| """Convert timedeltas to seconds | |
| In Python, time differences can take many formats. This function can take | |
| timedeltas in any format and return the corresponding number of seconds, as | |
| a float. | |
| Beware! Representing timedeltas as floats is not as precise as representing | |
| them as a timedelta object in datetime, numpy, or pandas. | |
| Parameters | |
| ---------- | |
| timedelta : various | |
| Time delta from python's datetime library or from numpy or pandas. If | |
| it is from numpy, it can be an ndarray with dtype datetime64. If it is | |
| from pandas, it can also be a Series of datetimes. However, this | |
| function cannot operate on entire pandas DataFrames. To convert a | |
| DataFrame, do df.apply(to_seconds) | |
| Returns | |
| ------- | |
| seconds : various | |
| Returns the total seconds in the input timedelta object(s) as float. | |
| If the input is a numpy ndarray or pandas Series, the output is the | |
| same, but with a float datatype. | |
| """ | |
| try: | |
| seconds = timedelta.total_seconds() | |
| except AttributeError: # no method total_seconds | |
| one_second = np.timedelta64(1000000000, 'ns') | |
| # use nanoseconds to get highest possible precision in output | |
| seconds = timedelta / one_second | |
| return seconds |
