17. Tuples to Strings Map

Write a Python program to convert a given list of tuples to a list of strings using the map function.

Sample Solution:

Python Code:

# Define a function named 'tuples_to_list_string' that takes a list of tuples as input
def tuples_to_list_string(lst):
    # Use the 'map' function with 'join' to concatenate elements within each tuple using a space as a separator
    # Convert the map object to a list and return the result
    result = list(map(' '.join, lst))
    return result

# Define a list of tuples named 'colors'
colors = [('red', 'pink'), ('white', 'black'), ('orange', 'green')]

# Print a message indicating the operation to be performed
print("Original list of tuples:")

# Print the original list of tuples
print(colors)

# Print a newline for better readability
print("\n")

# Print a message indicating the operation to be performed
print("Convert the said list of tuples to a list of strings:")

# Print the result of calling the 'tuples_to_list_string' function with the 'colors' list
print(tuples_to_list_string(colors))

# Define another list of tuples named 'names'
names = [('Sheridan', 'Gentry'), ('Laila', 'Mckee'), ('Ahsan', 'Rivas'), ('Conna', 'Gonzalez')]

# Print a newline for better readability
print("\n")

# Print a message indicating the operation to be performed
print("Original list of tuples:")

# Print the original list of tuples
print(names)

# Print a newline for better readability
print("\n")

# Print a message indicating the operation to be performed
print("Convert the said list of tuples to a list of strings:")

# Print the result of calling the 'tuples_to_list_string' function with the 'names' list
print(tuples_to_list_string(names))

Sample Output:

Original list of tuples:
[('red', 'pink'), ('white', 'black'), ('orange', 'green')]

Convert the said list of tuples to a list of strings:
['red pink', 'white black', 'orange green']

Original list of tuples:
[('Sheridan', 'Gentry'), ('Laila', 'Mckee'), ('Ahsan', 'Rivas'), ('Conna', 'Gonzalez')]

Convert the said list of tuples to a list of strings:
['Sheridan Gentry', 'Laila Mckee', 'Ahsan Rivas', 'Conna Gonzalez']
