The function pyExecp is designed to execute a single line of Python code from within R. Thereby pyExecp tries to emulate the natural interactive Python terminal behavior.
The name pyExecp is short for python execute and print. As the name is indicating the most visual difference between pyExec and pyExecp lies in the printing behavior. For example, executing code{pyExecp(‘“Hello ” + “R!”’)} would show code{‘Hello R!’} in the R terminal, executing code{pyExec(‘“Hello ” + “R!”’)} wouldn’t show anything. Internally pyExec uses PyRun_SimpleString and pyExecp uses PyRun_String with the flag Py_single_input, therefore pyExecp can be used to simulate an interactive Python interpreter behavior.
