Avoid using a bare except clause, as it can catch unexpected exceptions and make debugging difficult.
except clause can be used without specifying a particular exception. For example:
try:
# some code
except:
# handle any exception
However, it is a good practice to specify the exception type to make error handling more explicit and readable.

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.
Write a user-defined function in Python named showGrades(S) which takes the dictionary 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 ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
