Final answer:
To view a small sample of data from the end of a series or data frame in programming, use the tail() function from a library like pandas, specifying the number of rows to display with an optional parameter.
Step-by-step explanation:
The question pertains to viewing a small sample of data from the end of a series or data frame. In the context of programming, particularly in data analysis with languages like Python using libraries such as pandas, this is accomplished by using specific methods or functions. For example, in the pandas library, the tail() function is utilized to view the last few rows of a DataFrame or Series. To use the tail() function, you would call it on your DataFrame or Series object, optionally specifying the number of rows you wish to view. Here is a step-by-step explanation using a pandas DataFrame as an example:
- Import the pandas library: import pandas as pd
- Create or load your DataFrame: df = pd.DataFrame(data)
- Use the tail method: df.tail(n) where n is the number of rows you want to display from the end.
This will output the last n rows of the DataFrame, providing a snapshot of the end of your data set.
