python小程序问题

mid = (low + high)/2改为mid = (low + high)//2

def f(): a=input('first number:') b=input('second number:') print(a+' + '+ b +' = ',int(a)+int(b))f()first number:4second number:54 + 5 = 9

我只写一个函数: >>> def littleFunc(): data =[] #初始化列表 for i in range(9):#一个for循环 num = int(raw_input("input a number please: "))#控制输入转为int data.append(num)#放入列表 data.sort()#排序 print data#输出 python的程序...

你的文件是csv,文本格式,不是excel格式,所以用excel方式去打开文本文件就会报错。

import math #导入模块/库for i in range(1,10): #for循环语句 print math.sin(i) #print 输出for j in range(100): if j%2==0: #if 条件判断语句 print j,"是偶数" else: print j,"是奇数"data=[1,2,'c','d',5] #列表print data[2] #列表索引,...

score是str类型,需要转成int. score=int(score)

可能会有的错误: OverflowError: Python int too large to convert to C long 或者 OverflowError: range() result has too many items ,python的Int无限制,但C的int和long都会溢出,因为python的很多函数底层用C实现的,所以python有时也会出现这...

开头加上一行# coding:utf8试试

while True: input = raw_input('Please enter something: ') try: input = int(input) if input%2 == 0: print input," is even number." else: print input," is odd number." except: input = str(input) if not ' ' in input: print input,"...

加了个计数 def han(n,x,y,z): global i i+=1 if n==1: print(x,'-->',z) else: han(n-1,x,z,y) print(x,'-->',z) han(n-1,y,x,z)n = int(input('please input a number:'))i=0han(n,'x','y','z')print(i)
