77. Transform Dictionary into List of Tuples

Write a Python program to transform a dictionary into a list of tuples.

• Use dict.items() and list() to get a list of tuples from the given dictionary.

Sample Solution:

Python Code:

# Define a function 'test' that takes a dictionary 'd' and converts it into a list of tuples using the 'items' method.
def test(d):
    # Use the 'items' method to convert the dictionary into a list of key-value pairs (tuples).
    return list(d.items())

# Create a dictionary 'd' with key-value pairs.
d = {'Red': 1, 'Green': 3, 'White': 5, 'Black': 2, 'Pink': 4}

# Print the original dictionary.
print("Original Dictionary:")
print(d)

# Call the 'test' function to convert the dictionary 'd' into a list of tuples (key-value pairs).
print("\nConvert the said dictionary to a list of tuples:")
print(test(d))

Sample Output:

Original Dictionary:
{'Red': 1, 'Green': 3, 'White': 5, 'Black': 2, 'Pink': 4}

Convert the said dictionary to a list of tuples:
[('Red', 1), ('Green', 3), ('White', 5), ('Black', 2), ('Pink', 4)]
