Although distinct and distinct are related to distinction, they are used differently: distinct (adjective) describes the uniqueness of things themselves and is used to emphasize differences between things; distinct (verb) represents the distinction behavior or ability, and is used to describe the discrimination process. In programming, distinct is often used to represent the uniqueness of elements in a set, such as deduplication operations; distinct is reflected in the design of algorithms or functions, such as distinguishing odd and even numbers. When optimizing, the distinct operation should select the appropriate algorithm and data structure, while the distinct operation should optimize the distinction between logical efficiency and pay attention to writing clear and readable code.
Distinguish distinct
and distinguish
: nuances and code practices
You ask what is the relationship between distinct
and distinguish
? They are indeed closely related to distinction and identification, but their usage and focus are slightly different. Understanding this subtle difference will allow you to express your meaning more accurately in programming and writing.
This article will explore the meaning of these two words in depth and combine code examples to show their application in actual programming, as well as some potential pitfalls and optimization strategies. After reading, you will be able to choose the right words more confidently and write more efficient and readable code.
Basic knowledge review:
Both of these words are derived from the Latin roots and are related to "distinguishing". But distinct
emphasizes the uniqueness and difference of things themselves , which is a static description; while distinguish
emphasizes the distinction between behavior or ability , which is a dynamic process.
Core concept analysis:
distinct
is usually used as an adjective, meaning "unique", "different", and "clear". For example, "These are two distinct problems." means that the two problems are very different. In programming, it is often used to represent the uniqueness of elements in a collection, such as the DISTINCT
keyword in a database query, to remove duplicate results.
distinguish
is usually used as a verb, indicating "distinguish", "distinguish", and "identify". For example, "Can you distinguish between these two sounds?" means whether you can distinguish between these two sounds. In programming, it is often reflected in the design of algorithms or functions, such as image recognition algorithms that need to distinguish different objects.
Code example:
Let's use Python to demonstrate the manifestation of these two words in programming.
Application of distinct
:
Suppose we have a list of duplicate elements:
<code class="python">my_list = [1, 2, 2, 3, 4, 4, 5]</code>
We can use the collection to remove duplicate elements, thus obtaining a new list containing distinct
elements:
<code class="python">distinct_list = list(set(my_list)) # 利用集合的特性去除重復(fù)元素print(distinct_list) # 輸出: [1, 2, 3, 4, 5]</code>
Here set()
function implicitly uses the concept of distinct
, which only retains unique elements.
distinguish
application:
Now, let's write a function to distinguish odd and even numbers:
<code class="python">def distinguish_even_odd(number): """區(qū)分奇數(shù)和偶數(shù)""" if number % 2 == 0: return "even" else: return "odd" print(distinguish_even_odd(4)) # 輸出: even print(distinguish_even_odd(7)) # 輸出: odd</code>
This function implements the function of distinguish
, which distinguishes according to the characteristics of the input numbers and returns different results.
Advanced usage and potential problems:
When working with large data sets, directly using set()
to remove duplicate elements may consume a lot of memory, especially when the number of elements is huge and the elements themselves are relatively complex. At this time, more advanced algorithms need to be considered, such as using hash tables or sorting methods to improve efficiency.
Similarly, the efficiency of the distinguish
function also depends on the specific distinction logic. If the distinction is complex, optimization algorithms are needed to improve performance, such as using more efficient judgment conditions or data structures.
Performance optimization and best practices:
For distinct
operations, it is crucial to choose the right data structure. If the data volume is not large, sets are a good choice; but for large data sets, consider using more memory-saving algorithms such as bitmaps or hash tables.
For distinguish
operations, the algorithm needs to be carefully designed, the appropriate data structures and algorithms are selected, and performance tests are performed to ensure its efficiency and stability. Writing clear and readable code and adding sufficient comments can effectively improve the maintainability and understanding of the code.
In short, although distinct
and distinguish
are related in meanings, there are subtle differences in specific applications. Only by understanding these differences and selecting appropriate methods and data structures based on actual conditions can we write efficient and reliable code. Remember, programming is not only a problem-solving, but also an embodiment of art. Only by striving for excellence can you write elegant code.

