How do you print rows and columns in python?
Hello, readers! In this article, we will be focusing on different ways to print column names in Python. So, let us get started! We often come across questions and problem statements wherein we feel the need to deal with data in an excel or
csv file i.e. in the form of rows and columns. Python, as a programming language, provides us with a data structure called ‘DataFrame’ to deal with rows and columns. A Python DataFrame consists of rows and columns and the Pandas module offers us various functions to manipulate and deal with the data occupied within these rows and columns. Today, we will be having a look at the various different ways through which we can fetch and display the column header/names of a dataframe or a csv file. We would be referring the below csv
file in the below examples– 1. Using pandas.dataframe.columns to print column names in PythonWe can use Example: import pandas file = pandas.read_csv("D:/Edwisor_Project - Loan_Defaulter/bank-loan.csv") for col in file.columns: print(col) In this example, we have loaded the csv file into the environment. Further, we have printed the column names through a for loop using dataframe.columns variable. Output: age ed employ address income debtinc creddebt othdebt default 2. Using pandas.dataframe.columns.valuesPython provides us with Syntax: Example: import pandas file = pandas.read_csv("D:/Edwisor_Project - Loan_Defaulter/bank-loan.csv") print(file.columns.values) So, the data.columns.values gives us a list of column names/headers present in the dataframe. Output: ['age' 'ed' 'employ' 'address' 'income' 'debtinc' 'creddebt' 'othdebt' 'default'] 3. Python sorted() method to get the column namesPython Have a look at the below syntax! Syntax: Example: import pandas file = pandas.read_csv("D:/Edwisor_Project - Loan_Defaulter/bank-loan.csv") print(sorted(file)) Output: ['address', 'age', 'creddebt', 'debtinc', 'default', 'ed', 'employ', 'income', 'othdebt'] ConclusionBy this, we have come to the end of this topic. Hope this article turns out to be a hack for you in terms of different solutions for a single problem statement.

We can perform basic operations on rows/columns like selecting, deleting, adding, and renaming. In this article, we are using Dealing with ColumnsIn order to deal with columns, we perform basic operations on columns like selecting, deleting, adding and renaming. Column Selection:
Output: For more examples refer to How to select multiple columns in a pandas dataframe Column Addition: In Order to add a column in Pandas DataFrame, we can declare a new list as a column and add to a existing Dataframe.
Output: For more examples refer to Adding new column to existing DataFrame in Pandas Column Deletion: In Order to delete a column in Pandas DataFrame, we can use the drop() method. Columns is deleted by dropping columns with column names.
Output: Data Frame after Dropping Columns- For more examples refer to Delete columns from DataFrame using Pandas.drop() Dealing with Rows:In order to deal with rows, we can perform basic operations on rows like selecting, deleting, adding and renaming. Row Selection:
Output: For more examples refer to Pandas Extracting rows using .loc[] Row Addition: In Order to add a Row in Pandas DataFrame, we can concat the old dataframe with new one.
Output: Data Frame after Adding Row- For more examples refer to Add a row at top in pandas DataFrame Row Deletion: In Order to delete a row in Pandas DataFrame, we can use the drop() method. Rows is deleted by dropping Rows by index label.
Output: Data Frame after Dropping values- For more examples refer to Delete rows from DataFrame using Pandas.drop() Problem related to Columns:
