Can anyone help me in this purpose in python.....

Question

a function that takes an array of numbers as parameter, and return the sum. ( name addArrayElements )

Answer 1

Easy-peasy!
At a glance I have two ways to solve.
1. To use built in function sum()
2. create variable with 0 (zero) initial value. Then pass list from for loop each time adding iteration to the variable

This is how I can explain it in words.
Of course writing in programming lang would be more shorter but, I will not do it

Answer 2

Try to solve it yourself first, then post your attempt if you still need help.
