Question

我有这个代码

operator delete[]

每次运行此代码时，它只会在def base（）中打印ada_dosen函数，如果我用ctrl + c停止它，这里是追溯

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()

    db = mdb.connect("localhost", "azis48", "azis48", "skripsi")
    cur = db.cursor()

        elif hitung != 1:
            return 'null'
    except:

    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)

            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

任何ide什么错误所以我的def base（）上的所有函数都在运行？

Answer 1

您的代码中存在一些问题，以突出显示一些问题 -

您的所有功能都定义为def <function name>()，您没有结尾:，如果没有，您很可能会遇到语法错误。
您已将base函数定义为def base()，但在程序的主要部分中，您尝试通过将nomor作为{{{{}}来调用它。 1}}，我认为您需要更改函数定义以接受参数为 - base(nomor)

知道我在python上的代码有什么问题吗？
