Why did this guy use '\\n' : Ok so i was watching a python 3 tutorial about how to download a file 
and this is what it kinda looks like 

    from urllib import request
    import requests


    goog="http://realchart.finance.yahoo.com/table.csvs=GOOG&d=8&e=7&f=2016&g=d&a=7&b=19&c=2004&ignore=.csv"
    rp=request.urlopen(goog)
    s=rp.read()

    cp=str(s)
    m=cp.split('\\n')
    dest='goog.csv'
    fw=open(dest,'w')
        for c in m:
          fw.write(c+ '\n')

    fw.close()
    fr=open('goog.csv','r')
    k=fr.read()
    print(k)
Why was split(\\\n) used ??? its true that the code only works properly when you use the double black slashes but why
