Timestamp is the pandas equivalent of python's Datetime and is interchangeable with it in most cases. It's the type used for the entries that make up a DatetimeIndex, and other timeseries oriented data structures in pandas.
There are essentially three calling conventions for the constructor. The primary form accepts four parameters. They can be passed by position or keyword.
The other two forms mimic the parameters from datetime.datetime
. They can be passed by either position or keyword, but not both mixed together.
Value to be converted to Timestamp.
Offset which Timestamp will have.
Time zone for time which Timestamp will have.
Unit used for conversion if ts_input is of type int or float. The valid values are 'D', 'h', 'm', 's', 'ms', 'us', and 'ns'. For example, 's' means seconds and 'ms' means milliseconds.
Due to daylight saving time, one wall clock time can occur twice when shifting from summer to winter time; fold describes whether the datetime-like corresponds to the first (0) or the second time (1) the wall clock hits the ambiguous time.
Pandas replacement for python datetime.datetime object.
Using the primary calling convention:
This converts a datetime-like string
This example is valid syntax, but we were not able to check execution>>> pd.Timestamp('2017-01-01T12') Timestamp('2017-01-01 12:00:00')
This converts a float representing a Unix epoch in units of seconds
This example is valid syntax, but we were not able to check execution>>> pd.Timestamp(1513393355.5, unit='s') Timestamp('2017-12-16 03:02:35.500000')
This converts an int representing a Unix-epoch in units of seconds and for a particular timezone
This example is valid syntax, but we were not able to check execution>>> pd.Timestamp(1513393355, unit='s', tz='US/Pacific') Timestamp('2017-12-15 19:02:35-0800', tz='US/Pacific')
Using the other two forms that mimic the API for datetime.datetime
:
>>> pd.Timestamp(2017, 1, 1, 12) Timestamp('2017-01-01 12:00:00')This example is valid syntax, but we were not able to check execution
>>> pd.Timestamp(year=2017, month=1, day=1, hour=12) Timestamp('2017-01-01 12:00:00')See :
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
