--bcaec51866dc507b3004dd50d952
Content-Type: text/plain; charset=ISO-8859-1

Dear all,

I would appreciate if someone could write a simple python code for the
purpose below:

I have five text files each of 10 columns by 10 rows as follows:

file_one = 'C:/test/1.txt'
file_two = 'C:/test/2.txt' . . .
file_five = 'C:/test/5.txt'

 I want to calculate the mean of first row (10 elements) for each file (5
files), if mean of first column (10 elements) of each file (5 files) is 50.

Thank you in advance.

Keira
