PYTHON 程序问题？

Posted 2023-02-14

有10组数据（每组数据带数字行数在5-9行之间）（在下面展示了3组），
每组数据为了方便整体输出和前面的程序，我把他们弄成了string：（下面是第一组数据
fatloss = "\nGym workout for fat loss\n\nPlate thrusters (15 reps x 3 sets)\nMountain climbers (20 reps x 3 sets)\nBox jumps (10 reps x 3 sets)\nLounges (10 reps x 3 sets)\nRenegade rows (10 reps x 3 sets)\nPress ups (15 reps x 3 sets)\nTreadmill (15 mins x 2 sets)\nSupermans (15 reps x 3 sets)\nCrunches (20 reps x 3 sets)"

只需要输出其中任意一组（根据之前的输入来决定输出谁）
主要问题：其中每组数据（每个string）的每一行的标红项，都需要被提取出来，并带入到我的计算def中的x进行计算，再用计算结果（ans）分别替换掉一开始的标红数据，得到一个被输出的str
不能用的：for loop, lambda functions, classes, all standard imported modules except math.

def answer(x,a): #Calculet the extraction of reps/mins (x for reps/mins,a for age,ans for final reps/mins
if 60 < a <= 65:
ans = x*(1-1/100*(a-60))
elif a <= 75:
ans = x*(1-5/100-2/100*(a-65))
elif a <= 80:
ans = x*(1-25/100-3/100*(a-75))
if a > 80 or 40/100+4/100*(a-80) > 80 :
ans = min((40/100+4/100 *(a-80)),80)
return ans

不确定是不是你要的东西，但姑且可以当参考吧。

python爬虫程序有问题

代码如下 问题应该出在gethtml(url)函数，gethtml(url)的返回值是<function gethtml at 0x0000000003476F98>。请问应该怎么修改？
import re
import urllib

def gethtml(url):
page = urllib.urlopen(url)
html = page.read()
return html

def getpicture(html):
reg = r'src=(.*?\.jpg)'
picturere = re.compile(reg)
picturelist = re.findall(picturere,html)
x=0
for pictureurl in picturelist:
urllib.urlretrieve(pictureurl,'%s.jpg' %x)
x+=1
url = raw_input("url:")
增加一句
html = gethtml(url)
这样修改之后，能运行一段时间，然后会报错：
File "F:\Program Files (x86)\python\Lib\urllib.py", line 477, in open_local_file
raise IOError(e.errno, e.strerror, e.filename)
标注的代码为：
raise IOError(e.errno, e.strerror, e.filename)
这是为什么呢？

IOError就说明你抓取的URL连接失效,在getpicture里加一个try except,无法打开链接时,

没有办法，继续执行下一个Url

import sys
        try:
            urllib.urlretrieve(pictureurl,'%s.jpg' %x)
        except:
            print "Unexpected error:", sys.exc_info()[0]

追问

我改成这样了，的确能检测到失效链接，但是还是会报错

追答

放的位置不对。。。

你错误的地方是urllib.urlretrieve(pictureurl,'%s.jpg' %x)

所以把这一行改为

        try:
            urllib.urlretrieve(pictureurl,'%s.jpg' %x)
        except:
            print "Unexpected error:", sys.exc_info()[0]

参考技术A 帮你慢慢看~~~追问

我在想会不会是那个图片文件的连接失效了，才会出错。
