how to add to numbers in list in python

April 9, 2024

I want to be able to add a number to a number in list. I do not want to add numbers TO a list. I want to add to numbers IN a list. There is just 2 numbers in the list and I want to add to each of those. I want to add the same number to each, 1.

When I tried making a list and just saying list + 1 I got a Type error. Here is what I tried:

my_list = [2 , 3 ]
my_list1 = my_list + 1
print(my_list)

>Solution :

my_list = [2,3]

#Solution 1
my_list = [item +1 for item in my_list]

#Solution 2 
for i in range(len(my_list)):
   my_list[i] += 1
#Solution 3 
my_list = list(map(lambda x: x + 1, my_list))

#Solution 4
import numpy as np
my_list = np.array(my_list) + 1
my_list = my_list.tolist()
