Question

I am getting an error when running a python program   Traceback  most recent call last     File  C  Program Files  x86  Wing IDE 101 4 1 src debug tserver  sandbox py   line 110  in  lt module gt    File  C  Program Files  x86  Wing IDE 101 4 1 src debug tserver  sandbox py   line 27  in   init     File  C  Program Files  x86  Wing IDE 101 4 1 src debug tserver class inventory py   line 17  in   init   builtins NameError  global name  xrange  is not defined   The game is from here   What causes this error

Replace   Python 2 xrange to   Python 3 range  Rest all same

User · Answer

add xrange range in your code    It works to me

User · Answer

in python 2 x  xrange is used to return a generator while range is used to return a list  In python 3 x   xrange has been removed and range returns a generator just like xrange in python 2 x  Therefore  in python 3 x you need to use range rather than xrange

You are trying to run a Python 2 codebase with Python 3  xrange   was renamed to range   in Python 3   Run the game with Python 2 instead  Don t try to port it unless you know what you are doing  most likely there will be more problems beyond xrange   vs  range     For the record  what you are seeing is not a syntax error but a runtime exception instead     If you do know what your are doing and are actively making a Python 2 codebase compatible with Python 3  you can bridge the code by adding the global name to your module as an alias for range   Take into account that you may have to update any existing range   use in the Python 2 codebase with list range       to ensure you still get a list object in Python 3    try        Python 2     xrange except NameError        Python 3  xrange is now named range     xrange   range    Python 2 code that uses xrange      unchanged  and any   range      replaced with list range         or replace all uses of xrange      with range      in the codebase and then use a different shim to make the Python 3 syntax compatible with Python 2   try        Python 2 forward compatibility     range   xrange except NameError      pass    Python 2 code transformed from range      - gt  list range       and   xrange      - gt  range         The latter is preferable for codebases that want to aim to be Python 3 compatible only in the long run  it is easier to then just use Python 3 syntax whenever possible

I solved the issue by adding this import More info  from past builtins import xrange

User · Answer

I agree with the last answer But there is another way to solve this problem You can download the package named future such as pip install future And in your  py file input this  from past builtins import xrange  This method is for the situation that there are many xranges in your file
