calculateAverageSalary(filename): Returns the average salary of all employees rounded down to 2 decimal points highestHireMonth(filename): Returns the month (integer) during which most hires were made over the years getMonth(date): Helper function to extract and return the month number from a date given as a string input of format MM/DD/YY. Return type should be an int.

An extract from the answer is as follows:

for i in salary:

 total_salary+=float(i)

 count+=1  

return round(total_salary/count,2)

def getMonth(date):

ddate = []

for i in date:

 ddate.append(i.split('/')[0])

mode = int(max(set(ddate), key=ddate.count))

return mode  

def highestHireMonth(filename):

month = []