The key to dealing with API authentication is to understand and use the authentication method correctly. 1. APIKey is the simplest authentication method, usually placed in the request header or URL parameters; 2. BasicAuth uses username and password for Base64 encoding transmission, which is suitable for internal systems; 3. OAuth2 needs to obtain the token first through client_id and client_secret, and then bring the BearerToken in the request header; 4. In order to deal with the token expiration, the token management class can be encapsulated and automatically refreshed the token; in short, selecting the appropriate method according to the document and safely storing the key information is the key.

To test the API, you need to use Python's Requests library. The steps are to install the library, send requests, verify responses, set timeouts and retry. First, install the library through pipinstallrequests; then use requests.get() or requests.post() and other methods to send GET or POST requests; then check response.status_code and response.json() to ensure that the return result is in compliance with expectations; finally, add timeout parameters to set the timeout time, and combine the retrying library to achieve automatic retry to enhance stability.

In Python, variables defined inside a function are local variables and are only valid within the function; externally defined are global variables that can be read anywhere. 1. Local variables are destroyed as the function is executed; 2. The function can access global variables but cannot be modified directly, so the global keyword is required; 3. If you want to modify outer function variables in nested functions, you need to use the nonlocal keyword; 4. Variables with the same name do not affect each other in different scopes; 5. Global must be declared when modifying global variables, otherwise UnboundLocalError error will be raised. Understanding these rules helps avoid bugs and write more reliable functions.

How to efficiently handle large JSON files in Python? 1. Use the ijson library to stream and avoid memory overflow through item-by-item parsing; 2. If it is in JSONLines format, you can read it line by line and process it with json.loads(); 3. Or split the large file into small pieces and then process it separately. These methods effectively solve the memory limitation problem and are suitable for different scenarios.

In Python, the method of traversing tuples with for loops includes directly iterating over elements, getting indexes and elements at the same time, and processing nested tuples. 1. Use the for loop directly to access each element in sequence without managing the index; 2. Use enumerate() to get the index and value at the same time. The default index is 0, and the start parameter can also be specified; 3. Nested tuples can be unpacked in the loop, but it is necessary to ensure that the subtuple structure is consistent, otherwise an unpacking error will be raised; in addition, the tuple is immutable and the content cannot be modified in the loop. Unwanted values can be ignored by \_. It is recommended to check whether the tuple is empty before traversing to avoid errors.

Python implements asynchronous API calls with async/await with aiohttp. Use async to define coroutine functions and execute them through asyncio.run driver, for example: asyncdeffetch_data(): awaitasyncio.sleep(1); initiate asynchronous HTTP requests through aiohttp, and use asyncwith to create ClientSession and await response result; use asyncio.gather to package the task list; precautions include: avoiding blocking operations, not mixing synchronization code, and Jupyter needs to handle event loops specially. Master eventl

Pure functions in Python refer to functions that always return the same output with no side effects given the same input. Its characteristics include: 1. Determinism, that is, the same input always produces the same output; 2. No side effects, that is, no external variables, no input data, and no interaction with the outside world. For example, defadd(a,b):returna b is a pure function because no matter how many times add(2,3) is called, it always returns 5 without changing other content in the program. In contrast, functions that modify global variables or change input parameters are non-pure functions. The advantages of pure functions are: easier to test, more suitable for concurrent execution, cache results to improve performance, and can be well matched with functional programming tools such as map() and filter().

ifelse is the infrastructure used in Python for conditional judgment, and different code blocks are executed through the authenticity of the condition. It supports the use of elif to add branches when multi-condition judgment, and indentation is the syntax key; if num=15, the program outputs "this number is greater than 10"; if the assignment logic is required, ternary operators such as status="adult"ifage>=18else"minor" can be used. 1. Ifelse selects the execution path according to the true or false conditions; 2. Elif can add multiple condition branches; 3. Indentation determines the code's ownership, errors will lead to exceptions; 4. The ternary operator is suitable for simple assignment scenarios.
