Need help Translating PHP to Python

Question

I am using a REST library whose development team only supports PHP. Pretty much everything are finished except translating this part of their PHP code to my Python codebase. the "preg_match" is tough for me, please help.

Their PHP:

function strippadding($string) {
 $slast = ord(substr($string, -1));
 $slastc = chr($slast);
 $pcheck = substr($string, -$slast);
 if (preg_match("/$slastc{" . $slast . "}/", $string)) {
 $string = substr($string, 0, strlen($string) - $slast);
 return $string;
 } else {
 return false;
 }
}

My Python:

def strip_padding_pay2go(string):
 last_string = string[-1]
 slast = ord(last_string)
 slastc = chr(slast)
 pcheck = last_string[:-slast]
 if re.search("/" + str(slastc) + "{" + str(slast) + "}/", string):
 last_char = len(string) - slast
 new_string = string[0: last_char]
 return new_string
 else:
 return False

But i keep failing ( returns False ).

• Matthijs Otterloo: You're looking for python's re module. Take a look at re.findall and re.search.
• Raymond Seger: i updated the question
• deceze: Python regexen don't use delimiters (starting and ending /)...

I got it

def strip_padding_pay2go(string):
 last_string = string[-1]
 slast = ord(last_string)
 slastc = chr(slast)
 pcheck = last_string[:-slast]
 if re.search(str(slastc) + "{" + str(slast) + "}", string):
 last_char = len(string) - slast
 new_string = string[0: last_char]
 return new_string
 else:
 return False
