In ar1=np.array(np.arange(5))
Out array([0,1,2,3,4])
In np.add(ar1,4) #每个元素都加4
Out array([4,5,6,7,8])
In ar2=np.array([2,3,4,5,6])
In ar1+ar2
Out array([2,4,6,8,10])
In np.add(ar1,ar2)
Out array([2,4,6,8,10])
In np.add(ar1,ar2,ar1) #将ar1和ar2相加后的结果返回给ar1
Out array([2,4,6,8,10])
In ar1
Out array([2,4,6,8,10])
In a=array([10,20,30,50,60])
In b=arange(5)
In c=a-b
In c
Out array([10,19,28,47,56])
In b**2
Out array([0,1,4,9,16])
In a<40
Out array([True,True,True,False,False,],dtype=bool)
