We can choose or change a particular array within a Pandas DataFrame by using the column labels.
To select a particular array, we can use the square bracket notation and pass the label of the column we want to select as an argument. For example, to select the 'name' column from a DataFrame called 'df', we can use the following code:
name_array = df['name']
To change the values in a particular array, we can also use the square bracket notation and assign new values to the array. For example, to change the values in the 'name' column of the 'df' DataFrame, we can use the following code:
df['name'] = ['Alice', 'Bob', 'Charlie', 'David']
This will replace the current values in the 'name' column with the new values specified in the list.
