Set method in python

Python set

# A set contains unique elements of which the order is not important
s = set()
s.add(1)
s.add(2)
s.remove(1)
print(s)
# Can also be created from a list (or some other data structures)
num_list = [1,2,3]
set_from_list = set(num_list)

Set method in python

# Creating an empty set
b = set()
print(type(b))

## Adding values to an empty set
b.add(4)
b.add(4)
b.add(5)
b.add(5) # Adding a value repeatedly does not changes a set
b.add((4, 5, 6))

## Accessing Elements
# b.add({4:5}) # Cannot add list or dictionary to sets
print(b)

## Length of the Set
print(len(b)) # Prints the length of this set

## Removal of an Item
b.remove(5) # Removes 5 fromt set b
# b.remove(15) # throws an error while trying to remove 15 (which is not present in the set)
print(b)

print(b.pop())
print(b)

Set in python

a = {1, 3, 4, 5, 1}
print(type(a))
print(a)

b = {1, 2, 6, 7, 2, 2, 2}
print(type(b))
print(b)
