注意：中位数，要先把所给各个数字按照大小顺序排列 。这是中位数的定义 。所以修改代码如下：
'''myList=[12,34,45,34,34,4]def fZhongWei(myList):myList.sort()N=len(myList)if N%2==1:zhong=myList((N+1)//2)else:zhong=(myList(N//2)+myList(N//2-1))//2#应该是方括号return zhongzhong=fZhongWei(myList)print(zhong)#列表 。'''myList=[1,2,4,5]def fZhongWei(myList):myList.sort()N=len(myList)if N%2==1:zhong=myList[(N+1)//2-1]else:zhong=(myList[N//2-1]+myList[N//2])//2return zhongzhong=fZhongWei(myList)print(zhong)
质因数 质数
求质数或者质因数，代码如下：
def isPrime(N):if N<2:return Falseif N==2:return Truefor i in range(2,N):if N%i==0:return Falseelse:return TrueprimeList=[i for i in range(1,1000) if isPrime(i)==True]def myIsPrime(N):i=2while i1:#while条件可以尝试以最后结果为准 。求质数，从2，3……一直到N,i1if N%i==0:N=N//imyList.append(i)print(i)input()else:i+=1return myListprint(ZhiYinShu(1468))
寻找质因数，需要用到循环语句 。
def ZhiYinShu(N):i=2myList=[]while N>1:#while条件可以尝试以最后结果为准 。求质数，从2，3……一直到N,i1if N%i==0:N=N//imyList.append(i)print(i)input()else:i+=1return myListN=int(input(":"))for i in range(2,N):#for循环中i每次自动加了1，while循环中i得手动加1while N>1:if N%i==0:print(i)N=N//icontinueelse:breakelse:break
随机数
随机数，需要用大函数 。
import randomprint(random.choice(range(1,1000)))#输出1000以内的随机数
复杂数据 图片文本
文本数据本质就是字符串 。对于字符串的操作，可以应用到文本上面 。
打开docx文本
import docxfile=docx.Document("test.docx")wfile=open("result.txt","w",encoding="utf-8")for p in file.paragraphs:line=p.textif "＝" in line:line=line.strip("＝")print(line,file=wfile)else:myline=line.split(" ")for word in myline[3:]:print("\t",word,sep=" ",end="",file=wfile)print("\n",file=wfile)wfile.close()
对文本切分
按照行，按照逗号切分
rFile=open("HZ.txt","r",encoding="utf-8")rData=http://www.kingceram.com/post/rFile.read()rFile.close()rData=rData.split("\n")for line in rData[:10]:tmp=line.split(",")print(tmp[0],"对应的数据是",tmp[1],tmp[2])
