Please tell me how to find the maximum number in the file, if the file contains one number in one line? Python

CodePudding user response：

If you have myfile.txt like that:

4
6
7
23
14

then this code

with open("myfile.txt", "r") as f:
    t = []
    for line in f:
        t.append(int(line))
    print(max(t))

will output 23.

I'm not sure this is what you want.

def f_max(filepath):
    with open(filepath, 'r') as f:
        #The readlines() method returns a list of remaining lines of the entire file
        lines = f.readlines()
        #Built-in Function max() return largest item in an iterable
        max_number = max(lines)
        return max_number
