有如下值集合 [11,22,33,44,55,66,77,88,99,90...]，将所有大于 66 的值保存至字典的第一个key中，将小于 66 的值保存至第二个key的值中。即： {'k1': 大于66 , 'k2': 小于66}v1 = [11,22,33,44,55,66,77,88,99,90]dicNum = {"k1":[],"k2":[]}for i in v1:    if int(i) > 66:        dicNum["k1"].append(i)    else:        dicNum["k2"].append(i)PRint dicNum["k1"]print dicNum["k2"]print dicNum

v2 = [11,22,33,44,55,66,77,88,99,90]dicNum = {}for i in v2:    if int(i) > 66:        if "k1" in dicNum:            dicNum["k1"].append(i)        else:            dicNum["k1"] = [i]    else:        if "k2" in dicNum:            dicNum["k2"].append(i)        else:            dicNum["k2"] = [i]print dicNum["k1"]print dicNum["k2"]

# 默认字典myDict = collections.defaultdict(list)myDict["k1"].append(1)print myDict["k1"]

# 有序字典 orderdict

有序字典是在字典里面维护了一个列表

#计数器counterlist1 = [11,22,33,44,5544,3322,111]tuple1 = (11,22,33,44,222,5555,2222)str1 = "2343252632642362hfidsafhsifoesagoewagewaglsanldsa;lsf;sahflaf;saf;la"c2 = collections.Counter(str1)print c2

import Queueq = Queue.Queue()q.put(2)q.put(3)q.put(23)print q.get()

练习：<br>有如下列表：    [13, 22, 6, 99, 11] 请按照一下规则计算：13 和 22 比较，将大的值放在右侧，即：[13, 22, 6, 99, 11]22 和 6 比较，将大的值放在右侧，即：[13, 6, 22, 99, 11]22 和 99 比较，将大的值放在右侧，即：[13, 6, 22, 99, 11]99 和 42 比较，将大的值放在右侧，即：[13, 6, 22, 11, 99,] 13 和 6 比较，将大的值放在右侧，即：[6, 13, 22, 11, 99,]...

li = [13, 22, 6, 99, 11]for m in range(len(li)-1):    for n in range(m+1, len(li)):        if li[m]> li[n]:            temp = li[n]            li[n] = li[m]            li[m] = tempprint li

def func(*args):    print argsli = [11,22,33,444,332,112]func(*li)

def func(**args):    print argsdic = {"echo":123,"rep":234}func(**dic)

def email(arg):    print argif __name__ == "__main__":    cpu = 100    ram = 50    disk = 500    for i in range(1):        if cpu > 90:            alert = "cpu 出现问题"            email(alert)        if disk > 90:            alert = "disk 出现问题"            email(alert)        if ram > 80:            alert = "内存 出现问题"            email(alert)

obj = open("index.txt","r")obj.seek(10)#定位指针

print obj.tell()#输出指针位置

print obj.read()#输出内容

print obj.tell()

#输出指针位置
