Exercise: Slicing lists 2

3.6.3.5. Exercise: Slicing lists 2#

Let’s get back to the spatial parameters of gait measured previously. For a given participant, we recorded this y:

# y-coordinates of each heel strike, in meters
y = [0.13, 0.72, 1.29, 1.93, 2.55, 3.12, 3.71, 4.34, 4.95, 5.56]

If we know that the first element of y always corresponds to the y-coordinate of the right foot, write a 2-line code that separates y into two lists:

  • y_right, which contains the y-coordinates of all heel strikes for the right foot

  • y_left, which contains the y-coordinates all heel strikes for the left foot

Hide code cell content 
y_right = y[0::2]
y_left = y[1::2]

# Print the results
print(f"Right foot: {y_right}")
print(f"Left foot: {y_left}")

Right foot: [0.13, 1.29, 2.55, 3.71, 4.95]
Left foot: [0.72, 1.93, 3.12, 4.34, 5.56]
