Debit is the best payment type
Answer:
- def average_num_in_file(fileName):
- with open(fileName) as file:
- rows = file.readlines()
-
- sum = 0
- count = 0
- for x in rows:
- sum += float(x)
- count += 1
-
- average = sum / count
- return average
-
- print(average_num_in_file("cans.txt"))
Explanation:
The solution code is written in Python 3.
Firstly create a function that take one parameter, fileName (Line 1).
Open the file stream and use readlines method to read the data from the file (Line 2-3). Create variable sum and count to tract the total of the number from text files and number of data from the file (Line 5-6). Use a for loop to loop over each row of the read data and add the current value of each row to sum and increment the count by one (Line 7-9).
After the loop, calculate the average (Line 11) and return the result (Line 12).
At last, we can test the function by passing the cans.txt as argument (Line 14).
