Những gì được đặt theo nghĩa đen

SETIS Bộ sưu tập của bộ dữ liệu chưa được đặt hàng. Nó được bao quanh bởi {} và mỗi phần tử được phân tách bằng dấu phẩy (,).

Ví dụ: Chúng ta có thể tạo một tập hợp các nguyên âm và trái cây. & NBSP;

Các

>>> a = 'A string'  # string literal with single quotes
>>> b = "A string"  # string literal with double quotes
>>> b == a  # there is no difference between these strings
True

>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash
81
>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash
1
>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash
36
>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash
84___

>>> print('Single quoted string with " is no problem')
Single quoted string with " is no problem

Đặc biệt theo nghĩa đen là gì

>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash

Python chứa một nghĩa đen đặc biệt (không có). Không có ai được sử dụng để xác định một biến null. Nếu không có ai được so sánh với bất cứ điều gì khác ngoài ‘không có, thì nó sẽ trả về sai.

>>> print("Double quoted string with ' is no problem")
Double quoted string with ' is no problem
>>> print("Double quoted string containing \" is OK with backslash")
Double quoted string containing " is OK with backslash

>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash
94
>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash
1
>>> print('Single quoted string containing \' is OK with backslash')
Single quoted string containing ' is OK with backslash
96

>>> print('Backslash before "n", as in \n, inserts a new line character')  #doctest: +NORMALIZE_WHITESPACE
Backslash before "n", as in
, inserts a new line character

Nếu bạn không muốn dấu gạch chéo ngược có ý nghĩa đặc biệt này, hãy đặt tiền tố theo nghĩa đen của bạn với ‘R, có nghĩa là Raw Raw:

>>> print(r'Prefixed by "r" the \n no longer inserts a new line')
Prefixed by "r" the \n no longer inserts a new line

Bạn có thể sử dụng trích dẫn ba để kèm theo các chuỗi có nhiều hơn một dòng:

>>> print('''This string literal
... has more than one
... line''')
This string literal
has more than one
line

Báo giá ba có thể sử dụng dấu ngoặc kép đơn hoặc kép:

>>> print("""This string literal
... also has more than one
... line""")
This string literal
also has more than one
line

Nói chung, nghĩa đen là một ký hiệu để thể hiện một giá trị cố định trong mã nguồn. Chúng cũng có thể được định nghĩa là giá trị thô hoặc dữ liệu được đưa ra trong các biến hoặc hằng số. Python có các loại nghĩa đen khác nhau như:

  1. Chuỗi chữ
  2. Chữ số
  3. Boolean Biết chữ
  4. Bộ sưu tập theo nghĩa đen
  5. Văn học đặc biệt

Chuỗi chữ là gì

Một chuỗi theo nghĩa đen có thể được tạo bằng cách viết một văn bản (một nhóm các ký tự) được bao quanh bởi một câu nói đơn (), gấp đôi (phạm vi) hoặc ba trích dẫn. & nbsp; bằng cách sử dụng trích dẫn ba, chúng tôi có thể viết các chuỗi nhiều dòng hoặc hiển thị chúng theo cách mong muốn. & NBSP;

Ví dụ: Ở đây Geekforgeeks là một chuỗi theo nghĩa đen được gán cho một biến (s). & Nbsp;Here geekforgeeks is a string literal that is assigned to a variable(s).

Cả số dương và số âm bao gồm 0. Không nên có bất kỳ phần phân số nào.

Chúng tôi đã chỉ định các chữ số nguyên (0B10100, 50, 0O320, 0x12B) cho các biến khác nhau. Ở đây, ‘A‘ là một nghĩa đen nhị phân, ‘B, là một hình chữ thập,‘ C ‘là một nghĩa đen, và‘ D là một nghĩa đen của hình lục giác. Nhưng khi sử dụng hàm in để hiển thị giá trị hoặc để có được đầu ra, chúng đã được chuyển đổi thành thập phân.
