There is a documented limit of 1000 bytes on R input lines. You are probably hitting it. Try teaching your Python code generator to wrap lines.
NB: input means input from the console or stdin, not to the parser. The front-end is asked for a line of up to 1000 bytes. Some front-ends may supply a longer line, but Rterm.exe will not.
