How to extract the substring between two markers?
Using regular expressions - documentation for further reference
import retext = 'gfgfdAAA1234ZZZuijjk'm = re.search('AAA(.+?)ZZZ', text)if m: found = m.group(1)# found: 1234or:
import retext = 'gfgfdAAA1234ZZZuijjk'try: found = re.search('AAA(.+?)ZZZ', text).group(1)except AttributeError: # AAA, ZZZ not found in the original string found = '' # apply your error handling# found: 1234
regular expression
import rere.search(r"(?<=AAA).*?(?=ZZZ)", your_text).group(0)The above as-is will fail with an AttributeError if there are no "AAA" and "ZZZ" in your_text
string methods
your_text.partition("AAA")[2].partition("ZZZ")[0]The above will return an empty string if either "AAA" or "ZZZ" don't exist in your_text.
