Any idea why this is not plotting using ggplot

Question

I'm trying to plot a scatter using ggplot but im unable to get it to work, any ideas?

dataframe and packages installed

import numpy as np
from plotnine import *
import matplotlib.pyplot as plt

#scatter plot
locations = accidents[['Latitude','Longitude']]
locations

Latitude    Longitude
0   51.508057   -0.153842
1   51.436208   -0.127949

Code attempted:

(ggplot(locations(x = 'Latitude', y = 'Longitude', colour = 'red')) +
geom_point())

Error code;
