for loop and if translate from R in Python - Joey21 - Feb-06-2018 Hi everyone, i have a new work in data science. My problem is that i always code in R and in python i have no good experience 1) my code in R Quote: for(i in 1:length(l)) X[,i] = MF[[i]](x) in Python Quote:for i in range(1,1+l.length()): i really don't know if it is right ![]() 2) code in R Quote:if(is.na(sv[1])) l = rep(0,length(V)) else l = sv[-1] Python this is very confusing for me i have noooo ideas ![]() RE: for loop and if translate from R in Python - wavic - Feb-06-2018 It looks simple code but I have not idea what the R code is doing. My eyes hurt looking at it. ![]() Can you explain it or write a pseudo code_ RE: for loop and if translate from R in Python - Joey21 - Feb-06-2018 :D lol ok i will try: 1) i think the for loop is right until X[,i]=MF[[i]](x) and that means from the matrix X i column = ... I give you a example for MF[[]] -> e=[[1,2,3],[4,5,6]] And e[[2]] =4 My english is not so good (sorry) RE: for loop and if translate from R in Python - sparkz_alot - Feb-06-2018 I've never used R either, but it seems you could use a known set of values, plug them into your R program and record the result. Then plug the same values into your Python code and see if you get the same result. |
