The numpy library is a Python library for scientific computing that provides a large number of numerical calculations and array operation functions. The following are some commonly used numpy functions:
1. Create an array:
numpy.array: Create a numpy array.
numpy.zeros: Create an array of all zeros.
numpy.ones: Create an array of all ones.
numpy.arange: Create an array that increases by a specified step size.
numpy.linspace: Create an array evenly distributed within the specified range.
2. Array operations:
numpy.shape: Returns the dimensions of the array.
numpy.reshape: Change the shape of the array.
numpy.transpose: Swap the dimensions of the array.
numpy.concatenate: Concatenate arrays along the specified axis.
numpy.split: Split an array into multiple subarrays.
3. Mathematical operations:
numpy.add: Add array elements.
numpy.subtract: Subtract array elements.
numpy.multiply: Multiply array elements.
numpy.divide: Perform division operation on array elements.
numpy.power: Exponentiates array elements.
4. Statistical function:
numpy.mean: Calculate the average of the array.
numpy.median: Calculate the median of an array.
numpy.std: Calculate the standard deviation of an array.
numpy.min: Returns the minimum value of the array.
numpy.max: Returns the maximum value of the array.
5. Array indexing and slicing:
numpy.argmax: Returns the index of the maximum value in the array.
numpy.argmin: Returns the index of the minimum value in the array.
numpy.where: Returns the index of the array element that satisfies the condition based on the specified condition.
numpy.take: Take out array elements according to the specified index.
This is just a small part of the commonly used functions in the numpy library. numpy also provides many other powerful functions and methods. You can consult numpy official documentation or other tutorials to learn more about how to use functions based on your specific needs.

Python and C each have their own advantages, and the choice should be based on project requirements. 1) Python is suitable for rapid development and data processing due to its concise syntax and dynamic typing. 2)C is suitable for high performance and system programming due to its static typing and manual memory management.

Choosing Python or C depends on project requirements: 1) If you need rapid development, data processing and prototype design, choose Python; 2) If you need high performance, low latency and close hardware control, choose C.

By investing 2 hours of Python learning every day, you can effectively improve your programming skills. 1. Learn new knowledge: read documents or watch tutorials. 2. Practice: Write code and complete exercises. 3. Review: Consolidate the content you have learned. 4. Project practice: Apply what you have learned in actual projects. Such a structured learning plan can help you systematically master Python and achieve career goals.

Methods to learn Python efficiently within two hours include: 1. Review the basic knowledge and ensure that you are familiar with Python installation and basic syntax; 2. Understand the core concepts of Python, such as variables, lists, functions, etc.; 3. Master basic and advanced usage by using examples; 4. Learn common errors and debugging techniques; 5. Apply performance optimization and best practices, such as using list comprehensions and following the PEP8 style guide.

Python is suitable for beginners and data science, and C is suitable for system programming and game development. 1. Python is simple and easy to use, suitable for data science and web development. 2.C provides high performance and control, suitable for game development and system programming. The choice should be based on project needs and personal interests.

Python is more suitable for data science and rapid development, while C is more suitable for high performance and system programming. 1. Python syntax is concise and easy to learn, suitable for data processing and scientific computing. 2.C has complex syntax but excellent performance and is often used in game development and system programming.

It is feasible to invest two hours a day to learn Python. 1. Learn new knowledge: Learn new concepts in one hour, such as lists and dictionaries. 2. Practice and exercises: Use one hour to perform programming exercises, such as writing small programs. Through reasonable planning and perseverance, you can master the core concepts of Python in a short time.

Python is easier to learn and use, while C is more powerful but complex. 1. Python syntax is concise and suitable for beginners. Dynamic typing and automatic memory management make it easy to use, but may cause runtime errors. 2.C provides low-level control and advanced features, suitable for high-performance applications, but has a high learning threshold and requires manual memory and type safety management.
