Question

What is the output for the given python code?

fp = open("sample2.txt", "w")
print(fp.tell())
fp.write('12345678')
print(fp.tell())
fp.close()

a)
0
8
b)
0

c)
1
8
d)
1
7

Correct answer is option 'A'. Can you explain this answer?

Answer

The correct answer is option A.

Concept:
The given python code is,
tell() method:
This function returns an integer that specifies the current position of the file object in the file. The position so specified is the byte position from the beginning of the file till the current position of the file object.
The syntax of using tell() is:
file_object.tell()
The given code is,
fp = open("sample2.txt", "w")
print(fp.tell())
fp.write('12345678')
print(fp.tell())
fp.close()

Explanation:
The given sample2.txt opens the file in write mode. If the file already exists, all the contents will be overwritten. If the file doesn’t exist, then a new file will be created.
Here is the file newly created and write the contents. And we will notice the position of the handle before writing and after writing to the Sample2.txt file.
the position of the handle before writing=0
after writing to the Sample2.txt file = 8
Hence the correct answer is
0
8

Answer

Explanation:

Opening a file in write mode:
- The code opens a file named 'sample2.txt' in write mode using the `open()` function with mode 'w'.
- The `fp` variable now points to the file object.

Getting the current position in the file:
- The `tell()` method returns the current position in the file. Initially, the file pointer is at the beginning of the file.
- When `print(fp.tell())` is executed, it prints 0 as the initial position in the file.

Writing to the file:
- The code attempts to write the integer value 12345678 to the file using the `write()` method.
- Since `write()` method expects a string, the code will raise a TypeError.

Getting the current position in the file after writing:
- Before the TypeError is raised, the `print(fp.tell())` statement is executed to print the position in the file.
- Since the write operation failed, the file position remains unchanged at 0.

Closing the file:
- The file is closed using the `close()` method to release system resources associated with the file.

Final Output:
- The final output of the code will be:
- Initial position in the file: 0 (Before writing)
- Final position in the file: 0 (After writing)
