lookup

问题 I have two csv files.Depending upon the value of a cell in csv file 1 I should be able to search that value in a column of csv file 2 and get he corresponding value from other column in csv file 2. I am sorry if this very confusing.It will probably get clear by illustration CSV file 1 Car Mileage A 8 B 6 C 10 CSV file 2 Score Mileage(Min) Mileage(Max) 1 1 3 2 4 6 3 7 9 4 10 12 5 13 15 And my desired output CSV file is something like this Car Mileage Score A 8 3 B 6 2 C 10 4 Car A is given a

问题 I am trying to update a Lookup field in CRM via the following code. Create a new entity Person Person contains a lookup field HospitalOfBirth from another entity Hospital Value to be inserted: hospitalName I referenced from online articles and drafted my code below. Entity Person = new Entity("Person"); //do I set the value of the field by the following? Person.Attributes[Person.HospitalOfBirth] = hospitalName; Person.Attributes[Person.HospitalOfBirth] = new EntityReference("Hospital", Person

问题 I am trying to match partial data from multiple cells and want value in return. Tried index match and search function but no luck. If anyone can help. Example: Sheet1: Cell "A1": BGRAP1 - Gig0/2/17 BGRAP22 - Gig0/2/16 Cell "A2": BRAMT2 - Gig0/2/0 PTKLP8 - Gig0/2/16 PTKLP1 - Gig0/2/16 PTKLP8 - Gig0/2/17 Cell "B1": S2165 Cell "B2": S2218 Sheet 2: Cell "A1": BGRAP1 Cell "A2": PTKLP8 Cell "A3": BGRAP22 Cell "A4": BRAMT2 Cell "A5": PTKLP8 Cell "A6": PTKLP1 Cell "B1": Gig0/2/17 Cell "B2": Gig0/2/17

问题 Say I have two dfs df = pd.DataFrame({'A': [1, 2, 3,4,5], 'B': [2, 4,2,4,5], 'C': [1, -1, 3,5,10],'D': [3, -4,3,7,-3]}, columns=['A', 'B', 'C', 'D']) df = df.set_index(['A']) df2 = pd.DataFrame({'A': [1, 2, 3,4,5], 'J': ['B', 'B','C','D','C']}, columns=['A', 'J']) df2 = df2.set_index(['A']) and I would like to use df2 to select the columns of df row by row in order to get the following dataframe sel 1 2 2 4 3 3 4 7 5 10 where the first two values are from the column B of df , the third from

问题 I imagine that I have a row with two kinds of alphanumeric values, one that has 0, and another that has a digit above 0. If I want to find the rightmost cell that has a value above 0 such as 1, what would the formula be? Currently I am using the formula =IFERROR(LOOKUP(2,1/(A2:O2<>""),A2:O2),"NS") but it returns MB0 instead of HB1. 回答1: I'd suggest trying like below if number part is always rightmost part of the string. =IFERROR(LOOKUP(2,1/RIGHT(A2:O2),A2:O2),"NS") 来源： https://stackoverflow

问题 i am new to spark. We are currently building a pipeline : Read the events from Kafka topic Enrich this data with the help of Redis-Lookup Write events to the new Kafka topic So, my problem is when i want to use spark-redis library it performs very well, but data stays static in my streaming job. Although data is refreshed at Redis, it does not reflect to my dataframe. Spark reads data at first then never updates it. Also i am reading from REDIS data at first,total data about 1mio key-val

问题 In my previous question(Spark Structured Streaming dynamic lookup with Redis ) , i succeeded to reach redis with mapparttions thanks to https://stackoverflow.com/users/689676/fe2s I tried to use mappartitions but i could not solve one point, how i can reach per row column in the below code part while iterating. Because i want to enrich my per-row against my lookup fields kept in Redis. I found something like this, but how i can reach dataframe columns and add new column looking up to Redis.
