Function 将列表/数组的元素乘以 python 中的数字

Question

I want to create a function that receives an array or a list, and then multiply each element by a Integer number, for example 5.

Def Multiply ( ListOrArray )... #Return another list with the same quantity of elements but multiplied by 5.

Answer 1

Functional programming in Python makes it quite easy to implement, as you can see in the following snippet:

my_numbers = [1,2,3,4,5]

results = list(map(lambda x: x*5, my_numbers))

print(results)

Answer 2

Probably you could try the following

list = [1,2,3]
def multiplier (a):
    b =[]
    for i in list:
        i = i*5
        b.append(i)
    return b
a=list
print(multiplier(a))

or

def multiplier(*args):
    b=[]
    for a in args:
        a = a*5
        b.append(a)
    return b
print(multiplier(5,6,7))
