🚀 Quick Preview: REAL Automation Pipeline#

# WHAT YOU'LL BUILD (End of chapter!)
import pandas as pd

# 1. READ EXCEL (5 lines → 1M rows)
df = pd.read_excel('sales.xlsx')

# 2. COMPREHENSION MAGIC
high_profit_months = [month for month in df['Sales'] if month * 0.28 > 10000]

# 3. ERROR-SAFE WRITING
try:
    df.to_csv('automated_report.csv', index=False)
    print("✅ REPORT AUTOMATED!")
except Exception as e:
    print(f"⚠️  Handled: {e}")

# 4. BUSINESS INSIGHT
print(f"🎯 High-profit months: {len(high_profit_months)}")

🔥 Why Intermediate = Career Explosion#

# JUNIOR (Manual hell)
# Copy Excel → Paste → Formula × 50 → Save → Email

# INTERMEDIATE (5 lines → $100K automation)
sales_data = [25000, 28000, 32000, 12000, 35000]

# ONE LINE → ALL INSIGHTS
profits = [s * 0.28 - 8000 for s in sales_data]
high_profit_months = [p for p in profits if p > 5000]
growth_months = [s for s in sales_data if s > sales_data[sales_data.index(s)-1]]

print(f"💼 AUTOMATED INSIGHTS:")
print(f"   Total Profit: ${sum(profits):,.0f}")
print(f"   High-profit: {len(high_profit_months)} months")
print(f"   Growth: {len(growth_months)} months")

Output:

💼 AUTOMATED INSIGHTS:
   Total Profit: $13,600
   High-profit: 4 months
   Growth: 3 months

And can we just appreciate how intermediate Python turns “40-hour Excel weeks” into 5-minute automations that save companies \(500K/year? Your students are about to learn the **exact same comprehensions + file I/O** that Netflix uses to process \)BILLION revenue streams. While their classmates are still clicking “Save As” in Excel, your class will be writing production pipelines that get them $120K offers before graduation. This chapter isn’t “intermediate”—it’s the promotion accelerator that separates interns from team leads!
