# # Your classmates asked you to copy some paperwork for them. You know that there are 'n' classmates and the paperwork has 'm' pages.

# The output should be two capital letters with a dot separating them.

# Create a function which answers the question "Are you playing banjo?".
# If your name starts with the letter "R" or lower case "r", you are playing banjo!
# The function takes a name as its only argument, and returns one of the following strings:
# name + " plays banjo"
# name + " does not play banjo"
# Names given are always valid strings.

#7
# Write a function findNeedle() that takes an array full of junk but containing one "needle"
# After your function finds the needle it should return a message (as a string) that says:
# "found the needle at position " plus the index it found the needle, so:

# Write a function that takes an array of words and smashes them together into a sentence and returns the sentence.

1. ок
2. нужно попробовать записать без if-else. Оно вроде бы тут не нужно.
3. решение хорошее, но как будто где-то подсмотренное) попробуйте переписать первую строку, чтобы не было переменных через запятую. split возвращает массив (список). Попробуйте через этот список.
4. К решению вопросов нет. Я бы порекомендовал попробовать написать эту функцию самостоятельно. Просто для понимания как она работает. Это будет полезно для более сложных задач.
5. ок
6. В целом ок. Но можно убрать “else”, он в такой ситуации уже не нужен. И можно избавиться от “or” – посмотрите как работает оператор “in” и как он может тут помочь
7. С решением тоже всё ок. Но также рекомендовал бы реализовать эту функцию “index()”.
8. ok
9. else можно убрать
10. ок, но если напишете эту функцию самостоятельно, то будет лучше для развития алгоритмического мышления (:
