在编写文件时，如何在Python上指定换行符？

Question

与Java（以字符串形式）相比，您可以执行"First Line\r\nSecond Line"。

那么，为了在常规文件中写多行，您将如何在Python中执行此操作？

Answer 1

这取决于您想做的正确程度。\n通常会做的工作。如果您确实想解决问题，请在os包中查找换行符。（实际上称为linesep。）注意：使用Python API写入文件时，请勿使用os.linesep。随便用\n; Python会自动将其转换为适合您平台的换行符。

Answer 2

新行字符为\n。它在字符串内使用。例：    print 'First line \n Second line' \n换行符在哪里。这将产生结果：First line Second line

Answer 3

您可以分别在新行中编写，也可以在单个字符串中编写，这更容易。例子1输入项line1 = "hello how are you"line2 = "I am testing the new line escape sequence"line3 = "this seems to work"您可以单独编写“ \ n”：file.write(line1)file.write("\n")file.write(line2)file.write("\n")file.write(line3)file.write("\n")输出量hello how are youI am testing the new line escape sequencethis seems to work例子2输入项正如其他人在前面的答案中指出的那样，将\ n放在字符串中的相关点上：line = "hello how are you\nI am testing the new line escape sequence\nthis seems to work"file.write(line)输出量hello how are youI am testing the new line escape sequencethis seems to work
