How do I import variable packages in Python like using variable variables ($$) in PHP?

by

Python doesn’t have a feature that’s directly equivalent to PHP’s “variable variables”. To get a “variable variable”‘s value (or the value of any other expression) you can use the eval function.

foo = "Hello World"
print eval("foo")

However, this can’t be used in an import statement.

It is possible to use the __import__ function to import using a variable.

package = "os"
name = "path"

imported = getattr(__import__(package, fromlist=[name]), name)

is equivalent to

from os import path as imported
