实现一个函数 count_file(filepath)，功能为读取一个本地路径（由参数filepath指定）的文本文件，统计文本文件中的字数和行数，并返回该文本文件的字数和行数。

代码如下：

input.txt

123456
123
123

main.py

def count_file(filepath):
    with open(filepath, 'r', encoding='utf-8') as fr:
        lines = fr.readlines()
    line_len = len(lines)
    count = 0
    for line in lines:
        _line = line.replace("\n", "")
        count += len(_line)

    return count, line_len


filename = 'input.txt'
word_count, line_len = count_file(filename)
print(f"该文本文件的行数为：{line_len}")
print(f"该文本文件的字数为：{word_count}")

输出为：

该文本文件的行数为：3
该文本文件的字数为：12

如有问题及时沟通

def count_file(filepath):
    with open(filepath, 'r', encoding = 'utf-8') as f:
        rs = [i.strip() for i in f.readlines()]
        return sum([len(i) for i in rs]), len(rs)
    
    
s = count_file(filename)
print(s)

首先先创建一个名为text.txt的文件，再创建一个名为main.py的python脚本

text.txt

1234

main.py

def count_file(filepath):
    with open(filepath, 'r', encoding='utf-8') as f:
        content= [i.strip() for i in f.readlines()]
    return sum([len(i) for i in content]), len(content)

s = count_file('text.txt')
print(s)

输出结果：

[4, 1]
