in below I got datetime.date and datetime.datetime class.
start=df.index[0]
start_input_1=datetime.strptime(start_input[:10],'%Y-%m-%d')
print(start_input[:10])
print(type(start))
print(type(start_input_1))
2021-09-01
<class 'datetime.date'>
<class 'datetime.datetime'>
Now if I below comparison, then I got an error of
cannot compare datetime.datetime to datetime.date
if start_input_1>=start:
start_plot=start_date_input_1
so how do I convert datetime.date into datetime.datetime so I can compare two dates?
if I use pd.to_datetime(), it is converted to timestamp instead of datetime. Thanks for your help.
start=pd.to_datetime(start)
print(start)
class 'pandas._libs.tslibs.timestamps.Timestamp'
>Solution :
You can either check if dates are the same by taking date from the datetime object, or add default time (00:00:00) to the date object to make it datetime:
dt = datetime.fromisoformat("2020-01-01T10:00:00")
d = date.fromisoformat("2020-01-01")
print(dt, d) # 2020-01-01 00:00:00 2020-01-01
print(type(dt), type(d)) # <class 'datetime.datetime'> <class 'datetime.date'>
# Check only by date, do not check time
if d == dt.date():
print("Same date")
# Check by date, but both have to be 00:00:00
d = datetime.fromisoformat(d.isoformat())
if d == dt:
print("Same date and 00:00:00")
