Using range() and List ComprehensionsLet’s take a step back and look at what other tools you could use to create an evenly spaced range of numbers. The most straightforward option that Python offers is the built-in range(). The function call range(10) returns an object that produces the...
Thearangefunction returns an evenly spaced list of values within the given interval. s = np.sin(2.5 * np.pi * t) We get thesinvalues of the data. plt.plot(t, s) We draw the line chart with theplotfunction. Matplotlib bar chart ...
