I'm trying to call `spice.str2et(n[i])` for a list of dates (called `UTC`, that I imported from excel). I can get the `spice.str2et(n[i])` but each time it loops it replaces the previous calculated time. I instead need all the `spice.str2et(n[i])` results in an indexed list. (I'm also new to Python/coding, having just started 3 weeks ago.) 

I've tried adding `[i]` after my et in my `et =`. I've also looked up on here how to get indexes from enumerated lists but they are all describe how to get the index from the original list. I'm looking to make a new indexed list. 

```
import spiceypy as spice

n = UTC.iloc[:,0] 

for i, txt in enumerate(n):

    et = spice.str2et(n[i]) #calculates ephermis time for utc, 
    print(et)

```

This then gives me the list of all the ET I want, as it is overwriting each time it loops (When you do print not indented it just gives the last value).
