How To Create An Empty Dictionary In Python

Estimated reading time: 1 minute

In our recent video Python dictionary interview questions, we discussed a number of topics around Python dictionaries .

Here we will discuss how to create an empty dictionary.

In the below code, you will see there are two ways to create:

  1. Use a variable that is equal to empty curly brackets
  2. Just make an empty variable equal to the dict() function.

Creating empty dictionaries has many benefits as you can manipulate them as they are mutable.

Also, they can grow and shrink as you need, you just need to make sure that any new key you add is unique and not already stored in the dictionary.

Another thing to note about them is that they are unordered.

Finally, if you are adding data to a dictionary, the keys are case-sensitive, so the same key can exist in the dictionary, but it has to be different regards the case applied to it.

# How do you create an empty dictionary?
empty_dict1 = {}
empty_dict2 = dict()
print(empty_dict1)
print(empty_dict2)
print(type(empty_dict1))
print(type(empty_dict2))

Output:
{}
{}
<class 'dict'>
<class 'dict'>
