 How to replace all values greater than a given value to a given cutoff?

# Input
np.set_printoptions(precision=2)
np.random.seed(100)
a = np.random.uniform(1,50, 20)

# 1: Using np.clip
np.clip(a, a_min=10, a_max=30)

# 2: Using np.where
print(np.where(a < 10, 10, np.where(a > 30, 30, a)))

# output
[ 27.63  14.64  21.8   30.    10.    10.    30.    30.    10.    29.18  30.
  11.25  10.08  10.    11.77  30.    30.    10.    30.    14.43]
