The following is the html code in index.py

         html = "<html><head><title>C Informatics</title></head><body>"
         html += "<h1><center>Hospital Management & Information System</h1><br>"
         html += '<p><br>'
         html += '<p><br>'
         html += '<p><br>'
         html += '<center>'
         html += '<form method="post" action="response.py">'
         html += 'User Name :<input type="text" name="name"><br>'
         html += 'Password&nbsp&nbsp&nbsp:<input type="password"
name="paswd1"><br>'
         html += '<table>'
         html += '<TR/><TD NOWRAP/>Highest Qualifications:'
         html += '<TD/><SELECT name="hiqual"/>'
         html += '<OPTION/>Ph.D / Doctorate'
         html += '<OPTION/>Post Graduation'
         html += '<OPTION/>Post Graduation Diploma'
         html += '<OPTION SELECTED/>Graduation'
         html += '<OPTION/>Diploma'
         html += '<OPTION/>Undergraduate'
         html += '</SELECT/><br>'
         html += '<input type="submit" Value="Log In">'
         html += '</form>'
         html += '</center>'
         html += "</body></html>"
