Do not add stuff to read_data function it should only do that.
If add average function that you have it would look like this.
Then make also a function for total sum.

def average(numbers):
avg = sum(numbers) / len (numbers)
print(f"Average = {avg:.2f}")
def read_data(file_in):
try:
with open(file_in) as nums_file:
numbers = []
for line in nums_file:
numbers.append(int(line))
return numbers
except OSError:
return f"Could not read file: {file_in}"
if __name__ == '__main__':
file_in = 'nums.txt'
numbers = read_data(file_in)
average(numbers)
