>>> B = {1, 2, 3, 4, 5};

>>> print("Union :", A | B)  
Union : {0, 1, 2, 3, 4, 5, 6, 8}

Difference : {0, 8, 6}

# elements not present both sets

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 in python

myNewSet = set()

myNewSet.add("what have you done")
myNewSet.add("to earn your place")
myNewSet.add("in this crowded world?")


"what have you done" in myNewSet		# ->	true
myNewSet.remove("to earn your place")
# ->	 myNewSet = {"what have you done", "in this crowded world?"}

python set

set_example = {1, 2, 3, 4, 5, 5, 5}

print(set_example)

# OUTPUT
# {1, 2, 3, 4, 5} ----- Does not print repetitions

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_Set = {1, 2, "hi", "test"}

for i in A_Set: #Loops through the set. You only get the value not the index
  print(i) #Prints the current value

python using set

list_1 = [1, 2, 1, 4, 6]

print(list(set(list_1)))

set() python

#help set the array in python in order

python set

my_set = set() # Use this to declare an empty set in python
my_set = {"apple", "orange"} # Use this to declare a set in python

python set

create set in python

# Different types of sets in Python
# set of integers
my_set = {1, 2, 3}
print(my_set)

# set of mixed datatypes
my_set = {1.0, "Hello", (1, 2, 3)}
print(my_set)

my_set = set()
// initialize empty set in python

#Definition: A collection of values (similiar spirit to python dictionary)
