Making NumPy arrays from lists
Recall how lists can contain anything? They can even contain other lists. In this exercise, you're going to demonstrate this feature and show how useful it is for creating our own NumPy arrays.
Seven lists are loaded into your workspace, each named after a day of the week: monday
, tuesday
, and so on. Each list contains the average hourly bicycle traffic across the Fremont bridge.
This exercise is part of the course
Python for MATLAB Users
Exercise instructions
- Create a list
weekdays
where each element is a daily list, starting on Monday. - Create a NumPy array
traffic
from the listweekdays
. - Calculate the mean hourly traffic.
- Plot the mean hourly traffic for weekdays.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Create a list "weekdays" where each element is a daily list, starting on Monday
weekdays = [____]
# Create a NumPy array "traffic" from the list "weekdays"
traffic = ____(weekdays)
# Calculate the hourly mean traffic
hourly = np.____(traffic,axis=0)
# Plot the mean hourly traffic for weekdays
plt.____(____)
plt.show()
