find max in a list, python

Question

hello, I want to open a file and read the content then find max numbers but the code below just prints the length of numbers, not number itself.

list = open ("D:\mass.txt", "r")
cont = list.read()
top = max(cont)
for i in cont:
print(top)

~~~~~result~~~~~

Answer 3

Oh I see, I'm not an expert in python :/

answer from stack overflow:

numbers = [float(line[67:71].rstrip()) for line in input_file]

largest_num = max(numbers)
smallest_num = min(numbers)
total = sum(numbers)
count = len(numbers)
