Hi Im currently working with a dataset from IEX and cant seem to convert the time to a value that I can work with.

I looped through the dataframe and converted the values to datetime

```
for i, row in enumerate(df['label']):
df['date'][i]=datetime.strptime(df['label'][i], format)

```

which gave me a new column but I can only access the hour/minute if I index it `df['label'][1].hour` 

when I try to loop through again to pull the values to I get a keyerror: Time

```
for i, row in enumerate(df['date']):
df['Time'][i]=((df['date'][i].hour -9)*60 +df['date'][i].minute)

```
