Did you do as I said and put the hyphen character ("-") at the end of the character array on line 3?

Not sure about you, but I got an error when I ran your code (using your default input). This was a problem I had before that confused me for some time! If you want to match a character within a range, you would use something like "[a-z]". The "-" is the symbol that notifies the parser that you are specifying a range. In your array of symbols, "-" is buried in the middle of them all and the parser thinks you are specifying a range, when you just actually want that character. Solution: put "-" at the end 😉

That part seems to be fine. Like I said, all inputs I try work for me. Can you give me an example of an input that you are trying that hasn't worked?

https://code.sololearn.com/c41H5BJpXMxv/?ref=app Does this print False for you if you don't give any input?

import re pword="Sololearn@8" pattern = r"[@#
amp;_-!?*/\%]" if len(pword) >5: if re.search(r"\d+-",pword): if re.search(pattern,pword): print("True") else: print("False") else: print("False") else: print("False") #Output False

You have a "-" after your "\d+". That would be why it doesn't match a number in that example. But that isn't (edit: wasn't) there in the code you posted.

😳. I don't see the difference, but the code you posted runs. Even after removing "-" mine does not

In the 3th if you said find any numbers with a "-" at the next. It has to be r"\d+" that indicates only one or many numbers.
