Use pyinstaller for packaging

pyinstaller can package python programs into binary files. The packaged files are in an environment without python It can also be executed (but there must be relevant underlying libc related so files). pyinstaller supports packaging python programs into a single file. All it does is convert text into binary, which does not speed up python. On the contrary, it will affect the running speed of the packaged program.

Install pyinstaller

Install through pip:

pip install pyinstaller

Install through source code:

python setup.py install

Packaging program

Add the -F parameter. Package the program into a separate file:

pyinstaller -F test1.py

Use virtualenv packaging

virtualenv is used to create an "isolated" Python running environment for an application. Using virtualenv to manage python applications can avoid problems caused by library conflicts. Similarly, virtualenv cannot speed up Python. All it does is isolate the environment and make deployment more convenient.

Examples are as follows:

1. Install virtualenv

pip install virtualenv

2. Create a virtual environment

virtualenv -p /usr/bin/python2.6 py26env  --no-site-packages

3. Start the virtual environment

source py26env/bin/activate

4. Install the necessary python libraries

pip install …

5. After writing the code, start the program normally.

How can you perform mathematical operations on entire NumPy arrays efficiently?May 06, 2025 am 12:15 AM

Mathematical operations of the entire array in NumPy can be efficiently implemented through vectorized operations. 1) Use simple operators such as addition (arr 2) to perform operations on arrays. 2) NumPy uses the underlying C language library, which improves the computing speed. 3) You can perform complex operations such as multiplication, division, and exponents. 4) Pay attention to broadcast operations to ensure that the array shape is compatible. 5) Using NumPy functions such as np.sum() can significantly improve performance.

How do you insert elements into a Python array?May 06, 2025 am 12:14 AM

In Python, there are two main methods for inserting elements into a list: 1) Using the insert(index, value) method, you can insert elements at the specified index, but inserting at the beginning of a large list is inefficient; 2) Using the append(value) method, add elements at the end of the list, which is highly efficient. For large lists, it is recommended to use append() or consider using deque or NumPy arrays to optimize performance.
