In this article, we are going to learn how to convert the list of tuples into a dictionary. Converting a list of tuples into a dictionary is a straightforward thing.
Follow the below steps to complete the code.
- Initialize the list with tuples.
- Use the dict to convert given list of tuples into a dictionary.
- Print the resultant dictionary.
Example
Let's see the code.
# initializing the list
tuples = [('Key 1', 1), ('Key 2', 2), ('Key 3', 3), ('Key 4', 4), ('Key 5', 5)]
# converting to dict
result = dict(tuples)
# printing the result
print(result)If you run the above code, you will get the following result.
Output
{'Key 1': 1, 'Key 2': 2, 'Key 3': 3, 'Key 4': 4, 'Key 5': 5}
Let's add value as list in the resultant dictionary using setdefault() method.
Follow the below steps to complete the code.
- Initialize the list with tuples.
- Iterate over the list of tuples.
- Set default value for the key and append the value.
- Print the result.
Example
Let's see the code.
# initializing the list
tuples = [('Key 1', 1), ('Key 2', 2), ('Key 3', 3), ('Key 4', 4), ('Key 5', 5)]
# result
result = {}
# iterating over the tuples lists
for (key, value) in tuples:
# setting the default value as list([])
# appending the current value
result.setdefault(key, []).append(value)
# printing the list
print(result)If you run the above code, you will get the following result.
Output
{'Key 1': [1], 'Key 2': [2], 'Key 3': [3], 'Key 4': [4], 'Key 5': [5]}
