0.: in this tutorial, you’ll learn how to create a new text file in Python using the

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

0 function.

Sử dụng hàm Open () để tạo tệp văn bản mới

Để tạo một tệp văn bản mới, bạn sử dụng hàm

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

0. Hàm

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

0 có nhiều tham số. Tuy nhiên, chúng tôi sẽ tập trung vào hai tham số đầu tiên:

f = open(path_to_file, mode)

Trong cú pháp này, tham số

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

3 chỉ định đường dẫn đến tệp văn bản mà bạn muốn tạo.

Để tạo tệp văn bản mới, bạn sử dụng một trong các chế độ sau:

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

4 - Mở một tập tin để viết. Nếu tệp không tồn tại, hàm

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

0 sẽ tạo một tệp mới. Mặt khác, nó sẽ ghi đè nội dung của tệp hiện có.

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

6 - Mở một tệp để tạo độc quyền. Nếu tệp tồn tại, hàm

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

0 sẽ gây ra lỗi (

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

8). Nếu không, nó sẽ tạo tệp văn bản.

Ví dụ: sau đây tạo ra một tệp mới có tên

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

9 và viết một số văn bản vào đó:

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

Tập lệnh này tạo một tệp có tên

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

9 trong cùng một thư mục trong đó tệp tập lệnh định vị. Nếu bạn muốn tạo một tệp trong một thư mục được chỉ định, ví dụ:

with open('docs/readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: Python (python)

1, bạn cần đảm bảo rằng thư mục

with open('docs/readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: Python (python)

2 tồn tại trước khi tạo tệp. Nếu không, bạn sẽ nhận được một ngoại lệ. Ví dụ:

with open('docs/readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: Python (python)

Error:

FileNotFoundError: [Errno 2] No such file or directory: 'docs/readme.txt'
Code language: JavaScript (javascript)

Trong ví dụ này, Python nêu ra một ngoại lệ vì thư mục

with open('docs/readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: Python (python)

2 không tồn tại. Do đó, nó không thể tạo tệp

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

9 trong thư mục đó. Để khắc phục sự cố, trước tiên bạn cần tạo thư mục

with open('docs/readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: Python (python)

2 và sau đó tạo tệp

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

9 trong thư mục đó.

Ngoài ra, bạn có thể xử lý ngoại lệ bằng cách sử dụng câu lệnh Try-Except như sau:

try:
    with open('docs/readme.txt', 'w') as f:
        f.write('Create a new text file!')
except FileNotFoundError:
    print("The 'docs' directory does not exist")
Code language: Python (python)

Output:

The 'docs' directory does not exist
Code language: plaintext (plaintext)

Nếu bạn không muốn tạo một tệp văn bản mới trong trường hợp nó đã tồn tại, bạn có thể sử dụng chế độ

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

6 khi gọi hàm

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

0:

with open('readme.txt', 'x') as f:
    f.write('Create a new text file!')
Code language: Python (python)

Bản tóm tắt

Sử dụng chức năng

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

0 với chế độ

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

4 hoặc

with open('readme.txt', 'w') as f:
    f.write('Create a new text file!')
Code language: JavaScript (javascript)

6 để tạo tệp văn bản mới.

Bàn luận Open the file for writing.
Trong khi đọc hoặc ghi vào một tệp, chế độ truy cập chi phối loại hoạt động có thể trong tệp đã mở. Nó đề cập đến cách các tập tin sẽ được sử dụng sau khi nó mở. Các chế độ này cũng xác định vị trí của xử lý tệp trong tệp. Định nghĩa của các chế độ truy cập này như sau: Open the file for reading and writing.

Chỉ nối thêm (‘A,): Mở tệp để viết.

Nối và đọc (‘A+,): Mở tệp để đọc và viết. Python program to illustrate Append vs write mode.

Python3

Khi tệp được mở ở chế độ nối trong Python, tay cầm được định vị ở cuối tệp. Dữ liệu được viết sẽ được chèn vào cuối, sau dữ liệu hiện có. & NBSP;

8 is used in exception handling to make the code cleaner and much more readable. It simplifies the management of common resources like file streams. Unlike the above implementations, there is no need to call file.close() when using with statement. The with statement itself ensures proper acquisition and release of resources.
