python - 如何在python中访问多行变量的第n行

Question

给定多行变量

var="""this is line 1
this is line 2
this is line 3
this is line 4"""

如何将特定行(比如第 2 行)分配给变量？

Answer 1

>>> var="""this is line 1
... this is line 2
... this is line 3
... this is line 4"""
>>> 
>>> line3 = var.splitlines()[3 - 1]
>>> line3
'this is line 3'

str.splitlines 将您的多行字符串拆分为不同的行。 n 行将在索引 n - 1 处。
