For that we will select the column by number or position in the dataframe using iloc[] and it will return us the column contents as a Series object. Syntax: data.columns.values Example: import pandas file = pandas.read_csv("D:/Edwisor_Project - Loan_Defaulter/bank-loan.csv") print(file.columns.values) That is, when we use print we will print column names (i.e., the labels). This calls format which formats the data frame column-by-column, then converts to a character matrix and dispatches to the print method for matrices.. Output: Here’s how you go about labelling them as you like. Please use ide.geeksforgeeks.org, isnull () That is, we will get the column names by the following code as well. Select columns with spaces in the name, Use columns that have the same names as dataframe methods (such as ‘type’), Pick columns that aren’t strings, and; Select multiple columns. Here’s the result of the above code: In the next example, we are going to use the keys() method to print all the names in the dataframe: Second, we can get the exact same result by using the keys() method. In this tutorial we will be looking on how to get the list of column names in the dataframe with an example. In this post, we will use Pandas read_csv to import data from a CSV file (from this URL). data.frame.. Say that you created a DataFrame in Python, but accidentally assigned the wrong column name.
