Question

a)infile=open("c:\\temp.txt","r")
b)infile=open(file = "c:\\temp.txt","r+")
c)infile=open(file ="c:\\temp.txt","r+")

Answer 1

Answer:

infil =open("c:\\temp.txt,","r")

Answer 2

option 1 is correct answer

Explanation:

open(file, mode=’r’, buffering=-1, encoding=None, errors=None, newline=None)

* file – The file parameter specifies the relative path to the current working directory or absolute

• path of the file that you want to open and perform some operation. If file cannot be opened, an error occurs (OSError).

* mode – This is where you will specify the purpose of opening a file. For example, ‘r’ (the default)

• value opens a file in reading mode for text files. If you require writing to a text file, then use ‘w’ mode.

• For opening a file in write mode for appending text, use the ‘a’ value.
• The detailed list of modes is given in the last section.

Hence, option 1 is correct to open a file only in read only.
