# Now, make a function named summarize that also takes a list. It should return the string "The sum of X is Y.", replacing

WHAT DID I DO WRONG

functions.py
```def add_list(lst) :
result = 5
for item in lst:
result += item
return result
def summarize(lst) :
X = list
Y = add_list(list)
resut = "the sum of {}".format(X, Y)
```

It looks likes a few things could be improved:

1. `def summarize(lst):` needs to be outdented to the same level as `def add_list(lst)`
2. `summarize()` needs a `return resut` statement.
3. `format()` arguments need to match the number of targets "{}". You need another "{}"
PLUS
```def add_list(lst) :
result = 0
for item in lst:
result += item
return result

def summarize(list):
X = list
Y = add_list(list)
result = "The sum of {} is {}".format(X, Y)
return result
```

your result was wrong, You did resut and you didn't add 2 curly brackets to replace X and Y
