Let’s dive in! Method 1: Using a Simple Loop One of the most straightforward ways to find a key by its value in a Python dictionary is to use a simple loop. This method involves iterating through the dictionary items, checking each value against the target value, and returning the ...
Shallow Copy of Python Dictionary The problem with dict() and copy() is they only apply shallow copy to the object being used; this will be a problem if your dictionary has a complex nested structure. Shallow copying will only copy the first layer in the memory that it sees because nested...
Python dictionariesare a built-indata typefor storingkey-value pairs. The dictionary elements are mutable and don't allow duplicates. Adding a new element appends it to the end, and in Python 3.7+, the elements are ordered. Depending on the desired result and given data, there are various ...

The json.load(file) function creates and returns a new Python dictionary with the key-value pairs in the JSON file. Then, this dictionary is assigned to the data variable, and the result is displayed. You can also check the type of the variable using the built-intype()function of Python...
Python allows a nested function to access the outer scope of the enclosing function. This is a critical concept in decorators, known as a closure. A closure in Python is a function that remembers the environment in which it was created, even after that environment is no longer active. This...
From Python version 3.9 onward, we can use the merge operators (represented by|) to combine two dictionaries: >>>x = a | b>>>print(x) {1:'fish',2:'chips',3:'jelly',4:'time'} The dictionary merge operators can also be used in the place of nested dictionaries too. Here, the ...
