🌟 Student Marks Retrieval Program

This is a simple Python program that stores marks of students in a dictionary and allows the user to retrieve them by entering the student’s name.

📌 Features

• Stores student marks in a dictionary.
• Asks the user if they want to retrieve marks.
• Retrieves and displays the marks when the student’s name is entered.
• Handles invalid inputs and errors gracefully.

📝 Code Explanation

1. A dictionary named dict is defined with student names as keys and their marks as values.

2. The user is asked whether they want to retrieve marks (yes/no).

3. If the answer is yes:

   • The program asks for the student’s name.
   • The first letter of the input is capitalized to match dictionary keys.
   • The marks are displayed if the name exists in the dictionary.

4. If the answer is no, it prints "Okay".

5. If the user enters something else, it prints "Answer in yes or no only!".

6. A try-except block ensures that errors (like wrong names) are caught and displayed with their exception type.

▶️ Example Run

Want to retrieve Marks of any student? (yes/no) yes
Enter the student's name : lakshya
Lakshya's marks is 21

Want to retrieve Marks of any student? (yes/no) no
Okay

Want to retrieve Marks of any student? (yes/no) yes
Enter the student's name : Rahul
Error: KeyError

🌟 List Slicing and Reversing Example

This Python program demonstrates how to extract a portion of a list and then reverse it using built-in Python functions.

---

📌 Features

• Creates a list of numbers from 1 to 10.
• Extracts the first 5 elements from the list using slicing.
• Reverses the extracted elements using Python’s reversed() function.
• Displays the original list, the extracted part, and the reversed extracted list.

---

📝 Code Explanation

lakshya = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]  # Original list
first = lakshya[0: 5]                      # Extract first 5 elements
reversed = list(reversed(first))           # Reverse the extracted list

print(f"Original list: {lakshya}")
print(f"Extracted first 5 elements: {first}")
print(f"Reversed extracted elements: {reversed}")

---

▶️ Sample Output

Original list: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Extracted first 5 elements: [1, 2, 3, 4, 5]
Reversed extracted elements: [5, 4, 3, 2, 1]

---

📚 Concepts Used

• List Slicing → list[start:end] extracts elements within a range.
• Reversing → reversed() is a built-in function to reverse sequences.
• Type Conversion → list() is used to convert the reversed object back to a list.

🚀 How to Run

1. Save the code in a file (e.g., list_reverse.py).

2. Run in terminal:

   python list_reverse.py
