python - How do I multiply each element in a list by a number? -

i have list:

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

how can multiply each element in my_list 5? output should be:

[5, 10, 15, 20, 25]

you can use list comprehension:

my_list = [1, 2, 3, 4, 5] my_new_list = [i * 5 in my_list]  >>> print(my_new_list) [5, 10, 15, 20, 25]

note list comprehension more efficient way for loop:

my_new_list = [] in my_list:     my_new_list.append(i * 5)  >>> print(my_new_list) [5, 10, 15, 20, 25]

as alternative, here solution using popular pandas package:

import pandas pd  s = pd.series(my_list)  >>> s * 5 0     5 1    10 2    15 3    20 4    25 dtype: int64

or, if want list:

>>> (s * 5).tolist() [5, 10, 15, 20, 25]
