Test: File Handling in Python - CUET Humanities MCQ

The file is a named location on a secondary storage media where data are permanently stored for later access.

The readline([n]) method reads one complete line from a file where each line terminates with a newline (\n) character.

The Python considers everything as an object.

De-serialization or Unpickling is the inverse of pickling process where a byte stream is converted back to Python object.

The valid file access modes for opening a file in C language are r, w and a.
You can open the file to be able to read and write as follows:
f = open(my_file, 'r+')
f = open(my_file, 'w+')
f = open(my_file, 'a+')
However, there is no s file access mode in C language.

The file access mode "r+" is used to open existing file for both reading and writing.

File access modes for reading and writing the binary file are "rb" and "wb", respectively.

Serialization process is also called pickling.

Python makes sure that any unwritten or unsaved data is flushed off (written) to the file before it is closed.

The tell() method returns an integer that specifies the current position of the file object in the file.
