Use the .equals() method to compare string content, because == only compare object references rather than content; 1. Use .equals() to compare string values equally; 2. Use .equalsIgnoreCase() to compare case ignoring; 3. Use .compareTo() to compare strings in dictionary order, returning 0, negative or positive numbers; 4. Use .compareToIgnoreCase() to compare case ignoring; 5. Use Objects.equals() or safe call method to process null strings to avoid null pointer exceptions. In short, you should avoid using == for string content comparisons unless it is explicitly necessary to check whether the object is in phase.

Using String.join() (Java8) is the easiest recommended method for connecting string arrays, just specify the separator directly; 2. For old versions of Java or when more control is needed, you can use StringBuilder to manually traverse and splice; 3. StringJoiner is suitable for scenarios that require more flexible formats such as prefixes and suffixes; 4. Using Arrays.stream() combined with Collectors.joining() is suitable for filtering or converting the array before joining; To sum up, if Java8 and above is used, the String.join() method should be preferred in most cases, which is concise and easy to read, but for complex logic, it is recommended.

Python's logging module can write logs to files through FileHandler. First, call the basicConfig configuration file processor and format, such as setting the level to INFO, using FileHandler to write app.log; secondly, add StreamHandler to achieve output to the console at the same time; Advanced scenarios can use TimedRotatingFileHandler to divide logs by time, for example, setting when='midnight' to generate new files every day and keep 7 days of backup, and make sure that the log directory exists; it is recommended to use getLogger(__name__) to create named loggers, and produce

Using PandasStyling in JupyterNotebook can achieve the beautiful display of DataFrame. 1. Use highlight_max and highlight_min to highlight the maximum value (green) and minimum value (red) of each column; 2. Add gradient background color (such as Blues or Reds) to the numeric column through background_gradient to visually display the data size; 3. Custom function color_score combined with applymap to set text colors for different fractional intervals (≥90 green, 80~89 orange, 60~79 red,

Computed has a cache, and multiple accesses are not recalculated when the dependency remains unchanged, while methods are executed every time they are called; 2.computed is suitable for calculations based on responsive data. Methods are suitable for scenarios where parameters are required or frequent calls but the result does not depend on responsive data; 3.computed supports getters and setters, which can realize two-way synchronization of data, but methods are not supported; 4. Summary: Use computed first to improve performance, and use methods when passing parameters, performing operations or avoiding cache, following the principle of "if you can use computed, you don't use methods".

TypeScript's advanced condition types implement logical judgment between types through TextendsU?X:Y syntax. Its core capabilities are reflected in the distributed condition types, infer type inference and the construction of complex type tools. 1. The conditional type is distributed in the bare type parameters and can automatically split the joint type, such as ToArray to obtain string[]|number[]. 2. Use distribution to build filtering and extraction tools: Exclude excludes types through TextendsU?never:T, Extract extracts commonalities through TextendsU?T:Never, and NonNullable filters null/undefined. 3
