Python| numpy numpy.ndarray.__imul__()
在numpy.ndarray.__imul__()方法的帮助下,我们可以乘以在 ndarray.__imul__() 方法中作为参数提供的特定值。值将乘以numpy 数组中的每个元素。
Syntax: ndarray.__imul__($self, value, /)
Return: self*=value
示例 #1:
在这个例子中,我们可以看到数组中的每个元素都与 ndarray.__imul__() 方法中作为参数给出的值相乘。请记住,此方法适用于每种类型的数值。
Python3
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.array([1.2, 2.6, 3, 4.5, 5])
# applying ndarray.__imul__() method
print(gfg.__imul__(5))
Python3
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.array([[1, 2.2, 3, 4, 5.01],
[6.1, 5, 4.8, 3, 2]])
# applying ndarray.__imul__() method
print(gfg.__imul__(3))
输出:
[ 6. 13. 15. 22.5 25. ]
示例 #2:
Python3
# import the important module in python
import numpy as np
# make an array with numpy
gfg = np.array([[1, 2.2, 3, 4, 5.01],
[6.1, 5, 4.8, 3, 2]])
# applying ndarray.__imul__() method
print(gfg.__imul__(3))
输出:
[[ 3. 6.6 9. 12. 15.03]
[ 18.3 15. 14.4 9. 6. ]]
