How to fix "'TypeError: datetime.time' object is not subscriptable"

I'm working on extracting data time and calculating there results but 00:00:00 values display in a different manner. Why is that ? and how can i fix it?"

I have already tried to read it as a string get a sublist of char and converted to a integer."

Ts = datetime.timedelta(hours = 0, minutes = 0, seconds = 0)
for i in range(0,len(cell_sl)):
    for item in cell_sl:
        trans = item[i]
        Ts = Ts + datetime.timedelta(
                hours=int(str(trans[:2])),
                minutes=int(str(trans[3:-3])),
                seconds=int(str(trans[6:]))
        )


print(Ts)

I expect the output to be for example 00:25:18, but I get TypeError: 'datetime.time' object is not subscriptable

Solution

Either your trans or your item values are datetime.time object's - thats what the error tells you:

TypeError: 'datetime.time' object is not subscriptable

You cannot slice/subscript them like f.e. strings:

trans = item[i]        # <-- this is a "subscription"  ...  either item is a datetime 
Ts = Ts + datetime.timedelta(hours= int(str(trans[:2])),  # or trans is one
                               minutes= int(str(trans[3:-3])), 
                               seconds= int(str(trans[6:])))

Use the hour, minute, second attributes provided by datetime.time instead:

Ts = Ts + datetime.timedelta(hours = trans.time.hour, 
                             minutes = trans.time.minute, 
                             seconds = trans.time.second)

If you are unsure which one is it, use print(type(item)) to see what type it is.

Full example with one datetime value:

import datetime

Ts = datetime.timedelta(hours = 0, minutes = 0, seconds = 0)

print(Ts)

now = datetime.datetime.now()
Ts += datetime.timedelta(hours=now.hour, minutes=now.minute, seconds=now.second)

print(Ts)

Output:

0:00:00
10:24:17
