Python String splitlines()

Python字符串splitlines（）

Python String splitlines() function returns the of lines in the string. The line boundaries are not included in the string, unless we provide keepends argument value as True.

Python字符串splitlines（）函数返回字符串的行 。 除非我们将keepends参数值设置为True ，否则字符串中不包括行边界。

Python字符串splitlines（） (Python String splitlines())

The following table shows the characters that are treated as line boundary by splitlines() function.

下表显示了splitlines（）函数将其视为行边界的字符。

Python字符串分成几行 (Python String split into lines)

Let’s look into some examples of splitlines() function.

让我们看一下splitlines（）函数的一些示例。

s = 'Java\nPython\nAndroid'lines = s.splitlines()print(lines)lines = s.splitlines(keepends=True)print(lines)

Output:

输出：

['Java', 'Python', 'Android']['Java\n', 'Python\n', 'Android']

Let’s look at another example with a combination of line feed and carriage return characters.

让我们看一个结合了换行符和回车符的示例。

s = 'Java\n\n\n\nPython\n\r\nAndroid'  # \r\n is treated as a single line boundarylines = s.splitlines()print(lines)lines = s.splitlines(keepends=True)print(lines)

Output:

输出：

['Java', '', '', '', 'Python', '', 'Android']['Java\n', '\n', '\n', '\n', 'Python\n', '\r\n', 'Android']

If you get confused with the output from splitlines() function, test it with keepends as True to understand how the split is performed.

如果您对splitlines（）函数的输出感到困惑，请使用keepends作为True进行测试，以了解如何执行拆分。

Finally, let’s look into some examples with different separator characters.

最后，让我们看一些带有不同分隔符的示例。

s = 'A\tB\vC\fD'lines = s.splitlines()print(lines)lines = s.splitlines(keepends=True)print(lines)s = 'A\x1cB\x1dC\x1eD\x85E\u2028F\u2029G'lines = s.splitlines()print(lines)lines = s.splitlines(keepends=True)print(lines)

Output:

输出：

['A\tB', 'C', 'D']['A\tB\x0b', 'C\x0c', 'D']['A', 'B', 'C', 'D', 'E', 'F', 'G']['A\x1c', 'B\x1d', 'C\x1e', 'D\x85', 'E\u2028', 'F\u2029', 'G']

Python字符串split（）vs splitlines（） (Python String split() vs splitlines())

• We can specify separator in , splitlines() is only meant to split string into list of lines.
  我们可以在指定分隔符，splitlines（）仅用于将字符串拆分为行列表。
• There are slight difference in the split() and splitlines() function working. Let’s see that with examples:

  print("".split('\n'))print("".splitlines())print("Hi\n".split('\n'))print("Hi\n".splitlines())

  Output:

  So with line break as separator, split() returns empty string in the list whereas splitlines() returns empty list.

  print("".split('\n'))print("".splitlines())print("Hi\n".split('\n'))print("Hi\n".splitlines())

  输出：

  因此，使用换行符作为分隔符，split（）返回列表中的空字符串，而splitlines（）返回空列表。
