rows to columns in data.table R (or Python)

Question

This is something I can't achieve with the reshape2 library for R. I have the following data:

 zone       code        literal
 1: A         14           bicl
 2: B         14           bicl
 3: B         24          calso
 4: A         51           mara
 5: B         51           mara
 6: A         125           gan
 7: A         143          carc
 8: B         143          carc

i.e.: each zone has 4 codes with its corresponding literal. I would like to transform it to a dataset with one column for each of the four codes and one column for each of the four literals:

 zone  code1 literal1   code2 literal2   code3 literal3   code4 literal4    
 1: A    14     bicl      51     mara     125      gan      143   carc
 2: B    14     bicl      24    calso      51     mara      143   carc 

Any easy way to achieve this in R? If not, I would also be comfortable with a solution in Python.
