ContextManaged Assign

This Python project provides a context manager for temporarily assigning a value to a variable or attribute. The original value is restored when the context is exited.

Usage

from contextmanaged_assign import assign

l = [1, 2, 3]

assert l[0] == 1
with assign("l[0]", 2):
    assert l[0] == 2
assert l[0] == 1

Please note that assign cannot modify local variables themselves. For example, the following code will not work:

x = 1
with assign("x", 2):
    assert x == 2  # AssertionError: 1 != 2
assert x == 1

Installation

Simply install the package using pip:

pip install contextmanaged-assign

Then import the assign function from the contextmanaged-assign module.
