Convert heterogeneous list to string.

Write a Python program to convert a given heterogeneous list of scalars into a string.

Sample Solution:

Python Code:

# Define a function to convert a heterogeneous list of scalars into a string
def heterogeneous_list_to_str(lst):
    # Use the join() method to concatenate the string representations of each element in the list
    result = ','.join(str(x) for x in lst)
    
    # Return the resulting string
    return result

# Initialize a heterogeneous list of scalars
h_data = ["Red", 100, -50, "green", "w,3,r", 12.12, False]

# Print the original list
print("Original list:")
print(h_data)

# Print a newline for better formatting
print("\nConvert the heterogeneous list of scalars into a string:")

# Call the function to convert the list into a string and print the result
print(heterogeneous_list_to_str(h_data)) 

Sample Output:

Original list:
['Red', 100, -50, 'green', 'w,3,r', 12.12, False]

Convert the heterogeneous list of scalars into a string:
Red,100,-50,green,w,3,r,12.12,False
