get nth line of string in python

Question

How can you get the nth line of a string in Python 3? For example

getline(\"line1\\nline2\\nline3\",3)

Is there any way to do this

Answer 1

My solution (effecient and compact):

def getLine(data, line_no):
    index = -1
    for _ in range(line_no):index = data.index('\n',index+1)
    return data[index+1:data.index('\n',index+1)]
