Here's an example of producing output of an array of hashes, grouped by one of the keys

In this case students is an array of hashes showing student names and the cohort they are enrolled in
The output summarises by cohort and lists the relevant enrolled student names

def print_by_category(students)
  # print the students grouped by cohort
  cohort_array = []
    students.each do |hash|
 cohort_array.push(hash[:cohort]).uniq!
