Python program to find tuples which have all elements divisible by K from a list of tuples

When it is required to find tuples that have all elements divisible by a specific value 'K', list comprehension along with the all() function can be used. The all() function returns True only when all elements in the tuple satisfy the divisibility condition.

Example

Let's find tuples where all elements are divisible by K ?

my_list = [(45, 90, 135), (71, 92, 26), (2, 67, 98)]

print("The list is:")
print(my_list)

K = 45
print("The value of K has been initialized to")
print(K)

my_result = [sub for sub in my_list if all(ele % K == 0 for ele in sub)]

print("Elements divisible by K are: " + str(my_result))

Output

The list is:
[(45, 90, 135), (71, 92, 26), (2, 67, 98)]
The value of K has been initialized to
45
Elements divisible by K are: [(45, 90, 135)]

How It Works

The solution uses list comprehension with nested logic:

• for sub in my_list − iterates through each tuple
• ele % K == 0 for ele in sub − checks if each element in the tuple is divisible by K
• all(...) − returns True only if all elements pass the divisibility test
• Only tuples where all elements are divisible by K are included in the result

Alternative Approach Using Filter

You can also use the filter() function for the same result ?

my_list = [(45, 90, 135), (71, 92, 26), (2, 67, 98)]
K = 45

result = list(filter(lambda sub: all(ele % K == 0 for ele in sub), my_list))
print("Elements divisible by K are:", result)

Elements divisible by K are: [(45, 90, 135)]

Conclusion

Use list comprehension with all() to filter tuples where every element is divisible by K. The all() function ensures that every element in the tuple meets the divisibility condition before including the tuple in the result.
