Appending multiple dictionaries to a list in Python can be a helpful operation when working with a large data set where dictionaries are used to contain data. This tutorial will guide you on appending multiple dictionaries to a list in Python.
Steps:
1. Create a list.
To append multiple dictionaries to a list you must first create an empty list to contain the dictionaries.
|
1 |
list_of_dicts = [] |
2. Create multiple dictionaries.
Before you can append dictionaries to a list, you must create the dictionaries.
|
1 2 |
dict1 = {"name": "Alice", "age": 22} dict2 = {"name": "Bob", "age": 25} |
3. Append dictionaries to the list.
To append dictionaries to a list, use the append() method. You can append a single dictionary at a time or multiple dictionaries at once using square brackets.
|
1 2 |
list_of_dicts.append(dict1) list_of_dicts.append(dict2) |
or
|
1 |
list_of_dicts += [dict1, dict2] |
4. Check the result.
To check the contents of the list, print the list.
|
1 |
print(list_of_dicts) |
[
{'name': 'Alice', 'age': 22},
{'name': 'Bob', 'age': 25}
]
Conclusion:
Appending multiple dictionaries to a list in Python is a simple process. By following these steps, you can easily append any number of dictionaries to a list. This operation is useful when you work with large data sets containing many dictionaries.
