Here, thenp.divide()function is used to perform division ofnumeratorby a scalardenominatorvalue of2. Example 2: Divide NumPy Array by 0 importnumpyasnp numerator = np.array([10,20,30]) denominator = np.array([2,0,10])# perform element-wise division of the numerator array by the denomi...
c = np.divide(a, b) print(c) # Output: [0.25, 0.4, 0.5] 也可以使用/运算符: c = a / b print(c) # Output: [0.25, 0.4, 0.5] 再次说明:上述所有函数都是在输入数组上以element wise的方式应用的,也就是逐元素方式,所以它们返回一个与输入形状相同的数组。
