class zipfile.ZipFile { +open(file, mode) +namelist() +open(file, mode) +read() } 在上面的类图中,我们使用zipfile.ZipFile表示ZipFile类,其中包含了open、namelist和read等方法。 结论 通过本文的介绍,我们了解了如何使用Python以rb模式打开zip文件,并提取其中的内容。我们学习了使用zipfile模块的ZipFile...
# 读写,可以写,内容在文件最开头 with open ( "file.txt" ,'r+' ) as f: #for line in f.readlines(): f.write('r+ ...') # w : 普通的写模式,如文件不存在,则建立 # w+ : 如果文件不存在,则建立 with open ( "file.write2.txt" , 'w+' ) as f: for line in f.read(): pri...
对于Windows 系统而言,含有 b(rb、wb、r+b) 表示以二进制形式打开文件。windows 下的 Python 对文本文件(text files)和二进制文件(binary files)的处理方式不同,2. Python 2 vs Python 3对于Python 3 环境:r:Python 将会按照编码格式进行解析,read() 操作返回的是str rb:也即 binary mode,read()操作返回...
