Alright, I’m just getting started with this book and love it so far. But I encountered kind of a weird bug with exercise 20. Here is my code–which to the best of my understanding matches the book exactly.
EDIT: I am running python 3.7
from sys import argv script, input_file = argv def print_all(f): print(f.read()) def rewind(f): f.seek(0) def print_a_line(line_count, f): print(line_count, f.readline()) current_file = open(input_file) print("First let's print the whole file:\n") print_all(current_file) print("Now let's rewind, kind of like a tape.") rewind(current_file) print("Let's print three lines:") current_line = 1 print_a_line(current_line, current_file) current_line = current_line + 1 print_a_line(current_line, current_file) current_line = current_line + 1 print_a_line(current_line, current_file)
But my output is:
My possible idea is that for some reason the txt is in the wrong encoding version? Any other thoughts or fresh eyes that are seeing what I’m doing wrong? Thanks!
