🧪 Core Code

import numpy as np

array_1 = np.array([10, 20, 30, 40, 50])
print("Original Array:", array_1)

print("Shape:", array_1.shape)
print("Size:", array_1.size)

print("Sliced Array:", array_1[1:4])

reshaped_array = array_1.reshape(5, 1)
print("\nReshaped Array (5x1):\n", reshaped_array)

multiplied_array = array_1 * 2
print("\nArray after Multiplying by 2:", multiplied_array)

filtered_array = array_1[array_1 > 25]
print("\nValues greater than 25:", filtered_array)

🧾 Output Summary

Original Array: [10 20 30 40 50]
Shape: (5,)
Size: 5
Sliced Array: [20 30 40]
Reshaped Array (5x1):
 [[10]
 [20]
 [30]
 [40]
 [50]]
Array after Multiplying by 2: [20 40 60 80 100]
Values greater than 25: [30 40 50]

🧩 Advanced Python Techniques Demonstrated

• Vectorized computation
• Efficient memory usage
• Conditional filtering
• Data restructuring for ML
• Clean output formatting

---

💼 Business Value Demonstrated

✔ Faster computation than Excel-like operations
✔ Reliable filtered data for business decisions
✔ Smooth integration with ML pipelines
✔ Supports cost-efficient analytics workflows

---

🔍 Key Observations:

• Array indexing & slicing se hum specific range ke values nikal sakte hain
• Reshaping se 1D array ko matrix form me convert karna easy hai
• Vectorized operations har element par one-shot me apply ho jate hain
• Boolean filter se sirf condition-match hone wale elements milte hain

---

🧩 Findings & Insights

• ⚡ Vectorization > Loops for numerical operations – faster & cleaner code
• 📐 Arrays ko easily reshape kiya ja sakta hai according to model/input needs
• 🧹 Boolean filtering se data cleaning & subsetting bahut asaan ho jata hai
• 📊 Yehi concepts aage chal kar Pandas, ML models & data pipelines me use hote hain
