The second to multiply the list by a scalar value is by using a loop and then multiplying each individual element with the scalar value inside the body of the loop. To test this, use the following lines code: demoList=[3,6,9,12,15,18,21] ...
including integers, floating-point numbers, and complex numbers. You can multiply all numbers in the list using many ways, for example, by using thetraversal,numpy.prod(),math.prod(), lambda & reduce(),mul(), traversal by index, reduce...
In Python, you can multiply lists by a number, which results in the list being repeated that many times. However, to multiply the corresponding elements of two Python lists, you need to use a loop or a list comprehension. Example Let me show you an example to understand it better. # Re...

Listing2-1Notice howtext(i.e., “My favorite beasts”)can be displayed next to a variable using a comma in Python 在清单 2-1 中,我们首先定义了一个变量,Fine_Animals,,这是一个适合我们目的的名字。然后我们继续使用 print 命令输出它的内容。这个输出应该是说我最喜欢的野兽:{ '蝙蝠','猫','...
In the first example, we create a new list from an existing list by multiplying each element by 2. b = [e * 2 for e in a] Each of the elements of thealist is multiplied by 2 and the result is added to the newblist. $ ./multiply_elements.py ...
