file = open('/Users/yanchao/Desktop/Python文件大小.jpg') file.seek(0, os.SEEK_END) print("File Size is :", file.tell()) 输出: Size of file is : 10834 推荐:Python中使用文件I/O操作 4、使用pathlib模块 Path对象的stat()函数返回文件特征,如“st_mode”、“st_dev”等。此外,统计方法的“...

python print输出文件 python print file,Python3File(文件)方法file对象使用open函数来创建,下表列出了file对象常用的函数:序号方法及描述1file.close()关闭文件。关闭后文件不能再进行读写操作。2file.flush()刷新文件内部缓冲,直接把内部缓冲区的数据立刻写入文件,而

结果说明:Python2中read(size)方法的size参数指定的要读取的字节数,而song.txt文件是UTF-8编码的内容,一个汉字占3个字节,因此12个字节刚好是4个汉字。 Python3 代码语言:javascript 复制 with open('song.txt', 'r', encoding='utf-8') as f: print(f.read(12)) 输出结果: 匆匆那年我们 究竟说 结果...
