Step1 执行多维度数据清洗与条件筛选，包含列名自动识别、RGB 颜色过滤、前缀匹配及正则提取。
# 1. 自动识别同义列名并筛选非空值
target_cols = ['域名', '缩写', 'code', 'domain']
for col in target_cols:
if col in df.columns:
df = df[df[col].notna()]
break
# 2. 基于数值通道的精确筛选（如 RGB 颜色过滤）
# 技巧：多条件组合筛选时使用 & 符号
if all(c in df.columns for c in ['Red', 'Green', 'Blue']):
df = df[(df['Red'] == 0) & (df['Green'] == 0) & (df['Blue'] == 0)]
# 3. 基于字符串前缀筛选并进行数值转换计算
if '编号' in df.columns:
# 筛选特定前缀的项目
df = df[df['编号'].astype(str).str.startswith('TXL3')]
# 技巧：使用 errors='coerce' 处理无法转换的脏数据
df['val_a'] = pd.to_numeric(df['技工'], errors='coerce')
df['val_b'] = pd.to_numeric(df['普工'], errors='coerce')
df['total_val'] = df['val_a'] + df['val_b']
avg_val = df['total_val'].mean()
# 4. 基于特定分类值的筛选与统计
if '钢筋级别' in df.columns:
sub_df = df[df['钢筋级别'] == 'Ⅱ'].copy()
sub_df['target_val'] = pd.to_numeric(sub_df['屈服荷载'], errors='coerce')
avg_target = sub_df['target_val'].mean()
# 5. 正则表达式匹配提取特定字段
if '命令' in df.columns:
pattern = r'--pct-'
matched_df = df[df['命令'].astype(str).str.contains(pattern, na=False)]
# 提取关键列保留追溯性
extracted_data = matched_df[['NO', '命令', '说明']].copy()
Step2 将处理结果保存至 Excel，并对输出文件进行样式美化（如全行标红），最后生成下载链接。
from openpyxl.styles import PatternFill
output_path = "filtered_result.xlsx"
with pd.ExcelWriter(output_path, engine='openpyxl') as writer:
if 'total_val' in df.columns:
df.to_excel(writer, sheet_name='统计结果', index=False)
if 'extracted_data' in locals():
extracted_data.to_excel(writer, sheet_name='正则提取', index=False)
# 技巧：使用 openpyxl 进行后期样式加工，突出显示关键结果
wb = openpyxl.load_workbook(output_path)
red_fill = PatternFill(start_color='FFFF0000', end_color='FFFF0000', fill_type='solid')
for sheet_name in wb.sheetnames:
ws = wb[sheet_name]
for row in ws.iter_rows(min_row=2): # 跳过表头
for cell in row:
cell.fill = red_fill
wb.save(output_path)
# 输出标准下载链接格式
print(f"[下载结果文件](sandbox:{output_path})")

Integration with protocols.io API for managing scientific protocols. This skill should be used when working with protocols.io to search, create, update, or publish protocols; manage protocol steps and materials; handle discussions and comments; organize workspaces; upload and manage files; or integrate protocols.io functionality into workflows. Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
