| 1475265 | 2021-02-27 06:43:00 | I have a data file, called myInput, in a directory called c:MyProject I have a python program, called myProcess, also in c:MyProject I want to run the batch file, also stored in c:Myproject The environment variable is set to point to c:\python32 which is where my python lives DOS BATCHFILE python process.py -i myInput.txt dir /w pause ERROR MESSAGE: When I run my batch file I get the error message "c: python was not found" The environment variable should have told it where to look for python surely? NOTE: If I copy MY DATA, PROGRAM and my BATCH file into c:\python32 directory it works! But I don't want to do that. Thanks in advance SYSTEM: W10 |

| 1475266 | 2021-02-27 06:55:00 | I found that this works... BATCHFILE c:\python32\python.exe process.py -i myInput.txt dir /w pause BUT it still doesn't explain why my environment variable doesn't work! |

| 1475267 | 2021-02-27 08:52:00 | What environment variable is set to c:\python? If it’s pythonhome that doesn’t help with Executing python from anywhere. You need to add c:\python to the PATH environment variable |

| 1475268 | 2021-02-27 21:05:00 | Also make sure that the Python path is set under System Variables and NOT User Variables. | chiefnz (545) | ||
| 1475269 | 2021-02-28 19:55:00 | path C:\python32 :) smiley face is optional in DOS Better way(?) would be to add this to the start bat file CD\ CD c:\python32 |

Environment variables exist because "standard paths" for programming languages/compilers etc became "normal" over time. |
