Python（在 Win10 上）：将“\”替换为“/”的路径问题

Question

Preface: I am a beginner to Python

Problem statement: I am writing a script wherein I will be launching an application ( Gotit.exe ) sitting at particular path lets say D:\Some Folder\SomeMore Folder\AgainFolder\myPythonFolder\Gotit.exe . I have kept the python-script also in myPythonFolder .

I am accessing the folder path via os.path.dirname(os.path.realpath(__file__)) and selecting particular application by appending it with \Gotit.exe but when passing the same appended string stored in a variable ie GotitexePath to os.system(GotitexePath) its throwing error as,

'D:\Some ' is not recognized as an internal or external command, operable program or batch file.**

Kindly help me out to solve the said issue

I am using python 3.8.2 on Win10 Machine

Answer 1

The error is pointing to Some Folder name. Since there is a space in path you provide, the system doesn't know whether it is a part of folder name or it is a next argument to the command.

You need to escape the blank space. There are multiple ways to to it. For example wrap the path with double quotes:

"D:\Some Folder\SomeMore Folder\AgainFolder\myPythonFolder\Gotit.exe"

For more ways see this post

Answer 2

os.system("\"%s\"" % GotitexePath)

A the previous replies say, you need to add additional quotation marks around the path for the windows command line.
