Consider the following Python statement:

Which of the following is an invalid statement in Python?
Consider the following Python statement:
F = open('CONTENT.TXT')
Which of the following is an invalid statement in Python?
Show Hint
F.seek(1, 0)
F.seek(0, 1)
F.seek(0, -1)
F.seek(0, 2)
The Correct Option is C
Solution and Explanation
Python's seek() method modifies a file's current position. It accepts two arguments: 1. offset: the byte position to move the file pointer. 2. whence: the reference point for offset. The valid values for whence are: 0 for the beginning of the file, 1 for the current file position, and 2 for the end of the file. An offset value of -1 for whence is invalid, thus F.seek(0, -1) is an incorrect usage.

- Write a user-defined function in Python named showInLines() which reads contents of a text file named STORY.TXT and displays every sentence in a separate line. Assume that a sentence ends with a full stop (.), a question mark (?), or an exclamation mark (!). Example:
If the content of the file STORY.TXT is:
Our parents told us that we must eat vegetables to be healthy. And it turns out, our parents were right! So, what else did our parents tell?
Then the function should display:
Our parents told us that we must eat vegetables to be healthy.
And it turns out, our parents were right!
So, what else did our parents tell?

Write a user-defined function in Python named showGrades(S) which takes the dictionary
Sas an argument. The dictionaryScontains Name: [Eng, Math, Science] as key:value pairs.
The function displays the corresponding grade obtained by the students according to the following grading rules:
\[ \begin{array}{|c|c|} \hline \textbf{Average of Eng, Math, Science} & \textbf{Grade} \\ \hline \geq 90 & A \\ \hline < 90 \text{ but } \geq 60 & B \\ \hline < 60 & C \\ \hline \end{array} \]
Example: Consider the following dictionary: \[ S = \{\text{"AMIT"}: [92, 86, 64], \text{"NAGMA"}: [65, 42, 43], \text{"DAVID"}: [92, 90, 88]\} \] The output should be: \[ \text{AMIT} - B \\ \text{NAGMA} - C \\ \text{DAVID} - A \]- CBSE Class XII - 2024
