Try This NumPy Example
import numpy as np # Create arrays arr = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) matrix = np.array([[1, 2, 3], [4, 5, 6], [7, 8, 9]]) print("Array:", arr) print("Matrix:\n", matrix) print("\nArray Statistics:") print(f" Mean: {arr.mean():.2f}") print(f" Std Dev: {arr.std():.2f}") print(f" Sum: {arr.sum()}") print("\nMatrix Operations:") print(f" Shape: {matrix.shape}") print(f" Transpose:\n{matrix.T}") # Linear algebra a = np.array([[2, 1], [5, 3]]) b = np.array([8, 13]) solution = np.linalg.solve(a, b) print(f"\nSolving linear system Ax = b:") print(f" x = {solution}")
What You Can Do With NumPy Online
Array & Matrix Operations
Create N-dimensional arrays, reshape matrices, compute dot products, and perform element-wise operations — all with pure NumPy syntax.
Linear Algebra & Statistics
Run np.linalg.solve(), np.dot(), np.mean(), np.std(), and more. Perfect for data science assignments, ML prep, and numerical computing.
Zero Setup, Full Library
NumPy, pandas, and Matplotlib are pre-installed in the browser runtime. Open the editor and import numpy as np immediately.
How to Run NumPy Arrays Online
Our free online NumPy compiler provides a full scientific computing environment directly in your browser. Whether you are practicing for a data science interview or calculating complex algorithms, here is how to start:
- Import NumPy: Begin your script with the standard import convention:
import numpy as np. - Create Arrays: Replace slow Python lists with fast, typed multidimensional arrays using
np.array([1, 2, 3]). - Perform Matrix Operations: You can effortlessly slice data, reshape matrices, or run mathematical operations like
np.dot()andnp.linalg.solve(). - Analyze Results: Print your arrays straight to the console. The output panel instantly displays the processed numerical data without requiring server-side execution.
To explore all available mathematical functions, random number generators, and Fourier transforms, visit the official NumPy documentation.
Frequently Asked Questions
Can I run NumPy online without installing Python?
Yes. PythonHere runs Python in your browser via WebAssembly (Pyodide). NumPy is pre-loaded — just import numpy as np and run.
Does it support matrix operations and linear algebra?
Yes. All core NumPy functionality works: array creation, slicing, reshaping, np.linalg, np.fft, random number generation, and more.
Is it free?
100% free, forever. No account required, no time limit, no credit card.
Can I use pandas alongside NumPy?
Yes. Both pandas and NumPy are available simultaneously. Use them together as you would in a local environment.
