Answer» Correct choice is (b) It is used for object deserialization The best I can explain: We have been working with simple textual data. What if we are working with objects rather than simple text? For such situations, we can use the pickle module. This module serializes Python objects. The Python objects are converted into byte streams and written to text files. This process is called pickling. The inverse operation, reading from a file and reconstructing objects is called deserializing or unpickling.

Answer» The correct answer is (a) fileObject.readlines( sizehint ); The best I can explain: The method readlines() reads until EOF using readline() and returns a list containing the lines. If the optional sizehint argument is present, instead of reading up to EOF, whole lines totalling approximately sizehint bytes (possibly after rounding up to an internal buffer size) are read. Syntax Following is the syntax for readlines() method: fileObject.readlines( sizehint ); Parameters sizehint — This is the number of bytes to be read from the file.

Answer» Correct option is (b) file object = open(file_name [, access_mode][, buffering]) To explain I would say: Open() function correct syntax with the parameter details as shown below: file object = open(file_name [, access_mode][, buffering]) Here is parameters’ detail: file_name: The file_name argument is a string value that contains the name of the file that you want to access. access_mode: The access_mode determines the mode in which the file has to be opened, i.e., read, write, append, etc. A complete list of possible values is given below in the table. This is optional parameter and the default file access mode is read (r). buffering: If the buffering value is set to 0, no buffering will take place. If the buffering value is 1, line buffering will be performed while accessing a file. If you specify the buffering value as an integer greater than 1, then buffering action will be performed with the indicated buffer size. If negative, the buffer size is the system default(default behavior).
