In Build Function

add(x)

• Adds item x to the set

Example

s={10,20,30}
s.add(40)
print(s)

Output

{40, 10, 20, 30}

update(x,y,z)

• To add multiple items to the set.
• Arguments are not individual elements and these are Iterable objects like List, range etc.
• All elements present in the given Iterable objects will be added to the set.

Example

s={10,20,30}
l=[40,50,60,10]
s.update(l,range(5))
print(s)

Output

{0, 1, 2, 3, 4, 40, 10, 50, 20, 60, 30}

Question

What is the difference between add() and update() functions in set?

Answer

• We can use add() to add individual item to the Set, where as we can use update() function to add multiple items to Set.
• add() function can take only one argument where as update() function can take any number of arguments but all arguments should be iterable objects.

copy()

• Returns copy of the set.
• It is cloned object.

Example

s={10,20,30}
s1=s.copy()
print(s1)

Output

{10, 20, 30}

pop()

• It removes and returns some random element from the set.

Example

s={40,10,30,20}
print(s)
print(s.pop())
print(s)

Output

{40, 10, 20, 30}
40
{10, 20, 30}

remove(x)

• It removes specified element from the set.
• If the specified element not present in the set then we will get KeyError.

Example

s={40,10,30,20}
s.remove(30)
print(s)
s.remove(50)

Output

{40, 10, 20}
KeyError: 50

discard(x)

• It removes the specified element from the set.
• If the specified element not present in the set then we won’t get any error.

Example

s={10,20,30}
s.discard(10)
print(s)
s.discard(50)
print(s)

Output

{20, 30}
{20, 30}

Questions

• What is the difference between remove() and discard() functions in set?
• Explain differences between pop(),remove() and discard() functions in set?

clear()

• To remove all elements from the set.

Example

s={10,20,30}
print(s)
s.clear()
print(s)

Output

{10, 20, 30}
set()
