Sometimes, we want to make a copy of dicts on assignment with Python.
In this article, we’ll look at how to make a copy of dicts on assignment with Python.
How to make a copy of dicts on assignment with Python?
To make a copy of dicts on assignment with Python, we can call the copy method.
For instance, we write:
a = {'foo': 2}
b = a.copy()
b['bar'] = 3
print(a)
print(b)
We call a.copy to make a copy of a and assign it to b.
Then we added a new entry with key 'bar' to b.
Since we made a copy of a and assigned that to b, a is unchanged when we changed b.
So a is {'foo': 2} and b is {'foo': 2, 'bar': 3}.
Conclusion
To make a copy of dicts on assignment with Python, we can call the copy method.
