python - Converting txt file to list and returning line after user input search -

i'm trying have user input telephone number, program open text file, convert list, search list , if phone number found return rest of line (which contains address phone number.

i can return either "phone number not found" or line every single line end output this:

phone number not found phone number not found 0121 254132 18 springfield road phone number not found phone number not found 

---

for line in phonenumbers:      if number in line:         print (line)     else:         print ("phone number not found") 

i know it's because i've put line in phonenumbers don't know how not every line.

try following:

for line in phonenumbers:         if number in line:         print (line)         break else:     print ("phone number not found") 

the else part of for loop , execute if didn't break out of for loop.
