Let’s add the contents of CSV file as a list of tuples. ] Reading csv into list of tuples using Python : # Print the list of lists with the header To include the header row, we can first read the other rows like the previous example and then add the header to the list. Using Pandas to read csv into a list of lists with header : # for creating a list of lists from Dataframe rows We have to read the CSV into a dataframe excluding the header and create a list of lists.ĭfObj = pd.read_csv('data.csv', delimiter=',') We can also select particular rows and columns from the CSV file by using Pandas. Selecting specific value in csv by specific row and column number : #The reader object is passed into the list( ) to generate a list of lists #The object having the file is passed into the reader #Opening the csv file as a list of lists in read mode Then passing the reader object into the list() will return a list of lists. Importing csv to a list of lists using csv.reader :ĬSV.reader is a python built-in function from the CSV module which will help us read the CSV file into the python. We will be using pandas module for importing CSV contents to the list without headers.ĬSV File name – data.csv Id,Name,Course,City,Sessionģ2,Veena,DSA,New York,Night Read a CSV into list of lists in python :ġ. In this article, we will demonstrate how we can import a CSV into a list, list of lists or a list of tuples in python. Save my name, email, and website in this browser for the next time I comment.Read CSV into a list of lists or tuples or dictionaries | Import csv to list in Python. Your email address will not be published. That’s all about how to convert CSV to dictionary in Python. We can also use the csv.reader class for this, but we have to perform some complex operations to convert this data to a dictionary and append them to a list. The csv.DictReader can parse the csv to dictionaries which can be appended to a list. The same pandas.to_dict() method can be used for this but we specify the format of the final dictionary as records. We also discussed how to convert CSV to list of dictionaries. We also used the numpy.loadtxt() method for the same. The pandas module provides a direct method to read CSV and convert it into a dictionary with the to_dict() function. We could also use the filter() function with this method. The csv module was used to parse the CSV data and convert it to a dictionary. We discussed the basic structure of both these objects and how the final format may be different in different ways. We discussed different methods to convert CSV to dictionary in Python. It combines the elements and we convert this to a dictionary with the dict() function.The zip() method combines two iterable objects to return a zip-type object.We store the first row in a variable using the next() function.We parse the CSV data using the csv.reader class.Every key is unique in a dictionary and can be used to access its corresponding value. It can store elements in the form of key-value pairs. The pandas and csv module are used commonly to parse CSV data in Python.Ī dictionary is an important data structure in Python. In Python, we can read CSV files easily using different functions. It is very commonly used to transfer records and is compatible with Excel as well to store data in rows and columns.
