从批处理文件中调用 python 行

Question

I see here that I can call a python script from a batch file.

What I want to do is calling a python line without using a script.

This is an example of what i'm trying to do:

>> echo 'python.exe ''' "this/is/a/path".replace('/','\\')'''  '

would return "this\\is\\a\\path"

Note: there is an easier way of doing what i'm trying to do in my example like here but this is not the question:)

Answer 1

You can use the -c flag:

Specify the command to execute (see next section). This terminates the option list (following options are passed as arguments to the command).

python -c '''print("this/is/a/path".replace("/","\\"))'''
> this\is\a\path

Answer 2

this will work, thanks to @E.Serra approach.

echo print("this/is/a/path".replace("/","\\"))  > tmp_file && python tmp_file && rm tmp_file

-->

C:\Python27>echo print("this/is/a/path".replace("/","\\"))  >tmp_python_File && python tmp_python_File && rm tmp_python_File
this\is\a\path

Answer 3

OK, if you are just trying to run your python.exe then:

python python.exe 

If you want to run perl style oneliners then:

echo '''print("this/is/a/path".replace("/","\\"))'''  >tmp_python_File && python tmp_python_File && rm tmp_python_File

Spits:

$> this\is\a\path
