Difference between Python Dictionary copy and = Operator

by suresh

In this section, we discuss the difference between Python Dictionary copy and = Operator with practical examples.

The Python Dictionary copy shallow copy the dictionary items to an entirely new dictionary. Whereas = operator creates an instance of the existing dictionary.

Difference between Python Dictionary copy and = Operator Example 1

In this example, we are showing how we can use these two options to copy the dictionary items to a new dictionary. As you can see, they both are giving the same result.

TIP: Please refer to the Dictionary to understand Python Dictionaries.

# Difference between Python Dictionary copy and = Operator

emp = {'name': 'John', 'age': 25 , 'job': 'HR', 'Sal': 725000}

print("Dictionary: ", emp)
print("Dictionary Length: ", len(emp))

newEmp = emp.copy()
print("\nDictionary: ", newEmp)
print("Dictionary Length: ", len(newEmp))

newEmp2 = emp
print("\nDictionary: ", newEmp2)
print("Dictionary Length: ", len(newEmp2))

OUTPUT

Difference between Python Dictionary copy and = Operator 1

Differentiate Dictionary copy and = Operator Example 2

In this program, we are using a dictionary clear function to remove the items from the dictionary. If you observe carefully, when we removed items from emp, newEmp2 is also returning an empty set.

# Difference between Python Dictionary copy and = Operator

emp = {'name': 'John', 'age': 25 , 'job': 'HR', 'Sal': 725000}

print("Dictionary: ", emp)
print("Dictionary Length: ", len(emp))

newEmp = emp.copy()
print("\nDictionary: ", newEmp)
print("Dictionary Length: ", len(newEmp))

newEmp2 = emp
print("\nDictionary: ", newEmp2)
print("Dictionary Length: ", len(newEmp2))

emp.clear()
print("\nDictionary: ", newEmp)
print("Dictionary Length: ", len(newEmp))

print("\nDictionary: ", newEmp2)
print("Dictionary Length: ", len(newEmp2))

OUTPUT

Difference between Python Dictionary copy and = Operator 2
