Opening Python script mode on a MacBook

I have a MacBook air and have tried opening Python in terminal but when I open it, it opens Python interactive mode. Does anyone know how to open Python script mode please.
I’ve tried typing in things such as Python or Python 3 like safari suggests but that didn’t work.

There is no 'script mode'. You can create a Python script using TextEdit or another editor, save it as myfile.py, and then run it with python myfile.py.

for running what you are calling 'script version' of python you should choose a python file to run and make sure is written in the same or in a compatible version to the python you are running it with (python2, python3)
For running an example script:
python main.py
You need to be in the directory containing the file so make sure you are there before running the command. Using python runs the first version of python you installed, so if you want to use an other you should use:
python2 main.py
python3 main.py
etc

Assuming you've stored your script in a file named itworks.py, the simplest thing is to type the command python3 itworks.py in a terminal window after you've moved to the directory containing the script. Alternatively, you can type python3 followed by a space, then locate your python script in the Finder and drag and drop it into the terminal. This will expand to the full path to the file, allowing you to run a script located elsewhere than your current directory. Don't forget to press return...
In older versions of MacOS you could say python, but that uses python 2 which is no longer supported so you should go with python3 for any new development. (With MacOS Ventura, python 2 seems to have been removed.)
If you have multiple versions of python, you can use the command which -a python3 (or python) to see all versions on your PATH, and the order in which they will be found. PATH works on a first-come-first-served basis, but you can override by using the fully qualified path name to an alternative python.
Yet another solution, for when you want a more permanent script you will use many times in the future, is to use a "shebang" line as the first line of your script. For example, I wrote the following tiny demo:
#!/usr/bin/env python3
print('It works!')
The first line says to parse this script with the first python3 interpreter found in your current environment's PATH. You could replace that with an explicit path such as #!/opt/homebrew/bin/python3. Now make the script executable: chmod a+x itworks.py. You can now run the script from the current directory by typing ./itworks.py. (The leading ./ tells your shell you know it's in the current directory, and is intended as protection against trojan horse scripts.) If you want to be able to use the now-executable script from anywhere, add it to a directory on your path such as /usr/local/bin, and you'll be able to run it by just typing itworks.py.

How to make Windows execute my Python script files when I click them

I have made a Python program that uses output.to_csv('results.csv'). When I run it in Spyder it creates that CSV file. But when I double click on it nothing happens. Cmd appears and closes but nothing on the folder, no results.csv.
What am I missing? What more do I have to do?

Run the program from the command line itself instead of double-clicking the .py file.
I assume you are on Windows since you mention CMD. First, cd into the directory containing your program. Then, run python <program>.py or python3 <program>.py depending on your installation.
This time, you will see any output or error messages that appear in CMD without it immediately closing.

If the .csv file really exists, you should be able to go to your File Explorer and find the file at the top of the "Quick Access" section. Right-click the file and hover over "Open With >". Then select Notepad and a notepad will open up showing your results.
If you do not see the file, then try running your program on the command prompt (for Windows):
Press the windows key and type "cmd" in the search bar.
Choose "Command Prompt"
Go to the dir of your program using the cd command
Type python <program name>.py
If there are no errors, follow the steps in the first paragraph.

Ok i guess windows is not recommended at all for this type of tasks. I mean running something simple as create such file is like trying to kill the Lernaean Hydra.
What i did is i just runned it with anaconda prompt and it worked sweet! Thanks for help. Thanks to all!
PS: I'm seriously considering changing to Linux after this
For anyone having the same problem, but have anaconda installed. 1) Open Anaconda Prompt, 2) use cd (1 space) then adress of the folder which contains your py program (eg. cd C:\Users\Bernie\Desktop\tasos) and hit enter, 3) on the next line that appears type: python program_name.py, 4)Hit enter, 5)success!

