This is one of the many ways to install numpy.

NumPy numerical types are instances of dtype (data-type) objects, each having unique characteristics. The dtypes are available as np.bool_, np.float32, etc.

$ import sys $ sys.path.append("NumPy_path") $ import NumPy import numpy as np import matplotlib.pyplot as plt x= np.arange(0,3*np.pi,0.1) y=np.tan(x) plt.plot(x,y) plt.show() Output – Moving forward with python numpy tutorial, let’s see some other special functionality in numpy array such as exponential and logarithmic function. import numpy as np import matplotlib.pyplot as plt # Compute the x and y coordinates for points on sine and cosine curves x = np.arange(0, 3 * np.pi, 0.1) y_sin = np.sin(x) y_cos = np.cos(x) # Set up a subplot grid that has height 2 and width 1, # and set the first such subplot as active. import numpy as np. Hereafter, you can call Numpy using its alias name np. np.array() np.sum() Working with Numpy. We have imported Numpy, now let us start coding using Numpy. Initially, we have seen Numpy is fast, let us write a code to check that.

Oct 5, 2017 np – create numpy arrays as np[1,3,5], and more. np = numpy + handy tools. It's easy: start by importing np (the alias for numpy): import np.

Step1:-In the windows we have to open the command prompt import numpy as np import matplotlib.pyplot as plt # Compute the x and y coordinates for points on sine and cosine curves x = np. arange (0, 3 * np. pi, 0.1) y_sin = np.
