任何想法我的python代碼有什麼問題？

Question

IHAVE這個代碼

import serial 
import time 
import datetime 
import MySQLdb as mdb 

localtime = time.localtime(time.time()) 

port = serial.Serial("/dev/ttyUSB0", baudrate=9600) 
count = 0 
nomor ='' 
start = '\x02' 
stop = '\x03' 

def mulai(): 
    print "Silahkan tempel kartu anda" 

def no_dosen() 
    print "Dosen tidak terdaftar" 

    mulai() 

def no_jadwal() 
    print "Tidak ada jadwal kuliah" 

    mulai() 

def ada_dosen(dosen) 
    print dosen 
    return 

def ada_matkul(matkul) 
    print matkul 
    return 

def cek_dosen(no) 
    db = mdb.connect("localhost", "azis48", "azis48", "skripsi") 
    cur = db.cursor() 
    cond1 = "SELECT * FROM dosen WHERE kode_dosen = %s" %(no) 
    try: 
     cur.execute(cond1) 
     hitung = cur.rowcount 
     res1 = cur.fetchall() 
     for row in res1: 
      nama_dosen = row[1] 
     if hitung == 1: 
      return nama_dosen 
     elif hitung != 1: 
      return 'null' 
    except: 
     db.close() 

def cek_jadwal(day,time) 
    db = mdb.connect("localhost", "azis48", "azis48", "skripsi") 
    cur = db.cursor() 
    cond2 = "SELECT nama_mk FROM jadwal WHERE hari = '%s' AND waktu = '%s'" %(day,time) 
    try: 
     cur.execute(cond2) 
     hitung = cur.rowcount 
     res2 = cur.fetchall() 
     for row in res2: 
      nama_mk = row[1] 
     if hitung == 1: 
      return nama_mk 
     elif hitung != 1: 
      return 'null' 
    except: 
     db.close() 

def cek_pertemuan(matkul) 
    db = mdb.connect("localhost", "azis48", "azis48", "skripsi") 
    cur = db.cursor() 
    cond3 = "SELECT pertemuan_ke FROM acara WHERE nama_mk = '%s'" %(matkul) 
    try: 
     cur.execute(cond3) 
     res3 = cur.fetchall() 
     for row in res3: 
      pertemuan_ke = row[0] 
     return pertemuan_ke 
    except: 
     db.close() 

def base() 
    day = localtime.tm_wday 
    time = localtime.tm_hour 
    no = str(nomor) 
    dosen = cek_dosen(no) 
    if dosen == 'null': 
     no_dosen() 
    elif dosen != 'null': 
     ada_dosen() 
     matkul = cek_jadwal(day,time) 
     if matkul == 'null': 
      no_jadwal() 
     elif matkul != 'null': 
      ada_matkul() 
      pertemuan = cek_pertemuan(matkul) 
      print pertemuan 

    mulai() 


if __name__ == '__main__': 
    mulai() 
    while True: 
    data = port.read() 
    count += 1 
    if count == 1: 
     if str(data) != start: 
      nomor = '' 
      count = 0 
    elif 2 <= count <= 13: 
     nomor = nomor + str(data) 
    elif count == 16 and str(data) == stop: 
     base(nomor) 
     nomor = '' 
     count = 0 

每次我運行這段代碼，它只是從所有在高清基地（打印ada_dosen功能），如果我用Ctrl停止+ C這裏是回溯

DOSEN3 
Traceback(most recent call last): 
file "skripsi.py", line 111, in<module> 
    base(nomor) 

任何IDE什麼是錯的，所以我的def base（）運行的所有功能？

有在你的代碼中的一些問題，突出了幾個 -

1. 您的所有功能都定義爲def <function name>()，你沒有結束:，不，你應該最有可能是越來越語法錯誤。

2. 您已經定義了base功能def base()，但在節目中你的主要組成部分，你試圖通過傳遞一個參數nomor作爲base(nomor)稱呼它，我想你需要改變功能defnition接受的說法作爲 - def base(nomor):
