问题
I have a website https://www.icsi.in/student/Members/MemberSearch.aspx which when visited, I've to enter the 'CP number' as 16803, & click on search. After that information of student displays which I need to scrap. Can someone please help how to pass the 'CP number' to request & how to press the 'search' button using request.
So far I've tried using the class name & id name as well in param tag of request.get() method.
import requests
r=requests.get('https://www.icsi.in/student/Members/MemberSearch.aspx',params={'dnn_ctr410_MemberSearch_txtCpNumber':16803})
In above code I have tried using param name as: [Class name & id name]
dnn$ctr410$MemberSearch$txtCpNumber
dnn_ctr410_MemberSearch_txtCpNumber
I don't how to work it & I can't use selenium or mechanise like library, can someone please help me.

Finally I tried, & got it working using this,
import requests
from bs4 import BeautifulSoup
import pandas as pd
s=requests.Session()
resp=s.get('https://www.icsi.in/student/Members/MemberSearch.aspx')
resp
soup = BeautifulSoup(resp.content,"html5lib")
dictinfo = {i['name']: i.get('value', '') for i in soup.select('input[name]')}
dictinfo['dnn$ctr410$MemberSearch$txtCpNumber'] = 16803
dictinfo["__EVENTTARGET"] = 'dnn$ctr410$MemberSearch$btnSearch'
dictinfo = {k:(None, str(v)) for k,v in dictinfo.items()}
resp = s.post('https://www.icsi.in/student/Members/MemberSearch.aspx', files=dictinfo)
soup2 = BeautifulSoup(resp.text,"html5lib")
name=soup2.select_one(".name_head").text
#print(name)
info=[str(i.text).strip() for i in soup2.select(".chart_head")]
#print(info)
detail=[str(i.text).strip() for i in soup2.select(".chart_detail")]
#print(detail)
print("Name : ",name)
data=pd.DataFrame({'Info':info,'Details':detail},columns=['Info', 'Details'])
data
Thank you so much to everyone.

website submit button rendering js or ajax request. You should try automation selenium library. it allows you to scrap dynamic rendering request(js or ajax) page data.
from bs4 import BeautifulSoup
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
browser = webdriver.Chrome('/usr/bin/chromedriver')
browser.get('https://www.icsi.in/student/Members/MemberSearch.aspx')
reg = browser.find_element_by_name('dnn$ctr410$MemberSearch$txtCpNumber')
reg.send_keys('16803')
sub = browser.find_element_by_class_name('dnnPrimaryAction')
sub.click()
WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.CLASS_NAME, "rgMasterTable")))
soup = BeautifulSoup(browser.page_source, 'lxml')
table = soup.find("table",{'class':"rgMasterTable"}).find("tr",{'class':"rgRow"})
data = {}
for div in table.find_all("div",{'class':"chart_att"}):
for div2 in div.find_all("div"):
_class = div2.get("class")
if "chart_row" in _class[0]:
key = None
value = None
for td in div2.find_all("td"):
_class1 = td.get("class")
if "chart_head" in _class1[0]:
key = td.text.strip()
else:
value = td.text.strip()
if key is not None and value is not None:
data[key] = value
print(data)

If you are still unable to get the desired result through the requests module then you can automate the curl request and get the work done what the requests will do for you. If you are going to try this method then you just have to change the "CpNumber" attribute value and for doing that you can search for that attribute in the curl request. Hope this will work out for you.
