Blocking Imports

There are two ways to configure how imports are blocked or allowed.

• allowed_imports - Takes a list of module names. If this option is set, only imports in this list can be imported

• blocked_imports - Takes a list of module names. If this option is set, all inputs specified are blocked. If allowed_imports is set, blocked_imports will be ignored.

Example of using allowed_imports:

ipython_config.py

# In ipython_config.py
c = get_config()
c.ExamKernel.allowed_imports = ["math", "random"]

Example of trying to import a module that is not in the allowed imports

import os
---------------------------------------------------------------------------
ModuleNotFoundError: No module named os or os blocked by kernel.
Allowed imports are: [math, random]

Example of using blocked_imports:

ipython_config.py

# In ipython_config.py
c = get_config()
c.ExamKernel.blocked_imports = ["os", "pandas"]

Example of trying to import a module that is in the blocked imports

import os
---------------------------------------------------------------------------
ModuleNotFoundError: No module named os or os blocked by kernel.
The following imports are blocked: [os, pandas]
