Subject: Computer Science

Fill in the Blanks:
1. The default file mode is _____________ mode.
2. A ________________ governs the type of operations (eg read/write/append) possible in
the opened file.
3. The two types of data files can be __________ files and ___________ files.
4. The other name for file object is _____________________.
5. The _____________ file mode will open a file for read and write purpose.
6. The _________ file mode will open a file for write and read purpose.
7. To close an open file, _______________method is used.
8. To read all file contents in the form of a list, _____________method is used.
9. To write a list in a file, _______________method may be used.
10. To force Python to write the contents of file buffer on to storage file, ________method
may be used.
11. . To read and write into binary files, _______________ module of Python is used.
12. The ____________ method of pickle module writes data into a binary file.
13. The _____________ method of pickle module reads data from a binary file.
14. The conversion of an object hierarchy in byte stream is called ___________ or
__________________.
15. The character that separates the values in csv files is called the ______________.
16. The default delimiter of csv files is _________________.
17. The csv files are actually _____________ files.
18. We can suppress EOL translation is text file by giving ______________ argument in
open().
19. The file mode to open a binary file for reading as well writing is ______________.
20. The file mode to open a text file for reading as well writing is ____________.
21. The file mode to open a text file for writing as well reading is ________________.
22. The file mode to open a binary file for writing as well as reading is ____________.
23. The file mode to open a csv file for reading as well as writing is ____________.
24. The file mode to open a csv file for appending as well as reading is _________.
25. To specify a different delimiter while writing into a csv file, ______________ argument is
used with csv.writer().
True/False
1. When you open a file for reading, if the file does not exist, an error occurs.
2. When you open a file for writing, if the file does not exist, an error occurs.
3. When you open a file for writing, if the file exists, the existing file is overwritten with the new
file.
4. The absolute paths are from the topmost level of the dictionary structure.
5. The relative paths are relative to the current working directory.
6. The relative path for a file always remains the same even after changing the directory.
7. The types of operations that can be carried out on a file depend upon the file mode a file is
opened in.
8. If no path is given with a file name in the file open(), then file must exist in the current directory.
9. Functions readline() and readlines() are essentially the same.
10. Python automatically flushes the file buffers before closing a file with close().
11. When you open a file for writing, if the file does not exist, a new file is created.
12. When you open a file for appending, if the file exists, the existing file is overwritten with the new
flile.
13. Conversion of an object hierarchy in byte stream is called Serialisation.
14. Serialisation process is also called pickling.
15. The load() of the pickle module performs pickling.
16. The dump() of the pickle module performs unpickling.
17. The csv files can only take comma as delimeter.
18. The csv files are text files.
