Write a function word_mix(wordlist1, wordlist2) that takes as parameters two lists that contain strings.

Question

Use the following template for EVERY function that you write. The docstring below should be placed inside of the function, just after the function signature.

'''

Purpose:

Parameter(s):

Return Value:

'''

Write a function word_mix(wordlist1, wordlist2) that takes as parameters two lists that contain strings. Have the function return a single string that is the result of concatenating alternating strings from each list, starting with wordlist1, inserting a space character between strings. If the lists do not contain the same number of strings, then continue concatenating strings from the list with more items. Make sure that your final string does not have an extra space character at the end.

Examples (text in bold is returned):

>>> word_mix(['the','brown'],['quick','fox'])

'the quick brown fox'

Answer 1

As with most computer programming questions, there are many ways to answer this question. One idea involves calculating the maximum of the two list lengths and having a for loop from 0 to that length, using the loop variable as the index into the lists. Within the loop, strings from each list can be concatenated, using +=, to a result string, which starts as an empty string. Each time through the loop, it would determine the following:

1. if the index is legal for the first list; if so, concatenate the string at the index in the first list to the result
2. if a string from the first list was just concatenated and a string from the second list will be concatenated; if so, concatenate a space to the result
3. if the index is legal for the second list; if so, concatenate the string at the index in the second list to the result
4. if there are still strings in either list left; if so, concatenate a space to the result so that next time through the loop there will be a space before concatenating either the string from the first list or the string from the second list
