Selenium Python Automation Testing from Scratch and Frameworks - Writing Data Using Python

The video tutorial explains how to write code in Python to read from and write back to a text file. It introduces the 'with' statement for efficient file handling, eliminating the need for manual file closure. The tutorial demonstrates reading file content into a list, reversing the list, and writing the reversed content back to the file. It emphasizes the importance of file modes and provides a step-by-step guide to achieve the task, concluding with a code execution demonstration.

What is the advantage of using the 'with' statement in Python for file handling?

• It increases the speed of file operations.

• It allows multiple files to be opened simultaneously.

• It automatically closes the file after the block is executed.

• It provides a graphical interface for file handling.

Which mode should be used to open a file for reading in Python?

• x

• a

• r

• w

What does the 'readlines()' method do in Python?

• It writes a list of lines to a file.

• It reads all lines from a file into a list.

• It deletes all lines in a file.

• It appends lines to the end of a file.

How can you reverse a list in Python?

• Using the 'reverse()' method.

• Using the 'reversed()' function.

• Using the 'flip()' method.

• Using the 'invert()' function.

What is the purpose of reversing the list of lines read from a file?

• To sort the lines alphabetically.

• To write the lines back in reverse order.

• To remove duplicate lines.

• To convert the lines to uppercase.

Which method is used to write lines to a file in Python?

• write()

• insert()

• writelines()

• append()

What is the significance of specifying 'write mode' when opening a file?

• It allows writing to the file, overwriting existing content.

• It allows reading from the file.

• It prevents any modifications to the file.

• It creates a backup of the file before writing.

Why is it important to ensure correct indentation in Python code?

• It helps in debugging the code.

• It makes the code run faster.

• It is only important for aesthetic purposes.

• It is required for the code to execute correctly.

What happens if you do not specify a mode when opening a file in Python?

• The file cannot be opened.

• The file is opened in append mode by default.

• The file is opened in write mode by default.

• The file is opened in read mode by default.

What is the default mode when opening a file in Python if no mode is specified?

• Exclusive creation mode

• Read mode

• Write mode

• Append mode
