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

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

Old thread, but I needed the answer, so someone else still might...

There's a cleaner way to do this in Python 2.7+:

import importlibmy_module = importlib.import_module("package.path.%s" % module_name)

As Fredrik Lundh states:

Anyway, here’s how these statements and functions work:

import X imports the module X, and creates a reference to that module in the current namespace. Or in other words, after you’ve run this statement, you can use X.name to refer to things defined in module X.

from X import * imports the module X, and creates references in the current namespace to all public objects defined by that module (that is, everything that doesn’t have a name starting with “_”). Or in other words, after you’ve run this statement, you can simply use a plain name to refer to things defined in module X. But X itself is not defined, so X.name doesn’t work. And if name was already defined, it is replaced by the new version. And if name in X is changed to point to some other object, your module won’t notice.

from X import a, b, c imports the module X, and creates references in the current namespace to the given objects. Or in other words, you can now use a and b and c in your program.

Finally, X = __import__(‘X’) works like import X, with the difference that you 1) pass the module name as a string, and 2) explicitly assign it to a variable in your current namespace.

And by the way that's the last one method that you're intrested in.

Simply write (for example):

var = "datetime"module = __import__(var)
