assignment expression use case	Zachary Wilson	2022-09-01

Nicknamed the Walrus Operator for its resemblance to the face of a Walrus: :=, the [Assignment Expression][assignment_expression] allows one to assign a value to a variable if and only if it returns a result.

Since its inception, the [Assignment Expression][assignment_expression] has been a highly debated topic within the PSF.

# File Transfer for Pythonista
# ============================
# This script allows you to transfer Python files from
# and to Pythonista via local Wifi.
# It starts a basic HTTP server that you can access
# as a web page from your browser.
# When you upload a file that already exists, it is
# renamed automatically.
# From Pythonista's settings, you can add this script
# to the actions menu of the editor for quick access.
