Any of those help First of all, I would suggest you to usу requests library instead urllib. Also we need a BeautifulSoup for working with HTML tags:
code :
pip install requests

pip install beautifulsoup4
import requests
from bs4 import BeautifulSoup

session = requests.Session()

payload = {
    r'TopControl1$ScriptManager1': r'HistoriqueNegociation1$UpdatePanel1|HistoriqueNegociation1$HistValeur1$LinkButton1',
    r'__EVENTTARGET': r'HistoriqueNegociation1$HistValeur1$LinkButton1',
    r'__EVENTARGUMENT': r'',
    r'TopControl1$TxtRecherche': r'',
    r'TopControl1$txtValeur': r'',
    r'HistoriqueNegociation1$HistValeur1$DDValeur': r'9000  ',
    r'HistoriqueNegociation1$HistValeur1$historique': r'RBSearchDate',
    r'HistoriqueNegociation1$HistValeur1$DateTimeControl1$TBCalendar': r'22/12/2014',
    r'HistoriqueNegociation1$HistValeur1$DateTimeControl2$TBCalendar': r'28/12/2014',
    r'HistoriqueNegociation1$HistValeur1$DDuree': r'6',
    r'hiddenInputToUpdateATBuffer_CommonToolkitScripts': r'1'
  }


uri = 'http://www.casablanca-bourse.com/bourseweb/en/Negociation-History.aspx?Cat=24&IdLink=225'
r = session.get(uri)

#Find __VIEWSTATE value, there is only one input tag with type="hidden"
soup = BeautifulSoup(r.text)
viewstate_tag = soup.find('input', attrs={"type" : "hidden"})
payload[viewstate_tag['name']] = viewstate_tag['value']

r = session.post(uri, payload)
print r.text #contains html table with data

To fix the issue you can do .text decodes the response content to string, so your imge file will be corrupted.
Instead you should use .content which holds the binary response content.
code :
import requests 

test_image = "https://www-nass.nhtsa.dot.gov/nass/cds/GetBinary.aspx?Image&ImageID=497001669&CaseID=149006692&Version=1"
pull_image = requests.get(test_image)

with open("test_image.jpg", "wb+") as myfile:
    myfile.write(pull_image.content)
pull_image = requests.get(test_image, stream=True)
with open("test_image.jpg", "wb+") as myfile:
    myfile.write(pull_image.raw.read())

it fixes the issue If your aim is to download the zip file after providing the date, this will do the job.
If you inspect the zip file element, you can see that the href is /content/historical/EQUITIES/2018/FEB/cm02FEB2018bhav.csv.zip or /content/historical/EQUITIES/2017/DEC/cm06DEC2017bhav.csv.zip as per the date you enter.
code :
import webbrowser

def download_zip(date, month, year):
    url = 'https://www.nseindia.com/content/historical/EQUITIES/{2}/{1}/cm{0}{1}{2}bhav.csv.zip'.format(date, month, year)
    webbrowser.open(url)

download_zip('02', 'FEB', '2018')
def download_zip(date, month, year):
    url = 'https://www.nseindia.com/content/historical/EQUITIES/{2}/{1}/cm{0}{1}{2}bhav.csv.zip'.format(date, month, year)
    r = requests.get(url)
    location = 'C:/Users/username/Downloads/'  # Change the location as per your OS and your needs.
    filename = 'cm{}{}{}bhav.csv.zip'.format(date, month, year)  # You can name this file anything you want, but with a .zip extension
    with open(location + filename, 'wb') as f:
        f.write(r.content)

help you fix your problem To do this, you first need to understand what the flow of network requests that performs the download. The easiest way is to open the developer tools in the browser you are using. And follow the appropriate requests.
In your case, there is an POST Request, Which returns the exact address to the file. Download it with a GET request.

help you fix your problem The site is requiring Javascript to download the file, but you can try this script:
code :
import re
from math import pow, pi, cos
import requests

# algorithm used by site to compute challenge headers:
def test(Challenge):
    var_arr = [int(c) for c in str(Challenge)][::-1]
    LastDig = var_arr[0]
    var_arr.sort()
    minDig = min(var_arr)
    subvar1 = (2 * (var_arr[2])) + (var_arr[1] * 1)
    subvar2 = int(str((2 * var_arr[2])) + str(var_arr[1]))
    my_pow = pow(((var_arr[0] * 1) + 2), var_arr[1])
    x = (Challenge * 3 + subvar1) * 1
    y = cos(pi * subvar2)
    answer = x * y
    answer -= my_pow * 1
    answer += (minDig * 1) - (LastDig * 1)
    answer = str(int(answer)) + str(subvar2)
    return(answer)

with requests.session() as s:
    text = s.get(url).text
    Challenge, ChallengeId = int(re.findall(r'Challenge=(\d+);', text)[0]), int(re.findall(r'ChallengeId=(\d+);', text)[0])

    headers = {'X-AA-Challenge-ID':str(ChallengeId),
               'X-AA-Challenge-Result':str(test(Challenge)),
               'X-AA-Challenge': str(Challenge),
               'Content-Type': 'text/plain'}

    r = s.post(url, headers=headers)

    r = s.get(url)
    filename = re.findall(r'filename=(.*)', r.headers['Content-Disposition'])[0]

    print('Writing {}'.format(filename))
    with open(filename, 'wb') as f_out:

seems to work fine You should have quote marks around the file name. See 19.5.1 on http://www.w3.org/Protocols/rfc2616/rfc2616-sec19.html i.e.
