File Handling in Python and OCR

This video tutorial by Craig covers basic file handling operations in Python, focusing on reading and writing data to text files. It explains the importance of data dependency and the steps involved in file operations, including opening, reading, writing, and closing files. The tutorial also highlights differences in syntax when using the OCR Exam Reference Language compared to Python.

What is the primary purpose of the program discussed in the introduction?

• To manage a database

• To read and display character attributes from a text file

• To perform mathematical calculations

• To create a graphical game

What is the significance of data dependency in the program?

• It allows the program to run faster

• It reduces the size of the text file

• It ensures the data is read in the correct order

• It makes the program more secure

Which command is used to open a file for reading in Python?

• open(file, 'w')

• open(file, 'x')

• open(file, 'r')

• open(file, 'a')

What does the strip() function do when reading a line from a text file?

• Converts text to uppercase

• Removes leading and trailing whitespace

• Adds a new line character

• Encrypts the text

What is the purpose of setting a Boolean variable to false when reading a file?

• To count the number of lines

• To store the file size

• To track if the end of the file has been reached

• To indicate the file is open

What does the 'A' parameter signify when opening a file in Python?

• Create a new file

• Read the file

• Overwrite the file

• Append to the end of the file

Which operation is performed by the command F.write()?

• Opens the file

• Closes the file

• Writes a line to the file

• Reads a line from the file

What is the final step after writing data to a file?

• Close the file

• Delete the file

• Encrypt the file

• Reopen the file

How does the OCR Exam Reference Language differ from Python in file handling?

• It uses different file extensions

• It is slower than Python

• It cannot handle text files

• It does not require specifying read/write mode

In the OCR Exam Reference Language, how is a file opened?

• Using open(file, mode)

• Using open(file)

• Using open(file, 'w')

• Using open(file, 'r')
