# `paste.util.import_string` – Import objects from strings

‘imports’ a string – converts a string to a Python object, importing any necessary modules and evaluating the expression. Everything before the : in an import expression is the module path; everything after is an expression to be evaluated in the namespace of that module.

Alternately, if no : is present, then import the modules and get the attributes as necessary. Arbitrary expressions are not allowed in that case.

## Module Contents

`paste.util.import_string.` `eval_import`(s)

  Import a module, or import an object from a module.

  A module name like `foo.bar:baz()` can be used, where `foo.bar` is the module, and `baz()` is an expression evaluated in the context of that module. Note this is not safe on arbitrary strings because of the eval.

`paste.util.import_string.` `simple_import`(s)

  Import a module, or import an object from a module.

  A name like `foo.bar.baz` can be a module `foo.bar.baz` or a module `foo.bar` with an object `baz` in it, or a module `foo` with an object `bar` with an attribute `baz`.

`paste.util.import_string.` `import_module`(s)

  Import a module.

`paste.util.import_string.` `try_import_module`(module_name)

  Imports a module, but catches import errors. Only catches errors when that module doesn’t exist; if that module itself has an import error it will still get raised. Returns None if the module doesn’t exist.
