[3 marks]Explain the difference between '/' and '//' operators in Python.
[3 marks]Explain the difference between '/' and '//' operators in Python.
[3 marks]Differentiate between compiler and interpreter.
[3 marks]Explain the concept of key-value pairs in a dictionary.
[3 marks]Create a dictionary of 3 students with their marks and write code to find the highest marks.
[5 marks]Write a program to count vowels in a given string.
[5 marks]Write a program to find the largest number in a list without using the max() function.
[5 marks]Create a dictionary of 3 students with their marks and write code to find the highest marks.
[5 marks]Write a script that takes a list of numbers and returns a new list with only even numbers.
[5 marks]Write a program to check if a number is prime.
[5 marks]Find the error: x = 10 if x = 10: print('Yes')
[3 marks]Explanation:Assignment operator '=' is used instead of comparison operator '=='.
Predict the output: s = 'Python' print(s[::-1])
[3 marks]Explanation:The slice [::-1] reverses the string.
Predict the output: lst = [1, 2, 3] lst.append([4, 5]) print(len(lst))
[3 marks]Explanation:The list [4, 5] is appended as a single element, so the list becomes [1, 2, 3, [4, 5]].
Predict the output: lst = [1, 2, 3] lst.append([4, 5]) print(len(lst))
[3 marks]Explanation:The list [4, 5] is appended as a single element, so the list becomes [1, 2, 3, [4, 5]].
Predict the output: print(2 ** 3 ** 2)
[2 marks]Explanation:Exponentiation is evaluated right-to-left. 3**2 is 9, and 2**9 is 512.
Predict the output: s = 'Python' print(s[::-1])
[2 marks]Explanation:The slice [::-1] reverses the string.
Predict the output: s = 'Python' print(s[::-1])
[2 marks]Explanation:The slice [::-1] reverses the string.
Predict the output: lst = [1, 2, 3] lst.append([4, 5]) print(len(lst))
[2 marks]Explanation:The list [4, 5] is appended as a single element, so the list becomes [1, 2, 3, [4, 5]].
