csv (comma-separated values) files are a popular format for storing tabular data. in python, the csv module provides functionalities to read and write csv files easily. in this tutorial, we will explore how to read data from a csv file and store it in a python array using the csv module.
step 1: import the csv module
to begin, import the csv module in your python script or jupyter notebook.
step 2: open the csv file
use the open() function to open the csv file in read mode. specify the file path and use the newline='' parameter to ensure consistent behavior across different platforms.
step 3: create a csv reader object
create a csv reader object using the csv.reader class. pass the opened file object to it.

now, iterate through the csv rows and store them in a python array.
step 5: print or use the array
you can print the array or use the data for further processing as needed.
