How to use column name In Python Pandas
We can use the first column name to get the first column.
Syntax:
dataframe.first_column
Example: Python code to get the first column using column name
Python3
# import pandas module import pandas as pd # create dataframe with 3 columns data = pd.DataFrame({ "id": [7058, 7059, 7072, 7054], "name": ['sravan', 'jyothika', 'harsha', 'ramya'], "subjects": ['java', 'python', 'html/php', 'php/js'] } ) # display dataframe print(data) print("--------------") # get first column by returning dataframe # using column_name print(data.id) |
Output:
We can also use the head() function within this to display the number of rows in the first column.
Example: Python code to get the first column using the column name
Python3
# import pandas module import pandas as pd # create dataframe with 3 columns data = pd.DataFrame({ "id": [7058, 7059, 7072, 7054], "name": ['sravan', 'jyothika', 'harsha', 'ramya'], "subjects": ['java', 'python', 'html/php', 'php/js'] } ) # display dataframe print(data) print("--------------") # get first column by returning dataframe # using column_name # display 1 row print(data.id.head(1)) print("--------------") # get first column by returning dataframe # using column_name # display 2 rows print(data.id.head(2)) print("--------------") # get first column by returning dataframe # using column_name # display 4 rows print(data.id.head(4)) |
