How can I count the rising edge of a square signals using python?

I have a square signal using the following code. How can I count the rising edges using python?

from scipy import signal
import numpy as np
import matplotlib.pyplot as plot

t = np.linspace(0, 1, 1000, endpoint=True)
plt.plot(t, signal.square(2 * np.pi * 5 * t))

Following image represents my output:

Answer

If your data is super clean (like the signal provided), then just find the number of occurrences when the value is greater than the previous:

np.sum(np.diff(s) > 0) # 5
