Visualize the walk
Let's visualize this random walk! Remember how you could use matplotlib to build a line plot?
import matplotlib.pyplot as plt
plt.plot(x, y)
plt.show()
The first list you pass is mapped onto the x axis and the second list is mapped onto the y axis.
If you pass only one argument, Python will know what to do and will use the index of the list to map onto the x axis, and the values in the list onto the y axis.

Intermediate Python
Anleitung zur Übung
Add some lines of code after the for loop:
- Import
matplotlib.pyplotasplt. - Use
plt.plot()to plotrandom_walk. - Finish off with
plt.show()to actually display the plot.
