Hi Manish, def find_distinct_name(file_path,action): try: file = open(file_path, action) lines = file.read().splitlines() name = [] if len(lines)==0: raise Exception("the file is empty") else: for i in range(1,len(lines)): line = lines[i] words = line.split(",") name.append(words[1]) name_list = set(name) print(name_list) except Exception as e: print(e) find_distinct_name("details.txt", "r") o/p = {'"Manish"', '"Rohan"', '"Simaran"', '"Manish'} when reading the file using read option. All the lines are getting converted into strings and when i use split method to get list from lines. I am getting data as "Manish" and "Manish, instead of error. Please let me know if there is a way to read data from txt file along with data type.
