Delete a Row/Column
At times, certain columns may not provide valuable information, making it advantageous to remove them. The pandas
library offers the drop()
function for this purpose. Let's delve into the function's syntax.
index
: Specifies the row indexes to be deleted (used whenaxis=0
);columns
: Identifies the column names to be deleted (used whenaxis=1
);axis
: Choose whether to remove labels from the rows (0) or columns (1). The default is 0.
In this section, we're going to work with a specific DataFrame. Let's examine it.
We notice that the continent
column contains numerous empty rows, making it less informative. Consequently, we'll remove it.
Time for some hands-on practice.
Tarefa
We have a DataFrame called audi_cars
. Take a close look at the provided dictionary and eliminate the irrelevant column. Give it a try!
