python 2 R
The hash package even offers dictionary-like structure. However, as others said, it is difficult to try to map one language facilities onto another (even if this is what Comparison of programming languages actually offers) without a clear understanding of what it is supposed to be used to.
For example, I can mimic Python zip() in R as follows:
In : x = [1,2,3] In : y = [4,5,6] In : zip(x, y)
Out: [(1, 4), (2, 5), (3, 6)]
> x <- 1:3 > y <- 4:6 > list(x, y) # gives a simple list > as.list(paste(x, y)) # three tuples, as a list of characters > mapply(list, x, y, SIMPLIFY=F) # gives a list of 3 tuples > rbind(x, y) # gives a 2x3 matrix
As can be seen, this really depends on what you want to do with the result afterwards.
