Automated Python 2 to 3 code translation! This web is a online converter that reads Python 2.x source code and applies a series of fixers to transform it into valid Python 3.x code Enter your Python2 code on the left, hit the button, and boom, Python3 code on the right. Python Reference Java Reference. Convert From Python to JSON. If you have a Python object, you can convert it into a JSON string by using the json.dumps method. Convert from Python to JSON: import json # a Python object (dict): x = 'name': 'John'. Conversion Issue. Dim A as Integer B = 20 Sub DotIt (X as Double) Select Case A Case 1 B = B + X Case 2 B = B - X Case Else B = 0 End Select End Sub Function GetHalfB As Integer GetHalfB = B / 2 End Function. ' ' Multi-line and singe-line ifs are converted to blocks in Python If A = 10 Then DoSomething ElseIf B = 20 Then.

  • Optional 'thank-you' note:
Need help converting java code into python. I am new to python and I am confused on how I should go about this conversion. Thank you for your help. (I want to XOR a decoded string with an ascii character)

Here is what I have so far

The definition of a compiler is translates from a higher level language to a lower level language. Eg python to machine-code. Or java to javascript (google has a rather famous compiler for this somewhere - its' what makes google doc easier to make) Python to javascript compilers abound. Technically javascript to python would be a decompiler.

Updated code but still not working with how i expect it to.

  • Optional 'thank-you' note:
Start by giving variables proper names. Arrays don't have charAt() methods, so array is a poor name for a String.
Don't try to convert code like that. Write down what the code is supposed to do. Then you are probably better off programming it anew.
Say what goes wrong.
Make sure you use correct formatting. Why have you not used {} in the Java®? Why are you double‑spacing your code? Why is there a print instruction inside a loop in the Python and no print() statement at all in the Java®?

A more pythonic way to do this in Python 2.7 is:

By contrast, here is the same function in python 3.7:

Notes:
  • Range/Xrange: The ending number needs to be 128 in python since range does not include the final number.

  • For statement: In python the for statement can make available the character directly rather than only an index. Also, the enumerate function wraps the value and returns a tuple containing both a counter and the value itself -- which the for statement is happy to accept.

  • Final print statement: The substring reference '[:-1]' chops off the final vertical bar without the bother of creating yet another string.

  • Variable names: The variable names have been changed to be more descriptive. Also, python prefers using lower case and underscores for variable names rather than Java's camel case naming convention. (One is not better than the other-- just different.)

  • The Python 3 code is slightly longer because it defaults to Unicode strings. Byte arrays -- when printed -- produce different output.

  • Python 3.6 and later have the 'fstrings' which make the print statements more compact.

    • Hopefully this will help with efforts to convert code from java to python.

    java2python claims to be a simple but effective tool to translate Java source code into Python source code. Troy Melhase, the creator of the java2python project has announced the first release.

    java2python is licensed under the GNU General Public License 2.0. To translate code, java2python requires python 2.5, ANTLR and PyANTLR.
    The following is working with java2python 0.1 version:

    * class definitions, inner class definitions
    * method definitions
    * most expressions
    * if statements, for statements, while statements
    * raises statement
    * type translation (e.g, String -> str)
    * class member access to instance attributes

    Troy Melhasesays “I’ve written java2python with the idea that it should provide ahigh degree of customization to the generation process. It allows formultiple, cumulative configuration modules, which means you can have aconfiguration for an entire translation project, and also haveconfigurations for individual modules.

    Let me add a few more waffles before concluding. Yes, I know Python isnot Java. Yes, I know that this tool doesn’t translate the meaning ofthe input source code. Yes, the tool does not produce idiomatic Python.And yes, I know the tool isn’t even close to perfect. But even with allof those problems, I know this is better than what I was doing.”

    java2python is available on Google code at http://code.google.com/p/java2python/
