Using Serial.available() to break while loop

hello friends,
i'm trying exit infinite while loop when arduino receives new command python via serial. code essentially:

code: [select]


while(!serial.available()) {
    //do stuff
}


but though i'm sending things python, condition never met , loop never breaks. i've tried using non-infinite loop in order make sure sending python, , works expect, once infinite loop implemented, it's if nothing being sent.
i've tried:

code: [select]


while(1) {

    //do stuff

    if(serial.available() > 0) {
        break;    }
}


perhaps can't checking new serial input inside while loop? suggestions appreciated!

hi janizer, when reading serial (pseudocode follow);

code: [select]


some_type result;
while (result not expect be){
    while(serial.available()){
         result = read serial
         do stuff result if it's case
     }
}

hope helps : )
