Here is the code. The problem is even there are matching result, the code keeps turning to the "else" because some row doesn't match.

1. like if the row contains the keyword = print those results and ignore those who don't matches.
2. If nothing else match, then turn to else.

def linear_search_name():
  bookname=input("Enter Title of the Book: ")
  bookfile=csv.reader(open("books.csv", "r"))
  for row in bookfile:
    if bookname.casefold() in row[1].casefold():
     print("ID:", row[0],"\n", row[1],"\n",row[2],"\n",row[3],"\n",row[4],"\n")
    else:
      print("try again")
      linear_search_name()

Noob question, but i hope someone can help. Big thanks!!

Code snippet should work fine for you:

import csv
def linear_search_name():
    bookname=input("Enter Title of the Book: ")
    bookfile=csv.reader(open("copilot-test/stack3.csv", "r"))
    match_flag = False
    for row in bookfile:
        if bookname.casefold() in row[1].casefold():
            print("ID:", row[0],"\n", row[1],"\n",row[2],"\n",row[3],"\n",row[4],"\n")
            match_flag = True
    else:
        if not match_flag:
            print("try again")
            linear_search_name()
    
linear_search_name()
