the thing you need. One API I was recently working with returned a JSON object that the requests library converted into a dictionary containing a list containing more dictionaries. Simply add additional references to get down to the individual element you need to work with. Yes, Python will allow for more deeply nested data structures than I’ve shown you here. Will Python Allow For More Deeply Nested Data Structures? If colorsDict equals an entire list, how do we get at individual elements in the list? By adding an additional reference value. Python Dict Containing ListsĪ Python dictionary can contain a list as the value portion of a key-value pair entry. If colorsList is equal to the entire dict, how do we get at the individual values in the dict? By adding an additional reference value. Here’s a list containing a mix of string objects and dictionaries.

colorsDict = ‘Leafing Out Green’Ī Python list can contain a dictionary as a list item.

Use PEP8 guidelines and check your code for PEP8 compliance here. This is valid Python syntax as written below, but the dict could have also been written as one long line. tuple ( sorted ( ems () ) ) Share Improve this answer Follow edited at 15:44 answered at 22:03 S. Method 1: Use the comparison operators and Here is some very simple code using to compare the two dictionaries: The output is: If we slightly change. A set can be built only out of hashable items. Make this a tuple () and you have a hashable version of a dictionary. Lists are mutable and, thus, not hashable. The way weve been taught to compare two objects in Python is a bit misleading. The items () attribute is a list of tuples. It turns out comparing two lists in Python is just so tricky as comparing dict s. In this example, I split the key-value pairs across lines for readability. 3 Answers Sorted by: 5 You need a 'hashable' dictionary. A key is separated from its value by a colon. Python Tutorials: Difference between List & Array & Tuple & Set & Dict.

COMPARE TWO LIST OF DICTIONARIES PYTHON SERIES

The cmp() method compares the keys and values of the two dictionaries, and returns 0 if they are the same, -1 if the first dictionary is smaller, and 1 if the first dictionary is larger.ColorsList = Ī Python dictionary (aka dict) is a series of key-value pairs referenced by key name. The method takes two arguments: the first dictionary and the second dictionary. The cmp() method is used to compare two dictionaries in Python. Using the “cmp()” method to Python compare two dictionaries Since the keys and values of the two dictionaries are the same, the output of the code will be “The two dictionaries are equal”. We then compare the two dictionaries using the “=” operator.

In this example, we define two dictionaries dict1 and dict2.

Print("The two dictionaries are not equal") # Compare the two dictionaries using the "=" operator
