Hi @Peque,
I can support the Series with DatetimeIndex and the case with DataFrame will be simply df.apply(xirr)
You can use the following code with the current implementation:
# for Series
xirr(s.reset_index())
xirr(s.index, s)
# for DataFrame
df.apply(lambda col: xirr(col.reset_index()))
df.apply(lambda col: xirr(col.index, col)
from pyxirr.
@Peque , I don't think so. I would like a clear separation between "Invalid input" case and "does not converge" case.
You can use something like this:
def suppress(func):
def wrapper(*args, **kwargs):
try:
return func(*args, **kwargs)
except InvalidPaymentsError:
return None
return wrapper
df.apply(suppress(xirr))
from pyxirr.
@Anexen Do you think it would make sense to return NaN
instead of raising exceptions?
This would allow for df.apply(xirr)
to work fine when possible.
In example:
from pandas import DataFrame
from pandas import date_range
from pyxirr import xirr
timezone = "Europe/Madrid"
index = date_range("2000-01-01", periods=10, freq="Y", closed="left", tz=timezone)
df = DataFrame(index=index, data={"a": 10, "b": 10})
df.iloc[0]["a"] = -25
df.apply(xirr)
Would return 0.3774630471754315, NaN
.
