error on bat file

[Sanlus]

py.exe get installed in Windows folder when install Python37. Can be used to accessing previous version or current,can also install with pip to all version installed. Example:

# Python version set in Windows Path C:\>python -V Python 3.7.0 # Can also access with py C:\>py -3.7 -V Python 3.7.0 # Older version i have C:\>py -2.7 -V Python 2.7.9 C:\>py -3.4 -V Python 3.4.2 C:\>py -3.5 -V Python 3.5.2 C:\>py -3.6 -V Python 3.6.4 

Use py to install with pip to eg 2.7.

λ py -2.7 -m pip install logzero Requirement already satisfied: logzero in c:\python27\lib\site-packages

Making bat hello.bat. Use python main version,pause in bat so cmd window doesn't close immediately. Can also put this last in code input('Press Enter to exit').

@echo off python C:/foo/hello.py %* pause 

If want to run 2.7 in a bat file,then use py.

@echo off py -2.7 C:/foo/hello.py %* pause

now i have syntax error on off in @echo off. rip
