Using px
in ... if ...px... else ...
is not supported. This error is because of the order python evaluates ifelse expressionss. The px.empty
is evaluated before data | px[px.SOME_COLUMN == 40]
is passed to it.
Alternatively, you can use p
:
data | px[px.SOME_COLUMN == 40] | p(lambda x: x if not x.empty else exit()) | px.ANOTHER_COLUMN.astype(str).values[0] | p(print)
from sspipe.
data | px[px.SOME_COLUMN == 40] | p(lambda x: x if not x.empty else exit()) | px.ANOTHER_COLUMN.astype(str).values[0] | p(print)
@mhsekhavat , exit()
shuts down the Jupyter kernel in VScode, I believe it would be better to use None
in this concise syntax, what do you think?
import pandas as pd
df = pd.DataFrame({'col1': [1,2], 'col2': [3,4]})
print(df)
# Conventional syntax
dfc = df[df.col1==2]
if not dfc.empty:
print(dfc.col2.astype("str").values[0])
# sspipe syntax
from sspipe import p, px
( df | px[px.col1==2]
| p( lambda x: print(x.col2.astype("str").values[0])
if not x.empty
else None ) )
from sspipe.
@GitHunter0 you're right. Returning None
makes more sense.
