windowsprint文件是加密版的。win10系统一樱亩些重要的PDF文档是加密的,每次都要输入密码衫升才可以打开。也有某些PDF文档的内容已经无保密的意义,每次打开都还需脊塌森要输入密码就会很麻烦。print的完整格式为 print (objects,sep,end,file,flush),其中后面4个为可选参数flush
输出是否被缓存通常决定于 file,但基春如果 flush 关键字参数为 True,流会被强制刷新。
objects
复数,表示可以一次输出多个对象。输出多搏饥耐个肢老对象时,需要用 , 分隔。
end
用来设定以什么结尾。默认值是换行符 \n,我们可以换成其他字符串。
sep
用来间隔多个对象,默认值是一个空格。
file
要写入的文件对象。
