newStringOrUnicode
```
public static PyString newStringOrUnicode(java.lang.String s)
```
Return a PyString for the given Java String, if it can be represented as US-ASCII, and a PyUnicode otherwise.

Parameters:

s - string content

Returns:

PyString or PyUnicode according to content of s.

newStringOrUnicode
```
public static PyString newStringOrUnicode(PyObject precedent,
                                          java.lang.String s)
```
Return a PyString for the given Java String, if it can be represented as US-ASCII and if a preceding object is not a PyUnicode, and a PyUnicode otherwise. In some contexts, we want the result to be a PyUnicode if some preceding result is a PyUnicode.

Parameters:

precedent - string of which the type sets a precedent

s - string content

Returns:

PyString or PyUnicode according to content of s.

newStringUTF8

public static PyString newStringUTF8(java.lang.String s)

fileSystemDecode
```
public static java.lang.String fileSystemDecode(PyString filename)
```
Return a file name or path as Unicode (Java UTF-16 String), decoded if necessary from a Python bytes object, using the file system encoding. In Jython, this encoding is UTF-8, irrespective of the OS platform. This method is comparable with Python 3 os.fsdecode, but for Java use, in places such as the os module. If the argument is not a PyUnicode, it will be decoded using the nominal Jython file system encoding. If the argument is a PyUnicode, its String is returned.

Parameters:

filename - as bytes to decode, or already as unicode

Returns:

unicode version of path

fileSystemDecode
```
public static java.lang.String fileSystemDecode(PyObject filename)
```
As fileSystemDecode(PyString) but raising ValueError if not a str or unicode.

Parameters:

filename - as bytes to decode, or already as unicode

Returns:

unicode version of the file name

fileSystemEncode
```
public static PyString fileSystemEncode(java.lang.String filename)
```
Return a PyString object we can use as a file name or file path in places where Python expects a bytes (that is a str) object in the file system encoding. In Jython, this encoding is UTF-8, irrespective of the OS platform.
This is subtly different from CPython's use of "file system encoding", which tracks the platform's choice so that OS services may be called that have a bytes interface. Jython's interaction with the OS occurs via Java using String arguments representing Unicode values, so we have no need to match the encoding actually chosen by the platform (e.g. 'mbcs' on Windows). Rather we need a nominal Jython file system encoding, for use where the standard library forces byte paths on us (in Python 2). There is no reason for this choice to vary with OS platform. Methods receiving paths as bytes will fileSystemDecode(PyString) them again for Java.

Parameters:

filename - as unicode to encode, or already as bytes

Returns:

encoded bytes version of path

fileSystemEncode
```
public static PyString fileSystemEncode(PyString filename)
```
Return a PyString object we can use as a file name or file path in places where Python expects a bytes (that is, str) object in the file system encoding. In Jython, this encoding is UTF-8, irrespective of the OS platform. This method is comparable with Python 3 os.fsencode. If the argument is a PyString, it is returned unchanged. If the argument is a PyUnicode, it is converted to a bytes using the nominal Jython file system encoding.

Parameters:

filename - as unicode to encode, or already as bytes

Returns:

encoded bytes version of path

getenv
```

getenv
```
public static PyString getenv(PyString name,
                              PyString defaultValue)
```
Get the value of the environment variable named from os.environ or return the given default value. Empty string values are treated as undefined for this purpose.

Parameters:

name - of the environment variable.

defaultValue - to return if key is not defined (may be null.

Returns:

the corresponding value or defaultValue.

getenv

public static java.lang.String getenv(java.lang.String name)

The same as getenv(name, null). See getenv(String, String).

getenv
```
public static java.lang.String getenv(java.lang.String name,
                                      java.lang.String defaultValue)
```
Get the value of the environment variable named from os.environ or return the given default value. This is a convenience wrapper on getenv(PyString, PyString) which takes care of the fact that environment variables are FS-encoded.

Parameters:

name - to access in the environment.

defaultValue - to return if key is not defined.

Returns:

the corresponding value or defaultValue.

Parameters:

console - The new Console object

Throws:

public static PyObject javaPyClass(PyObject cls,
                                   java.lang.Class<?> interfce)
```
Returns a Python-class that extends cls and interfce. If cls already extends interfce, simply cls is returned. Otherwise a new class is created (if not yet cached). It caches such classes and only creates a new one if no appropriate class was cached yet.

Returns:

a Python-class that extends cls and interfce

newJ
```
public static <T> T newJ(PyObject cls,
                         java.lang.Class<T> jcls,
                         java.lang.Object... args)
```
This method is a compact helper to access Python-constructors from Java. It creates an instance of cls and retruns it in form of jcls, which must be an interface. This method even works if cls does not extend jcls in Python-code. In that case, it uses javaPyClass(PyObject, Class) to create an appropriate class on the fly.
It automatically converts args to PyObjects.
For keyword-support use newJ(PyObject, Class, String[], Object...).

Parameters:

cls - - the class to be instanciated

jcls - - the Java-type to be returned

args - are automatically converted to Jython-PyObjects

Returns:

an instance of cls in form of the interface jcls

keywordss are applied to the last args in the list.

Parameters:

cls - - the class to be instanciated

Works like newJ(PyObject, Class, Object...), but looks up the Python-class in the module-dict using the interface-name, i.e. jcls.getSimpleName().
For keywords-support use newJ(PyModule, Class, String[], Object...).

module - the module containing the desired class

jcls - Java-type of the desired clas, must have the same name

args - constructor-arguments

Returns:

a new instance of the desired class
