Python Forum

I am using Jupyter Notebooks on a Mac 10.13.4 High Sierra , Python 3.6.4.
I want matplotlib to plot (histogram) some data from a sample table (csv file) on my desktop. Its about cars.
Whatever I do I get a syntax error.I have tried changing the slash etc. I am following a Lynda.com tutorial. The tutorial (I am v new to Python) is written for Windows.
What is the accepted way to specify the path for Mac or even Multiplatform for portability - NB I am very inexperienced.

Many thanks
nick

address = /User/aaaaaaaaaa/Desktop/mtcars.csv
cars = pd.read_csv(address)
cars.columns = ['car_names', 'mpg', 'cyl', 'disp', 'hp', 'drat', 'wt', 'qsec', 'vs', 'am', 'gear','carb']
cars.index = cars.car_names
mpg = cars['mpg']

mpg.plot(kind='hist')

SyntaxError: invalid syntax

you need to put in quotes

address = '/User/aaaaaaaaaa/Desktop/mtcars.csv'

Doh, - you are very kind and patient.
