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
