Python in dòng cuối cùng của chuỗi

Vòng lặp

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

1 được sử dụng để lặp qua từng phần tử của một lần lặp trong Python. Chúng ta có thể sử dụng vòng lặp

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

1 để lặp qua từng dòng bên trong một tệp một cách tuần tự và sau đó đọc dòng cuối cùng của tệp. Đoạn mã sau chỉ cho chúng ta cách đọc dòng cuối cùng của tệp bằng vòng lặp

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

1

with open['file.txt', 'r'] as f:
    for line in f:
        pass
    last_line = line
print[last_line]

đầu ra

Chúng tôi đã mở tệp

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

4 ở chế độ

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

5 và sử dụng vòng lặp

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

1 để lặp qua từng dòng trong tệp. Chúng tôi đã sử dụng từ khóa

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

7 để giữ cho vòng lặp trống. Từ khóa

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

7 này hoạt động như một dòng trống trong Python và được sử dụng khi chúng ta không muốn viết bất kỳ mã nào bên trong vòng lặp hoặc câu lệnh điều kiện. Chúng tôi lưu trữ dòng cuối cùng bên trong biến

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

1 khi vòng lặp kết thúc và in giá trị của nó

Đọc dòng cuối cùng của tệp với hàm

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

2 trong Python

Hàm

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

3 đọc tất cả các dòng của tệp và trả về chúng dưới dạng danh sách. Sau đó, chúng tôi có thể lấy dòng cuối cùng của tệp bằng cách tham chiếu chỉ mục cuối cùng của danh sách bằng cách sử dụng

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

4 làm chỉ mục. Ví dụ mã sau đây cho chúng ta biết cách đọc dòng cuối cùng của tệp bằng hàm

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

3 của Python

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

đầu ra

Chúng tôi đã mở tệp

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

4 ở chế độ

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

5 và sử dụng

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

8 để đọc dòng cuối cùng của tệp. Chúng tôi đã sử dụng

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

9 vì hàm

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

2 trả về tất cả các dòng ở dạng danh sách và chỉ mục

with open['file.txt', 'r'] as f:
    last_line = f.readlines[][-1]
print[last_line]

9 này cung cấp cho chúng tôi phần tử cuối cùng của danh sách đó

Trong Python, không có phương thức nào có thể đọc trực tiếp dòng cuối cùng của tệp. Vì vậy, chúng ta phải đọc toàn bộ tệp một cách tuần tự cho đến khi đến dòng cuối cùng. Phương thức đầu tiên đọc từng dòng tệp, trong khi phương thức thứ hai đọc tất cả các dòng cùng một lúc

Cho một số dòng văn bản trong một chuỗi, mỗi dòng được phân tách bằng ký tự ‘\n’. In N dòng cuối cùng. Nếu số dòng nhỏ hơn N thì in tất cả các dòng

Khuyến khích. Vui lòng thử cách tiếp cận của bạn trên {IDE} trước, trước khi chuyển sang giải pháp

Một cách tiếp cận cho vấn đề này đã được thảo luận trong Tập 1 khi chỉ có 10 dòng được in. Trong bài đăng này, một cách tiếp cận khác được thảo luận để in N dòng cuối cùng.  

thuật toán

• Tách chuỗi xung quanh '\ n' bằng cách sử dụng strtok
• Lưu trữ các chuỗi riêng lẻ trong một vectơ
• In N chuỗi cuối cùng từ vector

Dưới đây là việc thực hiện các phương pháp trên
