#Python3 #EOF #EOFError

博客提出一个问题，即编写一个Python程序，该程序要不断从标准输入读取行，直到引发EOFError，然后将这些行以倒序输出，用户可通过键入ctrl - D来表示输入结束。

Question:

Write a Python program that repeatedly reads lines from standard input until an EOFError is raised, and then outputs those lines in reverse order a user can indicate end of input by typing ctrl-D

Solution:

EOF，为End Of File的缩写，通常在文本的最后存在此字符表示资料结束。在微软的DOS和Windows中，读取数据时终端不会产生EOF。此时，应用程序知道数据源是一个终端(或者其它“字符设备”)，并将一个已知的保留的字符或序列解释为文件结束的指明；最普遍地说，它是ASCII码中的替换字符(Control-Z，代码26)。相关推荐：《Python教程》在C语言中，或更精确地说成C标准函数库中...

【Python报错】已解决EOFError: EOF when reading a line

通过检查文件读取逻辑、处理标准输入中的EOF、处理管道或重定向中的EOF、使用异常处理机制以及改进程序逻辑等步骤，可以有效地解决这个错误。这个错误表明程序在尝试从输入流（如文件或标准输入）中读取一行数据时，遇到了文件结束符（EOF，End Of File），但没有成功读取到任何数据。函数从标准输入（通常是键盘）读取数据时，如果用户在没有输入任何内容的情况下直接发送了EOF信号（在Windows中通常是Ctrl+Z后回车，在Unix/Linux中通常是Ctrl+D），也会引发这个错误。在Python编程中，
Python 对海表面温度进行EOF分解与前n模态合成

与开始的eof分解略有不同，在进行分解及可视化的时候，将eof分解得到的空间模态乘以特征值的平方根来更好的展示效果。eof=solver.eofs(eofscaling=2) #空间模态 乘以特征值的平方根。solver=Eof(ssto,weights=wgts) #eof分解。solver=Eof(ssto,weights=wgts) #eof分解。三、前4个模态合成SST并比较合成SST与真实SST的差异。eof=solver.eofs() #空间模态。
