Question

Write the code for a Python function expand(x) that takes a list of strings, concatenates them, and returns the resulting string repeated three times:

Answer 1

To concatenate a list of strings and repeat the resulting string three times in Python, use the join function and the multiplication operator.

Step-by-step explanation:

To create the Python function expand(x) that concatenates a list of strings and returns the result repeated three times, you can use the join function to combine the strings with an empty space as the separator. Then, you can use the multiplication operator to repeat the resulting string three times. Here's an example:

def expand(x):
concatenated_string = ' '.join(x)
expanded_string = concatenated_string * 3
return expanded_string
