Add list to dictionary Python | Example code

  • by

One way is to Add a list to the dictionary by Adding a nested list as a value using the append() method in Python. Create a new list and we can simply append that list to the value.

Example Add list to dictionary Python

Simple example code. The restriction with keys in the python dictionary is only immutable data types can be used as a key. So, we cannot use a dictionary of the list as a key. If we try to do this we will get a “TypeEerror”.

myDict = {"A": 0}

# Adding list as value
myDict["key1"] = [1, 2]

# A list
lst = ['X', 'Y']

# Adding this list as sublist in myDict 
myDict["key1"].append(lst)

print(myDict)
print(type(myDict))

Output:
