1.read()读取文件内容,以字符串形式返回。可传送一个int参数,表示读取多少个字符。适用于size明确且小。 2.readline()一次读取一行,以字符串形式返回。 3.readlines()一次读取全部内容,以列表形式返回。 with语句自动关闭已经打开的文件,使用方法如下: with open("test.txt", "r", encoding="utf-8") as f:...
文本模式下,既可以写入 Unicode 序列 u'hello world!',也可以写入字节序列 'hello world!'。 >>> f = open('data_2.txt', 'w+') >>> f.write('hello world!') >>> f.write(u'hello world!') >>> f.seek(0) >>> f.read() 'hello world!hello world!' >>> f.close()2. 二进制...

open()调用的是系统命令,即调用的操作系统的方法,本身python是不具有打开文件的权限的。既然调用的是系统命令,自然编码方式是按照系统编码来的,windows中文系统都是gbk编码,因此要将文件打开,写入读取都由str(unicode编码)- 文件内容(utf-8编码)之间转换,所以方法内部肯定封装了对编码的处理。
大多数字符编码的清单较小且处于”fixed”状态,即不再追加新的抽象字符(否则将创建新的清单);其他清单处于”open”状态,即允许追加新字符。例如,Unicode旨在成为通用编码,其字符清单本身是开放的,以便周期性的添加新的可编码字符。 1.2 已编码字符集(CCS) ...

我们在python中输入各国文字都可以,因为Unicode是支持任意字符的。当把字符转化为一些不支持它的编码时,就会报错,示例如下: ASCII中文: >>>a='中文'>>>a.encode('ascii')Traceback(most recent call last):File"<stdin>",line1,in<module>UnicodeEncodeError:'ascii'codec can't encode charactersinposition0-1...
