-----------------------------------------------------------------------------------------

Here is my code?

File = open('numbers.txt',"r")
lines = File.readline()

Explanation / Answer

filename = raw_input("Enter a file name : ")
print 'Reading '+filename
myfile = open(filename)
lines = myfile.readlines()
print 'Found ' + str(len(lines)) + ' numbers.'

number = []

for line in lines:
line = line.strip()
number.append(int(line))

print 'Largest number : '+ str(max(number))
print 'Smallest number : '+ str(min(number))
print 'Average : '+ str(sum(number)*1.0/len(number))
