The mode can be 'r', 'w' or 'a' for reading (default),writing or appending. The file will be created if it doesn't estwhen opened for writing or appending; it will be truncated whenopened for writing. Add a 'b' to the mode for binary files.Add a '+' to the mode to allow simultaneous reading and writing.If the buffering argument is given, 0 means unbuffered, 1 means linebuffered, and larger numbers specify the buffer size. The preferred wayto open a file is with the builtin open() function.Add a 'U' to mode to open the file for input with universal newlinesupport. Any line ending in the input file will be seen as a '\n'in Python. Also, a file so opened gains the attribute 'newlines';the value for this attribute is one of None (no newline read yet),'\r', '\n', '\r\n' or a tuple containing all the newline types seen.2.be open和open的用法都是isopen3.open 和 opened 的具体区别~~1、意思上的区别①、openadv.敞开的，开着的;坦率的;有议论余地的vt.&vi.（打）开;启动n.公开;野外;空旷vi.使打开;显现vt.开放;张开;开张营业;为（建筑物）揭幕②、openedadj.断开的v.（打）开( open的过去式和过去分词 );睁开;启动2、用法上的区别①、openbe open to 对……开放的be open with 不隐瞒in the open ①在户外,②公开地（de）lay open 把……暴露with open hands 慷慨地②、openedopen的过去式和过去分词3、例句①、openA wasp flew in the open window.一只黄蜂飞进了开着的窗子。heopenedupthe"Messages"程序指给我看。或者零碎的东西散乱在地板上.扩展资料同义词辨析：vi.展开，打开vt.摊开;披露vi.逐渐显露;发展Theoutcomedependsonconditionsaswellashoweventsunfold.结果取决于条件，leaveitfoldeddoubleinyourlap;unfolditcompletely.餐巾如果很大。4.vb open语句用法r表示只读,b表示二进制与此对应的是w表示可写，t表示文本方式打开。再增加一些官方的解释:>print file.__doc__file(name[,mode[,w'a'writing or appending.
