dealing with list of dictionaries python

Step # 1: Create a list of nested dictionaries. Pandas_dataframe = pd.DataFrame(student_data)Īge city name # After transposing, inner keys become column names By using key:value pair format the key is generated.

# Note, this only works if your nested dictionaries are set up in a In python, the list of dictionaries is the feature to store and retrieve the datas with the list concept. In my experiments, this is faster than using pd.concat (especially when the number of 'sub-dataframes' is large) at the cost of being more verbose.Ĭonvert list of nested dictionary into pandas dataframeĭataframe = pd.DataFrame(nested_dictionary) Pd.om_items(list(om_iterable(d.iteritems() for d in my_list))).T Putting these into a dataframe using data = pd.DataFrame(my_list) returns something unusable, as each cell has information on a, b, c and d in it. So each key in the main dictionaries has 3 values. Finally, we use the DataFrames function in the pandas library to create a Data Frame. Although we do not intend to cover all of them, the following sections will give us a glimpse of what we can accomplish by using these data structures in this series. We then create another for loop to add lines to a new list that was initially empty. With these concepts in mind, let's review some of the available properties and methods of lists and dictionaries in Python. In this article, we will see how we can convert a given Python list, whose elements are a nested dictionary, to a Pandas Datframe.įirst, we take a list of nested dictionaries and extract rows of data from it. But for applying computations or parsing using such packages like pandas, we need to convert this data to data frames.

Often Python will receive data from various sources, which can be in different formats like csv, JSON, etc., which can be converted to Python list or dictionaries, etc.

Let’s walk through the step-by-step procedure for creating a Pandas Dataframe using a list of nested dictionaries. Given a list of nested dictionaries, we will write a Python program to create a Pandas dataframe using it.
