Printing rows of the Data
By default, data_frame.head() displays the first five rows and data_frame.tail() displays last five rows. If we want to get first ‘n’ number of rows then we use, data_frame.head(n) similar is the syntax to print the last n rows of the data frame.
Python3
#displaying first five rows display(data_frame.head()) #displaying last five rows display(data_frame.tail()) |
