Các chuỗi kéo dài trên nhiều dòng có thể được thực hiện bằng cách sử dụng trích dẫn ba Python. Nó cũng có thể được sử dụng cho các bình luận dài trong mã. Các ký tự đặc biệt như tab, nguyên văn hoặc newlines cũng có thể được sử dụng trong các trích dẫn ba. Như cái tên cho thấy cú pháp của nó bao gồm ba trích dẫn đơn hoặc kép liên tiếp. & NBSP;
 

Cú pháp: “”” string””” or ”’ string”’

Lưu ý: Trích dẫn ba, theo tài liệu Python chính thức là tài liệu, hoặc các tài liệu đa dòng và không được coi là nhận xét. Bất cứ điều gì bên trong trích dẫn ba được đọc bởi thông dịch viên. Khi thông dịch viên gặp biểu tượng băm, nó bỏ qua mọi thứ sau đó. Đó là những gì một bình luận được xác định là. & Nbsp; & nbsp; Triple quotes, according to official Python documentation are docstrings, or multi-line docstrings and are not considered comments. Anything inside triple quotes is read by the interpreter. When the interpreter encounters the hash symbol, it ignores everything after that. That is what a comment is defined to be. 
 

Báo giá ba cho chuỗi nhiều dòng

Python3

Tương tự, trích dẫn ba đơn cũng có thể được sử dụng cho cùng một mục đích như hình dưới đây: & nbsp;single triple quotes can also be used for the same purpose as shown below: 

Python3

Lưu ý: Chúng tôi cũng có thể sử dụng # trong nhiều dòng, nhưng trích dẫn ba trông tốt hơn nhiều. & NBSP; We can also uses # in multiples lines, but triple quotes look much better.
 

Báo giá ba lần để tạo chuỗi

Một trường hợp sử dụng khác của trích dẫn ba là tạo ra các chuỗi trong Python. Thêm các ký tự cần thiết trong Trích dẫn ba có thể chuyển đổi các ký tự đó thành chuỗi Python. Các mã dưới đây cho thấy việc sử dụng các báo giá ba để tạo chuỗi: & nbsp; & nbsp;
 

Ví dụ 1: & nbsp; 

Python3

str1

this is a long string that is made up of several lines and non-printable characters such as TAB [ ] and they will show up that way when displayed. NEWLINEs within the string, whether explicitly given like this within the brackets [ ], or just a NEWLINE within the variable assignment will also show up.
