how to define a set in python code example

Example 1: empty set python

# Distinguish set and dictionary while creating empty set

# initialize a with {}
a = {}

# check data type of a
print(type(a))

# initialize a with set()
a = set()

# check data type of a
print(type(a))

Example 2: python set &

>>> A = {0, 2, 4, 6, 8};
>>> B = {1, 2, 3, 4, 5};

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

>>> print("Intersection :", A & B)
Intersection : {2, 4}

>>> print("Difference :", A - B)
Difference : {0, 8, 6}

# elements not present both sets
>>> print("Symmetric difference :", A ^ B)   
Symmetric difference : {0, 1, 3, 5, 6, 8}

Example 3: python set

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

print(set_example)

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

Example 4: set() python

#help set the array in python in order

Example 5: 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
