Print element from a specified position in the list

Question

I need to get you to print the August days number on the list, but without using the:

def how_many_days(month_number):

    """Returns the number of days in a month.
    WARNING: This function doesn't account for leap years!
    """

days_in_month = [31,28,31,30,31,30,31,31,30,31,30,31]

#todo: return the correct value

# This test case should print 31, the number of days in the eighth month, August

print(how_many_days(8))

Answer 1

Your function is not returning any results, you need to call the Return at the end of the function passing the number of the month -1, the -1 is pq the array starts counting at 0 and not at 1

def how_many_days(month_number):
  """Returns the number of days in a month.
  WARNING: This function doesn't account for leap years!
  """
  days_in_month = [31,28,31,30,31,30,31,31,30,31,30,31]
  return days_in_month[month_number - 1]

#todo: return the correct value
# This test case should print 31, the number of days in the eighth month, August
print(how_many_days(8))

Answer 2

There are two errors in your code:

1. The return in his role how_many_days
2. Python needs correct indentation.

For your code to work you need to put the return in function and fix indentation and how python starts in 0 you must return the number of the month - 1, see:

def how_many_days(month_number):
    days_in_month = [31,28,31,30,31,30,31,31,30,31,30,31]
    return days_in_month[month_number-1];
# This test case should print 31, the number of days in the eighth month, August

print(how_many_days(8))

See working on Ideone.

Answer 3

 def how_many_days(month_number):

   """Returns the number of days in a month.
      WARNING: This function doesn't account for leap years!
   """

   days_in_month = [31,28,31,30,31,30,31,31,30,31,30,31]

   return days_in_month[month_number]          
print(how_many_days(7));

That is correct.
