EDA plots II

Another idea that comes to mind is that the price of a ride could change during the day.

Your goal is to plot the median fare amount for each hour of the day as a simple line plot. The hour feature is calculated for you. Don't worry if you do not know how to work with the date features. We will explore them in the chapter on Feature Engineering.

# Create hour feature
train['pickup_datetime'] = pd.to_datetime(train.pickup_datetime)
train['hour'] = train.pickup_datetime.dt.hour

# Find median fare_amount for each hour
hour_price = train.____('____', as_index=False)['____'].____()

# Plot the line plot
plt.plot(hour_price[____], hour_price[____], marker='o')
plt.xlabel('Hour of the day')
plt.ylabel('Median fare amount')
plt.title('Fare amount based on day time')
plt.xticks(range(24))
plt.show()
