查找字符串中有多少行 [英] Find how many lines in string

问题描述

我正在创建一个 python 电影播放器​​/制作器，我想在多行字符串中查找行数.我想知道是否有任何内置函数或函数我可以编写代码来执行此操作:

I am creating a python movie player/maker, and I want to find the number of lines in a multiple line string. I was wondering if there was any built in function or function I could code to do this:

x = """
line1
line2 """

getLines(x)

推荐答案

If newline is '\n' then nlines = x.count('\n').

If newline is '\n' then nlines = x.count('\n').

优点是您不需要像 .split('\n') 那样创建不必要的列表(结果可能因 x.endswith('\n')).

The advantage is that you don't need to create an unnecessary list as .split('\n') does (the result may differ depending on x.endswith('\n')).

str.splitlines() 接受更多字符作为换行符:nlines = len(x.splitlines()).
