Hướng dẫn how do you give a space between characters in python? - làm cách nào để tạo khoảng cách giữa các ký tự trong python?

Question

Cách pythonic

Một cách rất pythonic và thiết thực để làm điều đó là bằng cách sử dụng phương thức chuỗi join():

Cách pythonic

str.join(iterable)

Các tài liệu Python chính thức cho biết:

Trả về một chuỗi là sự kết hợp của các chuỗi trong Itable ... Bộ phân cách giữa các phần tử là chuỗi cung cấp phương pháp này.

Làm thế nào để sử dụng nó?

Hãy nhớ rằng: Đây là một phương thức chuỗi.

Phương pháp này sẽ được áp dụng cho

iterable = "BINGO"
separator = " " # A whitespace character.
                # The string to which the method will be applied
separator.join(iterable)
> 'B I N G O'

0 ở trên, trong đó phản ánh chuỗi sẽ được sử dụng làm phân tách của các mục trong ITable.

Hãy có một số ví dụ thực tế!

iterable = "BINGO"
separator = " " # A whitespace character.
                # The string to which the method will be applied
separator.join(iterable)
> 'B I N G O'

Trong thực tế, bạn sẽ làm điều đó như thế này:

iterable = "BINGO"    
" ".join(iterable)
> 'B I N G O'

Nhưng hãy nhớ rằng đối số là một điều có được, giống như một chuỗi, danh sách, tuple. Mặc dù phương thức trả về một chuỗi.

iterable = ['B', 'I', 'N', 'G', 'O']    
" ".join(iterable)
> 'B I N G O'

Điều gì xảy ra nếu bạn sử dụng dấu gạch nối như một chuỗi?

iterable = ['B', 'I', 'N', 'G', 'O']    
"-".join(iterable)
> 'B-I-N-G-O'

Phương pháp số 3: Sử dụng phương thức thay thế ().

Khi bạn tìm thấy một ký tự số trong chuỗi, hãy thay thế ký tự đó bằng không gian được thêm vào bên trái và phải.

iterable = "BINGO"
separator = " " # A whitespace character.
                # The string to which the method will be applied
separator.join(iterable)
> 'B I N G O'

3

iterable = "BINGO"
separator = " " # A whitespace character.
                # The string to which the method will be applied
separator.join(iterable)
> 'B I N G O'
