python小程序 写错

from urllib2 import urlopenreq = urlopen(')content = req.read()print content 或者下面的代码都应该可以 import urllib2req = urllib2.urlopen(')content = req.read()print content 为了提高效率,建议最好先学习一下python基础,再学如何...

我简单改了一下,请题主检验。 a = float(input("请输入三次方程的三次项系数a:"))b = float(input("请输入三次方程的二次项系数b:"))c = float(input("请输入三次方程的一次项系数c:"))d = float(input("请输入三次方程常数项d:"))for i in...

def input_withcheck(prompt, checkfunc): """在输入满足检查条件后返回输入数据""" while True: x = input(prompt) if checkfunc(x): return x

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

for i in [None] + list(range(-1,-len(s),-1)):

SyntaxError: name 'x' is parameter and global x是参数

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...

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

用的python3吧 用python3 读取 默认返回的是bytes 而不是 str (貌似如果全是英文,返回的就是str,而且是utf-8编码,python3.3 for Windows 64位) 返回的是bytes就需要解码为str bytes.decode('编码格式')就行了

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,"...
