Triangle wave shaped array in Python

Question

What is the most efficient way to produce an array of 100 numbers that form the shape of the triangle wave below, with a max/min amplitude of 0.5?

Triangle waveform in m

Answer 1

Triangle is absolute value of sawtooth.

from scipy import signal
time=np.arange(0,1,0.001)
freq=3
tri=np.abs(signal.sawtooth(2 * np.pi * freq * time))
