onerror provides an error handler if an error is encountered (optional).If this value is set to False, directories will be scanned from the bottom up (optional) topdown, when set to True, specifies that directories should be scanned from the top down.top is the top directory whose component file and folder names you want to retrieve (required).The os.walk() method accepts four parameters: Os.walk(top, topdown, onerror, followlinks) The syntax for the os.walk() method is as follows: ![]() Then, os.walk() returns the name of every file and folder within a directory and any of its subdirectories. The method iterates over each directory in a tree. The os.walk() function retrieves a list of files contained within a tree. The directory is called processed_data and is distinguishable from the other files because it does not have an extension. The /home/data_analysis/netflix directory contained six files and one directory. We print out the name of each file to the console using a Python print() statement. This loop iterates through every item in the list produced by os.listdir(). On the next line, we use the os.listdir() method to get a list of the files and folders in the /home/data_analysis/netflix directory. Then, we declare a Python variable called path, which stores the name of the path whose contents we want to retrieve. On the first line, we import the os module, which we need to do in order to access the os.listdir() function. Now, we can check to see if the file raw_data_2019.csv is in the folder. ![]() Get Your Coding Bootcamp Sponsored by Your Employer.Education Stipends for Coding Bootcamps.Best Coding Bootcamp Scholarships and Grants.Ultimate Guide to Coding Bootcamp Loans.What Is a Coding Bootcamp Job Guarantee?.Best Free Bootcamps and Coding Training. ![]() Best Online Coding Bootcamps and Courses.
