Python字符串splitlines()方法

Python splitlines()方法根据行拆分字符串。它在行边界处中断字符串，并返回分割后的字符串列表。换行符可以是新行(\ n)，回车符(\ r)等。下面给出了换行符表，该表将字符串拆分。

此方法在给定的线边界上分割。

Representation	Description
\n	Line Feed
\r	Carriage Return
\r\n	Carriage Return + Line Feed
\v or \x0b	Line Tabulation
\f or \x0c	Form Feed
\x1c	File Separator
\x1d	Group Separator
\x1e	Record Separator
\x85	Next Line (C1 Control Code)
\u2028	Line Separator
\u2029	Paragraph Separator

签名

splitlines([keepends])

参量

keepends：这是一个布尔值，可以为True或False。它是可选的。

它返回逗号分隔的行列表。

让我们看一些splitlines()方法的例子来了解它的功能。

Python字符串splitlines()方法示例1

# Python splitlines() method example
# Variable declaration
str = "Java is a programming language"
# Calling function
str2 = str.splitlines() # returns a list having single element
print(str)
print(str2)
str = "Java \n is a programming \r language"
str2 = str.splitlines() # returns a list having splitted elements
print(str2)

输出：

Java is a programming language
['Java is a programming language']
['Java ', ' is a programming ', ' language']

Python字符串splitlines()方法示例2

将True传递给导致将换行符包含在字符串列表中的方法。请参见下面的示例。

# Python splitlines() method example
# Variable declaration
str = "Java \n is a programming \r language"
# Calling function
str2 = str.splitlines(True) # returns a list having splitted elements
print(str2)

输出：

['Java \n', ' is a programming \r', ' language']

Python字符串splitlines()方法示例3

# Python splitlines() method example
# Variable declaration
str = "Java \n is a programming \r language for \r\n  software development"
# Calling function
str2 = str.splitlines() # returns a list having splitted elements
# Displaying result
print(str2)
# getting back list to string
print("".join(str2)) # now it does not contain any line breaker character

输出：

['Java ', ' is a programming ', ' language for ', '  software development']
Java  is a programming  language for   software development
