Level of Difficulty:
Objective: This workout provides practice in creating functions that will join a list of strings.
Problem: Create a function that takes a list of strings as input. Join each string in the list to create and return one complete string. Each word should have a space between them.
Examples:
join_strings(["Hello", "how", "are", "you?"]) -> "Hello how are you?"
join_strings(["What's", "your", "name?"]) -> "What's your name?"
Submission

I forgot to mention to avoid using the join method, but here is an answer.
def join_strings(string_list):
"""
This function takes a list of strings as input and joins them to create one complete string without using .join().
# Initialize an empty string to hold the result
result = ""
# Loop through each string in the list
for string in string_list:
# Add the current string to the result string, followed by a space
result += string + " "
# Remove the trailing space at the end of the result string and return it
return result[:-1]
’ '.join([“Hello”, “how”, “are”, “you?”])
Without using the join() method, you can iterate over the list of strings and concatenate them manually using the + operator.
def join_strings(str_list):
result = ""
for i in range(len(str_list)):
result += str_list[i]
if i < len(str_list) - 1:
result += " "
return result

EDNA AI also give you some great help
I definitely think getting AI assistance here to totally legitimate. This is the future of data science no doubt about it
