## Issue

First-Timer here 🙂

The very simple function geome(x) gives no output, eventhough the exact same code works fine outside of the function (see "z = list …").

What am I doing wrong?

Would very much appreciate some help or hintsThank you.

```
from operator import truediv
x = [1, 2, 4, 8, 16]
z = list(map(truediv, x[1:], x[:-1])) # This Works perfectly fine! >>> Geometric
if all(num == z[0] for num in z):
print('Geometric')
def geome(x):
z = list(map(truediv, x[1:], x[:-1]))
if all(num == x[0] for num in z):
print('Geometric')
geome(x) # Doesn't work, even though it is the same code as above, only inside of a function. >>>
```

## Solution

Your `geome`

implements something different to what you have outside. In the `if`

clause you changed `z[0]`

to `x[0]`

, so `geome`

should be like this instead:

```
def geome(x):
z = list(map(truediv, x[1:], x[:-1]))
if all(num == z[0] for num in z):
print('Geometric')
```
