Python 脚本不会从命令行运行。 它显示没有错误

Question

I'm trying to run a simple Python Script on the CMD but nothing happens when I run it. I get no errors or anything. The py script is just a simple print ("Hello World").

All my.py files are in the Python/Projects file.

Just some context regarding this: I did install Python then Pycharm then Anaconda. I don't know if that has anything to do with conflicting Python files.

Answer 1

python isn't in your path. Checkout Adding directory to PATH Environment Variable in Windows , which is a good reference to the question of adding a variable to the path in CMD.

Answer 2

Are you sure you entered your command line query correctly?

python python_file_name.py

If you just entered your file_name.py it might have executed it but ended it simultaneously before you could see any result.

also try putting your file_name in double quotes.

Answer 3

If you have Python in PATH but script execution still doesn't work, inspect the C:\Users<user>\AppData\Local\Microsoft\WindowsApps folder.

There might be a zero-size python.exe file. It seems that this folder is earlier in PATH and zero-byte file intercept the console command execution. The microsoft store is opened with python page if I run that file. I removed this folder and python script start working again.

You also can ensure the correct python is available to the terminal with 'where python' to see the full path.

Answer 4

From your screenshot, you'd need to call

python "Hello World.py"

with quotes , not

python Hello World.py  // no, won't work

The reason is, when you don't include quotes around a filename with a space, it only takes the FIRST thing you wrote as the script name, the rest of the "words" are just passed as "command line arguments"
