Challenge 2 of 2 in python basics

Q- Now, make a function named summarize that also takes a list. It should return the string "The sum of X is Y.", replacing "X" with the string version of the list and "Y" with the sum total of the list.

I think the code challenges should be above reviewing what we've learnt. In task 1 it was to 'add the items of a list' which we haven't even learnt about. Can someone please explain the task here? Thanks in advance !

functions.py
```def add_list(list):
sum = 0
for items in list:
sum = sum + items
return(sum)
def summarize(list):
x = ''.join(str(e) for e in list)
y = 0
```

Hello Pandey,

Some tips for this challenge, if you need to increase or decrease the value of your variable you should use the follow: variable += something > this is equivalent to sum = sum + items.

You can also use the str() function to change the list into string.

Have a look my code

```def add_list(items):
sum = 0
for item in items:
sum += item
return sum

def summarize(my_list):
return "The sum of {} is {}".format(str(my_list), add_list(my_list))
```

Here is the way that I solved it, which in my opinion is simpler and uses more of the class's knowledge:

```def add_list(list):
sum = 0
for items in list:
sum += items
return sum

def summarize(list):
