There is a sign in button but im not able to find its name on the source page. The url of the web page is http://pict.ethdigitalcampus.com/PICT/
Which method of splinter could i use here?
<td width="214" colspan ="2"><div align="left">
<input type="submit" value="Sign In" onclick="return validate();" style="font-family: Verdana; font-size: 8pt; border: 1px solid #666666; padding-left: 2; padding-right: 2; padding-top: 1; padding-bottom: 1">
<input type="reset" name="reset" value="Reset" style="font-family: Verdana; font-size: 8pt; border: 1px solid #666666; padding-left: 2; padding-right: 2; padding-top: 1; padding-bottom: 1">

To expand on Murali's answer, xpaths are useful in this scenario.
import splinter
browser = splinter.Browser()
browser.visit("http://pict.ethdigitalcampus.com/PICT/")
button = browser.find_by_xpath("//input[@value='Sign In']")
The "//" at the beginning of the xpath allows you to find input elements in any part of the document, to keep the query generic.
