List comprehensions are used to perform some operation for every element or select a subset of elements that meet a condition. We used a list comprehension to multiply each item in the list by 2.2. # Getting input from the user The error often occurs when getting user input using the built...
demoList[i]=demoList[i]*3#Scalar value print(demoList) In the above code snippet: Create a list variable “demoList”. Initialize a for loop and start it from 0 up to the length of the list by using the len() method. For every iteration, take the element at the “i” index and...
In the above example, we initialized the variablecwith the value 1. We multiplied this with every element of the list and displayed its final value. Further reading: Python concatenate string and int Read more → += in Python Read more → ...
也就是常说的elementwise,需要两个矩阵的大小一样(如果不考虑broadcast的话),multiply函数将两个矩阵相同位置的元素分别相乘,或者直接使用* import numpy as np a = np.array( [ [ 1,2 ], [ 3,4 ] ] ) b = np.array( [ [ 1,2 ], [ 3,4 ] ] ) c = np.multiply( a,b ) d = a * b...
