Explain discard and remove method with example. (4 marks)12. Write down the symbol of Bitwise OR, Intersection method and Bitwise XOR

1. Discard and Remove Method in Python (2 marks):

Both discard() and remove() functions in Python are used to remove elements from a set. The difference between the two lies in their behavior when the element to be removed does not exist in the set.

• Discard Method: The discard() function leaves a set unchanged if the element is not found in the set. For example:

s = {1, 2, 3, 4, 5}
s.discard(3)  # s becomes {1, 2, 4, 5}
s.discard(6)  # s remains {1, 2, 4, 5} as 6 is not in the set

• Remove Method: The remove() function raises a KeyError if the element is not found in the set. For example:

s = {1, 2, 3, 4, 5}
s.remove(3)  # s becomes {1, 2, 4, 5}
s.remove(6)  # This will raise a KeyError as 6 is not in the set

2. Symbols of Bitwise OR, Intersection Method and Bitwise XOR (2 marks):

• Bitwise OR: The symbol for Bitwise OR is '|'. It performs a logical OR operation on each bit of its two operands. If either bit is 1, the corresponding result bit is set to 1. Otherwise, the result bit is set to 0.

• Intersection Method: The symbol for Intersection is '&'. In the context of sets in Python, the intersection method returns a set that contains the similarity between two or more sets.

• Bitwise XOR: The symbol for Bitwise XOR is '^'. It performs a logical exclusive OR operation on each bit of its two operands. If both bits are the same, the corresponding result bit is set to 0. Otherwise, the result bit is set to 1.
