Python strings, lists, tuples, sets and dictionaries
Strings, lists, tuples, sets and dictionaries 1. String (str) A string is a text data type in Python, it is an immutable sequence of zero or more characters. String literals can be enclosed in single quotes, double quotes, or triple quotes, or special characters can be entered using backslash \ escape characters. str1 = ‘Hello, […]

Python containers–strings, lists, tuples, dictionaries
String Function: Used to store descriptive data String – Definition # 1. Single quote ‘abc’ # 2. Double quotes ‘abc’ # 3. Triple quotes ‘abc’ str1 = ‘string1’ str2 = “string2” str3 = “””First line second line The third row “”” print(str1) print(str2) print(str3) String – subscript (index) Strings in python can correspond to character […]
18 | Compile-time tips for using variable templates and tuples
Today we will talk about a special topic, how to use variable templates and tuples to complete some common functions, especially compile-time calculations. Variable template Variable templates are a new feature introduced in C++11 that allow us to express an indefinite number and type of parameters in template parameters. From a practical perspective, it has […]
Python data containers – tuples and strings
1. Data container-tuple 1. Definition of tuple (1) Empty tuple: tuple name = () or tuple name = tuple() (2) Non-empty tuple: Tuple name = (element 1, element 2, element 3,…) When there is only one element, a comma is required: tuple name = (element 1,) # Define empty tuple tuple1 = () print(tuple1, type(tuple1)) […]

Exploring use cases for TypeScript tuples
Tuples extend the functionality of the array data type. Using tuples, we can easily construct special types of arrays where elements are of a fixed type relative to index or position. Due to the nature of TypeScript, these element types are known at initialization time. Using tuples, we can define the type of data that […]
Lists, Tuples, Dictionaries and Sorting in Python
Python list Sequences are the most basic data structure in Python. Each value in the sequence has a corresponding position value, called an index, where the first index is 0, the second is 1, and so on. Python has 6 built-in types for sequences, but the most common are lists and tuples. Operations that can […]
