+# Importing Scientific Data using Pandas
+
+^8eb966
+
+[Introduction text]
+
+
+Pandas is a library that is built on top of NumPy and is there for customarily to import both when working with Pandas.
+
+```python
+import numpy as np
+import pandas as pd
+```
+
+
+DataFrame
+
+A `DataFrame` in pandas is a two-dimensional data structure like table with rows and columns.
+
+
+
+```python
+# Tensile test data
+data = {
+    "Force (N)": [10, 15, 20, 25],
+    "Displacement (mm)": [1.2, 1.8, 2.5, 3.0],
+    "Stress (MPa)": [2.6, 3.9, 5.2, 6.5],
+}
+```
+
+
+
+Object Creation
+
+```python
+# Create DataFrame with row labels
+df = pd.DataFrame(data, index=["Test1", "Test2", "Test3", "Test4"])
+
+print(df)
+```
