I'm searching for this string in the Yahoo Finance web page source "CrumbStore":{"crumb":"abcdEFGHijklm"}

I understand that the following code compiles a regex that searches for the string above and assigns it to pattern

pattern = re.compile('.*"CrumbStore":\{"crumb":"(?P<crumb>[^"]+)"\}')

I need to understand what '.* does?

Also, the \.

Also the (?P<crumb>[^"]+)"\}'

Go to www.regular-expression.info and read the tutorial. `.` is one of the most basic regular expression operators. – Barmar May 25 '17 at 09:46
You need an explanation for the quotes at the beginning and end of the string, too? – Barmar May 25 '17 at 09:47
