Here are three ways that work.

>>> # Raw string(r)
>>> s = r'C:\Users\DSule\Desktop\python\nyc.csv'
>>> s
'C:\\Users\\DSule\\Desktop\\python\\nyc.csv'

>>> # Other way /
>>> s = 'C:/User/DSule/Desktop/python/nyc.csv'
>>> s
'C:/User/DSule/Desktop/python/nyc.csv'

>>> # Double up
>>> s = 'C:\\Users\\DSule\\Desktop\\python\\nyc.csv'
>>> s
'C:\\Users\\DSule\\Desktop\\python\\nyc.csv'
