![]() ![]() popitem() Returns the last inserted key and value as a tuple. get() Returns the value of the specified key. values() Returns all the dictionary's values. keys() Returns all the dictionary's keys. Return the result list after all the dictionaries in the list have been checked. Remove all the items from the dictionary. You can use dict() function along with the zip() function, to combine separate lists of keys and values obtained dynamically at runtime.If the key is present, append the corresponding value to the result list.Check if the given key is present in the dictionary using the in operator.Therefore, only one element is left with the same value on the key.values() returns a. Iterate over each dictionary in the list using a for loop. Each new element with the same email overwrites any existing ones.Initialize an empty list result that will store the values corresponding to the given key.Define a function named get_values that takes two arguments – a list lst and a string key.Method 6: Using a for loop and checking each dictionary in the list for the given key. To get keys from a dictionary by value, use list comprehension and the items() method. Additionally, the function uses recursion, which creates a new stack frame for each call, resulting in O(n) space complexity. This is because the function creates a result list that is as long as the input list. Additionally, the function has to access the value of the key in each dictionary, which takes O(m) time on average.Īuxiliary Space: O(n), where n is the length of the list. In the worst case, the function has to check every dictionary in the list for the key, resulting in O(n) time complexity. Time Complexity: O(n*m), where n is the length of the list and m is the average number of keys in each dictionary.

We have added names (keys) using the syntax namevalue, so meow is given the name cat, woof. Commonly Asked Data Structure Interview Questions Dictionaries (or dict in Python) are a way of storing elements just like you would in a Python list. The three items in the list are meow, woof and neigh. ![]() Check if the present key value equals the minimum value.
