Consider the following Python statement:
F = open('CONTENT.TXT')
Which of the following is an invalid statement in Python?
F.seek(1, 0)
F.seek(0, 1)
F.seek(0, -1)
F.seek(0, 2)
The seek() method in Python is used to change the file’s current position.
It takes two arguments:
1. offset: The position (in bytes) to move the file pointer to.
2. whence: The reference point for offset.
Valid values for whence are:
0: Beginning of the file.
1: Current file position.
2: End of the file.
A value of -1 for whence is invalid, making F.seek(0, -1) incorrect.
event = "G20 Presidency@2023" L = event.split(' ') print(L[::-2])
S
as an argument.
The dictionary S
contains 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:
\[
\text{AMIT} - B \\
\text{NAGMA} - C \\
\text{DAVID} - A
\]
A tuple named subject stores the names of different subjects. Write the Python commands to convert the given tuple to a list and thereafter delete the last element of the list.
a = 20 def convert(a): b = 20 a = a + b convert(10) print(a)Select the correct output from the given options:
