Creating a BAT file for python script

Question

How can I create a simple BAT file that will run my python script located at C:\somescript.py?

Answer 1

c:\python27\python.exe c:\somescript.py %*

Answer 2

Open a command line (⊞ Win+R, cmd, ↵ Enter) and type python -V, ↵ Enter.

You should get a response back, something like Python 2.7.1.

If you do not, you may not have Python installed. Fix this first.

Once you have Python, your batch file should look like

@echo off
python c:\somescript.py %*
pause

This will keep the command window open after the script finishes, so you can see any errors or messages. Once you are happy with it you can remove the 'pause' line and the command window will close automatically when finished.

Answer 3

Here's how you can put both batch code and the python one in single file:

0<0# : ^
''' 
@echo off
echo batch code
python "%~f0" %*
exit /b 0
'''

print("python code")

the ''' respectively starts and ends python multi line comments.

0<0# : ^ is more interesting - due to redirection priority in batch it will be interpreted like :0<0# ^ by the batch script which is a label which execution will be not displayed on the screen. The caret at the end will escape the new line and second line will be attached to the first line.For python it will be 0<0 statement and a start of inline comment.

Answer 4

Just simply open a batch file that contains this two lines in the same folder of your python script:

somescript.py
pause

Answer 5

If you've added Python to your PATH then you can also simply run it like this.

python somescript.py

Answer 6

You can use python code directly in batch file, https://gist.github.com/jadient/9849314.

@echo off & python -x "%~f0" %* & goto :eof
import sys
print("Hello World!")

See explanation, Python command line -x option.

Answer 7

--- xxx.bat ---

@echo off
set NAME1="Marc"
set NAME2="Travis"
py -u "CheckFile.py" %NAME1% %NAME2%
echo %ERRORLEVEL%
pause

--- yyy.py ---

import sys
import os
def names(f1,f2):

    print (f1)
    print (f2)
    res= True
    if f1 == "Travis":
         res= False
    return res

if __name__ == "__main__":
     a = sys.argv[1]
     b = sys.argv[2]
     c = names(a, b) 
     if c:
        sys.exit(1)
    else:
        sys.exit(0)        

Answer 8

Similar to npocmaka's solution, if you are having more than one line of batch code in your batch file besides the python code, check this out: http://lallouslab.net/2017/06/12/batchography-embedding-python-scripts-in-your-batch-file-script/

@echo off
rem = """
echo some batch commands
echo another batch command
python -x "%~f0" %*
echo some more batch commands
goto :eof

"""
# Anything here is interpreted by Python
import platform
import sys
print("Hello world from Python %s!\n" % platform.python_version())
print("The passed arguments are: %s" % sys.argv[1:])

What this code does is it runs itself as a python file by putting all the batch code into a multiline string. The beginning of this string is in a variable called rem, to make the batch code read it as a comment. The first line containing @echo off is ignored in the python code because of the -x parameter.

it is important to mention that if you want to use \ in your batch code, for example in a file path, you'll have to use r"""...""" to surround it to use it as a raw string without escape sequences.

@echo off
rem = r"""
...
"""

Answer 9

This is the syntax: "python.exe path""python script path"pause

"C:\Users\hp\AppData\Local\Programs\Python\Python37\python.exe" "D:\TS_V1\TS_V2.py"
pause

Basically what will be happening the screen will appear for seconds and then go off take care of these 2 things:

1. While saving the file you give extension as bat file but save it as a txt file and not all files and Encoding ANSI
2. If the program still doesn't run save the batch file and the python script in same folder and specify the path of this folder in Environment Variables.

Answer 10

If this is a BAT file in a different directory than the current directory, you may see an error like "python: can't open file 'somescript.py': [Errno 2] No such file or directory". This can be fixed by specifying an absolute path to the BAT file using %~dp0 (the drive letter and path of that batch file).

@echo off
python %~dp0\somescript.py %*

(This way you can ignore the c:\ or whatever, because perhaps you may want to move this script)

Answer 11

Use any text editor and save the following code as runit.bat

@echo off
title Execute Python [NarendraDwivedi.Org]
:main
echo.
set/p filename=File Name :
echo. 
%filename%
goto main

Now place this file in the folder where python script is present. Run this file and enter python script's file name to run python program using batch file (cmd)

Answer 12

Create an empty file and name it "run.bat"

In my case i use "py" because it's more convenient, try:

C:
cd C:\Users\user\Downloads\python_script_path
py your_script.py

Answer 13

@echo off
call C:\Users\[user]\Anaconda3\condabin\conda activate base
"C:\Users\[user]\Anaconda3\python.exe" "C:\folder\[script].py"

Answer 14

ECHO OFF
set SCRIPT_DRIVE = %1
set SCRIPT_DIRECTORY = %2
%SCRIPT_DRIVE%
cd %SCRIPT_DRIVE%%SCRIPT_DIRECTORY%
python yourscript.py`

Answer 15

i did this and works: i have my project in D: and my batch file is in the desktop, if u have it in the same drive just ignore the first line and change de D directory in the second line

in the second line change the folder of the file, put your folder

in the third line change the name of the file

D: cd D:\python_proyects\example_folder\ python example_file.py

Answer 16

start xxx.py

You can use this for some other file types.
