Question

Which of the following code snippets would create a new dataframe based upon a csv data file:

a) data = read_csv("file.txt")
b) data = load_csv("file.txt")
c) data = pd.read_csv("file.txt")
d) data = create_dataframe("file.txt")

Answer 1

code snippets would create a new dataframe based upon a csv data file is data = pd.read_csv("file.txt") (Option C)

Explanation:

The correct code snippet to create a new DataFrame based on a CSV data file is (c) data = pd.read_csv("file.txt"). In this code, the pd.read_csv() function is used from the pandas library to read the data from the specified CSV file ("file.txt") and create a DataFrame named 'data.' This function is specifically designed for reading CSV files and converting them into a tabular data structure, making it a suitable choice for this task.

The read_csv() function in pandas is versatile and allows you to customize the import process by specifying various parameters such as delimiter, header, and index column. It provides a convenient way to load CSV data into a DataFrame, which is a two-dimensional labeled data structure commonly used in data analysis and manipulation.

Contrastingly, options (a) data = read_csv("file.txt"), and (b) data = load_csv("file.txt") are incorrect. These options suggest the use of functions without specifying the pandas library (pd), and the correct syntax is to use pd.read_csv() for reading CSV files into a DataFrame in the pandas library. Option (d) data = create_dataframe("file.txt") is also incorrect, as there is no standard function in pandas named create_dataframe() for reading CSV files; the appropriate function for this purpose is pd.read_csv(). (Option C)

Answer 2

To create a new dataframe based on a CSV data file, the correct code snippet is C: data = pd.read_csv("file.txt").

Step-by-step explanation:

In Python, the pandas library is commonly used for working with data, including reading data from CSV files and creating dataframes. The correct code snippet is option C, data = pd.read_csv("file.txt"). This code uses the read_csv function from the pandas library to read the data from the CSV file "file.txt" and create a dataframe named "data."

The other options (A, B, and D) are incorrect. Option A uses read_csv but is missing the pd reference, which is necessary for using pandas functions. Option B and Option D contain functions (load_csv and create_dataframe) that are not valid functions in the pandas library for reading CSV files.

Option C) data = pd.read_csv("file.txt") is the answer.
