Finding numbers in file

Question

I have a file which contains some numbers how could I take this numbers and get the average?

Answer 1

First of all, you have to define how the data is stored. Are the numbers separated by ',' or by spaces... That's the most important : knowing how your numbers are stored in the file.
I assume all your numbers are written on one line and separated by ','.
- open the file
- read the fisrt line as a string
- split this string at each ',' ; it returns a list containing all the numbers as strings
- convert all elements of that list into int
- print the sum of the list divided by the length of the list

Answer 2

ahhh..... you'll need to use regular expression --"findall" .... sample data would be useful.
What have you been able to do so far?
I've had a go and managed to get it done in three lines of code (four if you include the import re statement) it's easier than you think.
correction;-
Two lines of code if you import statistics module too.

Answer 3

They are separated by spaces
The text has lines contains letters and numbers
