5. File to List

Write a Python program to read a file line by line and store it into a list.

Sample Solution:-

Python Code:

def file_read(fname):
        with open(fname) as f:
                #Content_list is the list that contains the read lines.     
                content_list = f.readlines()
                print(content_list)

file_read(\'test.txt\')

Sample Output:

['Welcome to w3resource.com.\n', 'Append this text.Append this text.Append this text.\n', 'Append this text.\n
', 'Append this text.\n', 'Append this text.\n', 'Append this text.\n']
