Hướng dẫn split text file python
I am working on text files like this: Show
with delimiters like "chapter", "Chapter", "CHAPTER", etc... and 1 or 2 digits ("Chapter 1" or "Chapter 01"). I
managed to open and read the file in Python, with
Now I need to split my string, in order to get text for "Chapter XX". For Chapter 02, that would be :
I'm new to Python, I read about regex, match, map, or split, but... well... (I'm writing a Gimp Python-fu plugin, so I use Python version bundled in Gimp, which is 2.7.15). Hàm split() trong Python chia chuỗi theo delimeter đã cho (là space nếu không được cung cấp) và trả về danh sách các chuỗi con; nếu bạn cung cấp đối số num thì chia chuỗi thành num + 1 chuỗi con. Cú pháp của split() trong Python: Chi tiết về tham số: str: Đây là bất kỳ phân chia chuỗi - delimeter nào, mặc định là khoảng trống. num: Số chuỗi con num + 1 được tạo
ra. Ví dụ sau minh họa cách sử dụng của split() trong Python. Chạy chương trình Python trên sẽ cho kết quả: You have the right idea with escaping the backslashes, but despite how it looks, your input string doesn't actually have any backslashes in it. You need to escape them in the input, too! Nội dung chính

You could also use a raw string literal for the input, if it's likely to have many backslashes. This notation is much cleaner to look at (IMO), but it does have some limitations: read the docs!
