Question

Consider the statement given below:

f1 = open(“pqr.dat”,“______”)

Which of the following is the correct file mode to open the file in read only mode?

पर्याय

• a

• rb

• r+

• rb+

Answer 1

rb

Explanation:

1. File Type: The extension .dat Usually indicates a binary file.
2. Read-Only Mode: In Python, the character 'r' is used for reading. Adding ‘b’ specifies that the file should be opened in binary mode.
3. Why others are wrong:
   • ‘a’ is for appending data.
   • ‘r+’ allows both reading and writing.
   • ‘rb+’ allows reading and writing in binary format.
