The module pySerial provides an interface to communicate with a serial device. However, looking at the configuration of a serial device, for example /dev/ttyS1, there are MANY things to configure:
stty -F /dev/ttyS1 -a
speed 1200 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0;

I am especially interested in the parameter -parodd cs7. Is there a way to configure this parameter from within python, or do I have to call an external command to do this (like stty -F /dev/ttyS1 ...)?

Yes, you can even configure after declaring it
ser = serial.Serial('/dev/ttyS1', 19200, timeout=1, parity=serial.PARITY_ODD)
ser.parity = serial.PARITY_EVEN
ser.bytesize = serial.SEVENBITS
