This example demonstrates a Python utility that splits a mixed Chinese-English string into its Chinese and English components, returning them as a tuple. It shows how the function identifies contiguous Chinese characters (including punctuation and spaces) from either the start or end of the input, then isolates the remaining text as the English portion. The code relies on the `re` module’s compiled patterns to match Chinese ranges (`\u4e00-\u9fa5`) and an English punctuation set, with fallback logic to handle cases where the Chinese segment is too short. The implementation includes configurable thresholds for minimum lengths of both extracted parts.

[中文标点转英文] #string

This example demonstrates a Python utility that converts Chinese punctuation marks into their English equivalents in a given string. The function `punc_chinese2english` builds translation tables using the built-in `str.maketrans` method, mapping a set of characters such as full-width commas, periods, and quotation marks to standard ASCII punctuation. It applies this mapping via the string `translate` method, returning the converted text. The code explicitly lists the Chinese and English punctuation pairs, making the transformation rule clear and easy to modify.

[Java判断字符是否是汉字]汉字判断 #java #character util

This example demonstrates a Java utility for determining whether a character or string contains Chinese characters. The code defines a `CharacterUtils` class with two static methods: `isChinese(char)` checks a single character by comparing its Unicode value against the CJK Unified Ideographs block (0x4E00–0x9FA5), while `isChineseStr(String)` iterates through each character of a string using `toCharArray()` and returns `true` if any character qualifies. The logic relies on direct integer range comparisons on the primitive `char` type, with no external libraries or data sources involved. The implementation is straightforward and self-contained, suitable for text-processing tasks.

[print_unicode] python2 下在命令行中正常打印嵌套在 dict/list 内的 unicode 字符 #python #string

This example shows a Python 2 utility function that makes nested Unicode characters inside dictionaries and lists print correctly to the command line. The function `print_uni` takes any string `s`, applies `repr` to capture its escaped form, and then decodes that representation using `"unicode-escape"` to reveal the actual Unicode glyphs. It relies on the built-in `repr` function and the string `decode` method, demonstrating a workaround for Python 2’s default ASCII-based printing of container structures. The code is a standalone snippet from a gist by Shawn91, focusing on a common debugging pain point.

[split pandas cell into rows]将一个包含字符串或 list 的 cell，使用特定字符，将 cell 分成多行，同行其他 cells 复制值 #pandas

This example shows a pandas data-wrangling technique that transforms a DataFrame by splitting a single cell containing a delimited string or list into multiple rows while duplicating the other column values across the new rows. The function `splitDataFrameList` accepts a DataFrame, the target column name, and a separator string, then uses `df.apply` along the rows and a helper function to parse each cell. It relies on the `collections.Iterable` check and the `str.split` method to separate values, ultimately constructing a new DataFrame from the accumulated row dictionaries via `pd.DataFrame`.

[注音符号字母转换] #string

This example demonstrates how to normalize Unicode text that contains accented or composite characters into plain ASCII, showing the transformation before and after processing. It uses Python’s `unicodedata` module, specifically the `normalize` function with `NFKD` and `NFD` forms, followed by encoding to ASCII with the `'ignore'` error handler, or by using a dictionary of combining characters with `translate` to strip diacritical marks. The code includes two methods: one that removes non-ASCII characters entirely, and another that preserves them while eliminating accent marks, with comments explaining the behavior for both Python 2 and 3.

[check_string_contain_relation]给定 a list of strings，检查哪些字符串元素是其他字符串元素的 substring #string

This example demonstrates a string containment check: given a list of strings, it identifies which elements are substrings of other elements in the list. The code first joins all strings using a separator and then uses recursive string searching to count occurrences. It leverages Python’s built-in `str.find` method within a custom recursive function, `_appear_at_least_n_times`, to efficiently stop searching after finding the required number of matches. The final output is a filtered list containing only those strings that appear at least twice in the combined text, as shown by the example returning `['产科']` for the input `['妇产科', '产科', '儿科']`.

A `.split()` function for excel—assumes 0 index, "-" delimiter, and reference cell "A2" but are all customizable. Outputs a string representation of the formula

This example generates spreadsheet formulas that split text from a reference cell into separate parts. It shows a Python function that recursively builds nested Excel-style `SEARCH`, `LEFT`, and `MID` calls. The code defines `build(i, delimiter='"-"', reference_cell="A2")`, which assumes a zero-based index and a hyphen delimiter, but all parameters are customizable. The output is a string representation of the formula, constructed through the helper `recurse` to incrementally locate delimiter positions. It does not execute or render the formula; it only produces the textual formula string.

[百度百科简介内容解析] #爬虫

This example parses the summary table from Baidu Baike encyclopedia pages to extract short names, abbreviations, and foreign-company division names. It uses the BeautifulSoup library to locate the HTML element with class `basic-info cmn-clearfix`, then a helper function `get_baike_shorten_names` finds a definition term (like `dt` for “英文名”) and retrieves its sibling `dd` value, cleaning out bracketed reference numbers with a regular expression. The code demonstrates a reusable scraping pattern for structured infobox data from Baidu Baike, returning the cleaned text or an empty string when no match is found.
