Answer:Here is one way to calculate the average of all the numbers stored in a file named "numbers.txt" in Python:
Step-by-step explanation:
# Open the file for reading
with open("numbers.txt", "r") as file:
# Read all the lines in the file
lines = file.readlines()
# Convert each line to an integer
numbers = [int(line.strip()) for line in lines]
# Calculate the sum of the numbers
total = sum(numbers)
# Calculate the average by dividing the total by the number of numbers
average = total / len(numbers)
# Print the result
print("The average of the numbers is", average)
