什么时候 len(line.strip()) == 0 你必须增加 empty_line 而且

你可以用这个

 import sys
    def read():
        file_name = input("Name of the file to be read: ")
        try:
            file = open(file_name, 'r')
            lst = []
            line_num = 0
            accept_line = 0
            reject_line = 0
            empty_line = 0
            for line in file:
                line = line.strip() 
                if (len(line.strip()) == 0):
                    line_num += 1
                    empty_line += 1
                if (line == "\n"):
                    line_num += 1
                if (len(line) != 0):
                    line_num += 1
                if (line.isalpha()):
                    accept_line += 1
                    lst.append(line)
                else:
                    reject_line += 1
            print("Read {} lines".format(line_num))
            print("Rejected {} lines".format(reject_line))
        except FileNotFoundError:
            print("open", file_name, "failure.")
            sys.exit(0)
        file.close()
        return lst, accept_line
