I have some python code where i want to scan and split string on first occurrence of non-allowable characters. import re,string mystring="my_id=abc-something_123&anything#;?lcdkahck;my_id%3Dkckdkkj_bcjc" if "my_id=" in mystring: mystring = mystring[mystring.index("my_id=") + 6 : len(mystring)][0:100] mystring = re.split('[;&#]', mystring)[0] print(mystring) What happens in this, I get string correctly where ;&# is coming, but my data can have any unpredictable character put of ;&#. What i tried drive out these characters allowable_character = '-' + '_' + string.ascii_letters + string.digits mystring = re.sub('[^%s]' % allowable_character, '', mystring) print(mystring) But this just filters the string with characters that are not in 'allowable_character'. What i am trying to achieve is to split string once the character which is not in 'allowable_character' and return that string. So I want expected output as 'abc-something_123' Any help is appreciated here Continue reading...
