add all into in a list together in python

To add all the elements in a list together in Python, you can use the sum() function.

Here's an example:

main.py
my_list = [1, 2, 3, 4, 5]
total = sum(my_list)
print(total)  # Output: 15
74 chars
4 lines

Alternatively, you can use a loop to add up all the elements in the list manually:

main.py
my_list = [1, 2, 3, 4, 5]
total = 0
for num in my_list:
    total += num
print(total)  # Output: 15
100 chars
6 lines

Note that sum() can be used with other iterable types as well, not just with lists. Additionally, it's worth mentioning that the + operator can be used to concatenate two lists together, but it doesn't work as a summation operator for lists. To perform arithmetic operations on lists (like summation), you need to use operator overloading.
