Python Program to Iterate Set Items

Write a Python program to Iterate Set Items. The for loop is the most common one to iterate over set items. In this example, we used for loop to iterate both the numeric and string set.

# Itearte Over Sets

set1 = {10, 20, 30, 40, 50, 60}

print("The Total Items in this Set = ")
for val in set1:
    print(val, end = ' ')


set2 = set("Tutorial Gateway")

print("The Total Items in this Set = ")
for char in set2:
    print(char, end = ' ')

Python Program to Iterate Set Items

Here, we converted the set to lists and used the for loop range to iterate and print set items based on the index.

# Itearte Over Sets

set1 = {11, 33, 55, 77, 99, 111}

list1 = list(set1)

print("The Total Items in this Set = ")
for i in range(len(list1)):
    print(list1[i], end = ' ')


set2 = set("TutorialGateway")
list2 = list(set2)

print("\n\nThe Total Items in this Set = ")
for i in range(len(list2)):
    print(list2[i], end = ' ')

Iterating set items using for loop output

The Total Items in this Set = 
33 99 55 11 77 111 

The Total Items in this Set = 
l r G w u i y o t a e T

This program uses the enumerate to iterate the set items. Generally, we don’t need the id. So you can use the for _, value in enumerate(setName).

# Itearte Over Sets

set1 = {11, 33, 55, 77, 99, 111}

print("The Total Items in this Set = ")
for i, value in enumerate(set1):
    print(i, value)

set2 = set("Python")

print("\nThe Total Items in this Set = ")
for i, value in enumerate(set2):
     print(i, value)


print("\nThe Total Items in this Set = ")
for _, value in enumerate(set1):
    print(value, end = '  ')

print("\nThe Total Items in this Set = ")
for _, value in enumerate(set2):
     print(value, end = '  ')

Iterating set values enumerate output

The Total Items in this Set = 
0 33
1 99
2 55
3 11
4 77
5 111

The Total Items in this Set = 
0 y
1 o
2 n
3 t
4 P
5 h

The Total Items in this Set = 
33  99  55  11  77  111  
The Total Items in this Set = 
y  o  n  t  P  h

It is another Python example of iterating over Python sets using a list and list comprehension. In this example, to act, we use a Python list and Python list comprehension.

# Itearte Over Sets

set1 = {5, 10, 20, 25, 30, 35, 40}

print("The Total Items in this Set = ")
x = [print(val, end = ' ') for val in set1]

set2 = set("Python")

print("The Total Items in this Set = ")
x = list(val for val in set2)
print(x)
print(*x)

Iterating set items using list comprehension output

The Total Items in this Set = 
35 20 5 40 25 10 30 

The Total Items in this Set = 
['h', 'P', 'y', 'o', 't', 'n']
h P y o t n

Use iter() to iterate over set elements

In the program below, we use the built-in iter() function that returns an iterator. Next, a for loop iterates over that iterable to print the set elements.

s = {10, True, "Hi", 20.52, 50}

for i in iter(s):
    print(i)

True
Live
Hi
50
20.52
10

Use enumerate() to iterate over set elements

This program uses the enumerate() function to print set elements along with index position.

s = {10, 25, 50, 75, 100}

for i, val in enumerate(s):
    print(f"index: {i} and Value: {val}")

index: 0 and Value: 50
index: 1 and Value: 100
index: 2 and Value: 25
index: 3 and Value: 10
index: 4 and Value: 75