Python py not executing in other PC

I have a technical questions on python script.
I have developed code on my laptop and I want to move it in another one.
I installed python there, put when I try to double click on the .py file it is not working. Like the cmd screen goes away in a second.
Do you know why?
(if I open python through cmd it is working, so it is in path and it works)

What is probably happening is that there is an error being thrown on your new computer which causes command prompt to just instantly close.
The best way to run a python script is from an open command prompt/terminal. To do this open a command prompt and move into the directory of your python file. For example, if the file you are trying to run is located at C:\Users\Davide\PythonScripts, then open a command prompt and type
cd C:\Users\Davide\PythonScripts
Now your command window is in the folder that you want to run files out of.
Next you want to tell Python to run your script. This can be done by typing "python ". For example, if your script is name my_script.py, you would type
python my_script.py
What this is doing is telling your computer "open an instance of Python where you are running my_script.py." If there are any errors thrown, the command window will stay open after python closes and you can see what is going on.
Most likely, there is a package you are trying to import which it cannot find because it was not installed on your other computer. If at the top of your file you have "import xxx" or "from xxx import yyy" lines, your other computer might not be finding those modules and just throwing an error that instantly closes command prompt when you just double click the .py file.

Running Python Programs from a Terminal

I am working on page 16, chapter 1, in the book "Python Crash Course" by Eric Matthes. I am trying to run my hello_world.py python program from my Windows terminal.
The directions say to:
Open a new terminal window and issue the following commands to run hello_world.py:
C:\> **cd Desktop\python_work**
C:\Desktop\python_work> **dir**
hello_world.py
C:\Desktop\python_work> **python hello_world.py**
Hello Python world!
python_work is my python work folder on my desktop. In my Windows terminal, I have tried entering the code with and without the unbolded C:\>. It has given me an error message: The system cannot find the path specified. I'm probably doing something wrong, but I don't know what's wrong.

Assuming your getting your error when you execute "python hello_world.py", Python might not be installed correctly. More likely is that you are not in the correct directory. Do the following commands:
cd "C:\Desktop\python_work"
python hello_world.py
If that does not work, I can only assume one of two things:
Either the folder or the .py file is not named what you think it is and you should rename whichever one, or python is not installed correctly and you should reinstall it.

use
cd C:\Desktop\python_work
to change your working directory and then type
hello_world.py
to launch your program or if that doesn't work try
python hello_world.py
alternatively (what I do), assuming the first option worked, you can create a .bat file with the following code.
#echo off
"%~dp0\hello_world.py" %*
pause
and then just put that bat file in the same folder as "hello_world.py" and when you run the bat file it will launch the script. :)

Run python source file from PowerShell

I'm trying to learn python but have some problem running source files from power shell. When I type 'python' it opens up and I can type python commands directly in the shell. I think this is called interactive mode. But when I try to run/execute a source file I get an error message: It sayys: Syntax error: invalid syntax.
I use 'python myfile.py' when I try to execute the script.
If I run the same file from IDLE it works just fine. Ana idea what I'm doing wrong?
Here is myfile.py. I'm running python 2.7
# filename: myfile.py
while True:
s = raw_input('Enter something: ')
if s == 'Quit':
break
print 'Lenght of the string is', len(s)
print 'Done'

You might have more than one version of Python installed and the version IDLE is using is newer. To see what version of python you have you can type >python -V at a command line. If that version looks appropriate then you might need the full path to the file as the second parameter. E.g >python C:\myfile.py.
If you installed Python correctly there is always a chance that just typing the name of the script will run it with python. E.g. >myfile.py
I always find that adding C:\Python27 to the %PATH% variable and .PY to the %PATHEXT% variable makes running scripts easier. In this case just >myfile should work.
Edit after Update:
Typing just >python with no parameters opens python in 'interactive mode' which is different from the batch or scripting mode that your script is intended for. If executed with arguments the first argument is taken as the file path and further arguments are passed to the script in the sys.argv list.

You will need to put the full path of the Python executable within the command line in order for it to work. You could check and ensure that your python exe is included in your Path among your system variables.

Disclaimer: I don't know PowerShell, but I do know cmd.exe.
I don't know why python myfile.py doesn't work, but assuming that PowerShell bears at least some similarity to cmd.exe, the following should probably work: myfile.py. That's right, just enter the name of the Python script and hit enter.

If you started by typing "python" in powershell you will need to get out of that script.
If you are in python type:
quit()
then type
python myfile.py
This should work if your python is installed correctly.

Try to type this in Powershell:
$env:path="$env:Path;C:\Python33
After this, command
python yourfile.py
should work.

This my sound silly, especially coming from a beginner.
Just save the file on your desktop. Open up powershell and drag the file directly into powershell and it opens. kind of tedious but it works
