from sys import argv

rewind(current_file)

print ("Let's sprint 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 (current_line,current_file)

Thông báo lỗi phía dưới:

this is line 1

this is line 2

this is line 3

Now let’s rewind, kind of like a tape.

Let’s sprint three lines:

1 this is line 1

2 this is line 2

3 <_io.TextIOWrapper name=‘text.txt’ mode=‘r’ encoding=‘UTF-8’>

Bạn nào biết mình bị lỗi gì xin chỉ giúp. Thanks

Vấn đề đã được giải quyết, cảm ơn mọi người xem qua.

nguyên nhân lỗi : print

Đúng ra phải là: print_a_line

[SITUVN.gcd]

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 (current_line,current_file)
print_a_line(current_line,current_file)

print() hay print_a_line()?

print_a_line(), chay mới không báo lỗi
