Python: Common tuples between two given lists

Python List: Exercise - 207 with Solution

Write a Python program to find the common tuples between two given lists.

Visual Presentation:

Python List: Common tuples between two given lists.

Sample Solution:

Python Code:

# Define a function 'test' that finds the common tuples between two lists of tuples.
def test(list1, list2):
    # Convert 'list1' and 'list2' into sets to remove duplicate tuples and make intersection easier.
    # Find the intersection (common tuples) between 'list1' and 'list2' using the 'intersection' method.
    result = set(list1).intersection(list2)
    # Convert the resulting set back to a list.
    return list(result)

# Define two lists of tuples 'list1' and 'list2'.
list1 = [('red', 'green'), ('black', 'white'), ('orange', 'pink')]
list2 = [('red', 'green'), ('orange', 'pink')]

# Print a message indicating the original lists.
print("\nOriginal lists:")
# Print the original lists 'list1' and 'list2'.
print(list1)
print(list2)

# Print a message indicating the purpose of the following lines of code.
print("\nCommon tuples between two said lists")
# Call the 'test' function to find the common tuples between 'list1' and 'list2' and print the result.
print(test(list1, list2))

# Define two different lists of tuples 'list1' and 'list2'.
list1 = [('red', 'green'), ('orange', 'pink')]
list2 = [('red', 'green'), ('black', 'white'), ('orange', 'pink')]

# Print a message indicating the original lists.
print("\nOriginal lists:")
# Print the original lists 'list1' and 'list2'.
print(list1)
print(list2)

# Print a message indicating the purpose of the following lines of code.
print("\nCommon tuples between two said lists")
# Call the 'test' function to find the common tuples between 'list1' and 'list2' and print the result.
print(test(list1, list2))

Sample Output:

Original lists:
[('red', 'green'), ('black', 'white'), ('orange', 'pink')]
[('red', 'green'), ('orange', 'pink')]

Common tuples between two said lists
[('orange', 'pink'), ('red', 'green')]

Original lists:
[('red', 'green'), ('orange', 'pink')]
[('red', 'green'), ('black', 'white'), ('orange', 'pink')]

Common tuples between two said lists
[('orange', 'pink'), ('red', 'green')]

Flowchart:

Flowchart: Common tuples between two given lists.

Python Code Editor:

Previous: Write a Python program to remove additional spaces in a given list.
Next: Sum a list of numbers. Write a Python program to sum the first number with the second and divide it by 2, then sum the second with the third and divide by 2, and so on.
