Pandas Dataframe Find Index Of Closest Value

Pandas Dataframe Find Index Of Closest Value - In order to get the single closest value of the given number, we select element at the first index ( 0 ). main.py result = df.iloc[(df['age'] - num).abs().argsort()[:1]] # # first name age net salary # # 0 Alice 20 75 # print (result) Parameters keylabel Returns int if unique index slice if monotonic index else mask Examples unique index pd Index list abc unique index get loc b 1 monotonic index pd Index list abbc monotonic index get loc b slice 1 3 None

Pandas Dataframe Find Index Of Closest Value

There is a lookup function in Pandas but it finds exact values, so if a value doesn't exist then nothing is returned. @GarethRees I implemented params = df.iloc [min (max (9 - round (z / 10), 0), 8)] in the function. This gets rid of the if statements but execution time is the same as my original example. 1 So I am trying to find a vectorized way to do this, say I have a data frame DF1 that contains a timestamp column with a lot of timestamps in increasing order. I also have a list with a target time and I want to use this to find the row or index of that row in DF1 that contains the closest timestamp to that target time.
