Help users to dynamically manage python package resources and bid farewell to the constraints of the requirements.txt file.

Build-in pip

Dynamic-Pip

Through DynamicPip class object, dynamically manage (install, delete, etc.) python packages during the execution of the program. In addition, compared to build-in pip, dynamic-pip also supports some extended functions.

Example: Install the numpy package at runtime

from dynamicPip import DynamicPip

dynamic_pip = DynamicPip()

# declare target package
target_package = 'numpy==1.21.6'

# install
print(f'----- install {target_package} test -----')
rtn = dynamic_pip.install_single_package(target_package)
print(f'return result code {rtn}\n')

# check package list
print(f'----- list {target_package} test -----')
rtn = DynamicPip.list_package()
print(f'return result {rtn}\n')

# uninstall single package
print(f'----- uninstall {target_package} test -----')
rtn = DynamicPip.remove_single_package(target_package)
print(f'return result code {rtn}\n')

del dynamic_pip

Example: Build a requirement map

from dynamicPip import DynamicPip

dynamic_pip = DynamicPip()

dynamic_pip.generate_requires_map()

Example: List all installed packages. (pip list)

# check package as dict. (key = package name, value = version )
rtn = dynamic_pip.list_package()
print(f'return result {rtn}\n')

Example: Generate a requirement map

dynamic_pip.generate_requires_map(target_output_requirements__map_file_name)

Features

• support install / uninstall specific package(s) at runtime
• install / uninstall from the given requirements file
• support python test unit
• support multiple index-url, auto-detect fastest PyPI mirror
• support extra-index-url
• export requirements file
• build requires map

Limitations

• official inspect function is still in the experimental stage.
• official --dry-run function is still in the experimental stage.
• official --report function is still in the experimental stage.

Future version

• generate a report about all installed packages
• find package exist
• auto-detect packages with custom version from github
• verify hash
• install from local file
• install from compressed file
• install from FTP
• dynamic import
