Find how many lines in string

Question

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)

Answer 1

You can do:

len(x.split('n'))

Answer 2

You can split() it and find the length of the resulting list:

length = len(x.split('n'))

Or you can count() the number of newline characters:

length = x.count('n')

Or you can use splitlines() and find the length of the resulting list:

length = len(x.splitlines())

Answer 3

If newline is 'n' then nlines = x.count('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() accepts more characters as newlines: nlines = len(x.splitlines()).

Answer 4

SPAMnEGGSnBEANS = Three lines, two line breaks

So if counting lines, use + 1, or you’ll make a fencepost error:

x.count( "n" ) + 1
