Python如何将列表字符串首个冒号前内容设为粗体、后续内容正常显示

实现代码 #

import os
# Windows系统需要加这行开启ANSI转义码支持，非Windows系统可删除
os.system('')

class style:
    BOLD = "\033[1m"
    END = "\033[0m"

def Convert(string):
    li = list(string.split("\n\n"))
    return li

vocablist = ('''to remind s.o. (of sth./to do sth.): to put in mind of something: cause to remember

# 拆分得到词条列表
item_list = Convert(vocablist)
processed_list = []

for item in item_list:
    if ':' in item:
        # 仅拆分第一个冒号，分割为前后两部分，避免释义中的冒号影响结果
        key, value = item.split(':', 1)
        processed_item = f"{style.BOLD}{key}{style.END}:{value}"
    else:
        # 无冒号的词条直接保留原内容
        processed_item = item
    processed_list.append(processed_item)
    # 直接打印即可看到粗体效果
    print(processed_item)

逻辑说明 #

• split(':', 1)的第二个参数指定最大拆分次数为1，只会识别字符串里第一个出现的冒号做分割，完全符合你只加粗第一个冒号前内容的需求
• 修正了原有代码中直接遍历原始字符串、列表append方法使用错误、索引逻辑错误的问题
• 处理后的词条全部存储在processed_list中，可按需后续调用
