I am trying to split/extract a portion of the "Time" column so it will only show the hours **and** minutes e.g. 18:15 as opposed to 18:15:34. 

I've seen alot of examples online that use the .str.split() function with highlighting the colon as the delimiter. But that would split the Time column into three columns: hours, minutes, seconds. 

Input Dataframe:

df = 

```
Index   Time
0       18:15:21
1       19:15:21
2       20:15:21
3       21:15:21
4       22:15:21

```

Output Dataframe

df = 

```
Index   Time
0       18:15
1       19:15
2       20:15
3       21:15
4       22:15

```

Thanks :)
