How can I Save a Python Script output to a file when using Command Prompt?

Question

I am using a speech-to-text example from Microsoft example here.

After following the steps, we can run the example with this command (in command prompt)

python3 main.py

And, in the command prompt all the results are showed. Great!

However, I want to save all the results into a file (could be JSON, txt, csv...). I saw on Stackoverflow some other persons with the same issue here (however this is not really working in my example), and I knew from a previous project that I could save results to a JSON file (with Scrapy), with a command like this:

scrapy crawl Script -o name_json_file.json

Therefore my question: Can I - directly save - all the results (that the Command Prompt shows) to a file when using the command prompt? And if not, what is the best (alternative) way to save the outputs in a file?

Many thanks!

What you are looking for is

YOUR-COMMAND > c:\PATH\TO\FOLDER\OUTPUT.txt

so in your case its

python3 main.py > c:\PATH\TO\FOLDER\OUTPUT.txt

If you want to save and also view the output you can do

python3 main.py > c:\PATH\TO\FOLDER\OUTPUT.txt | type

For completeness: in some situation output might also be written to stderr, then you need to use &> instead of just >.

Looks good! Especially the last one is interesting for my example. However, I receive a "The syntax is incorrect" when trying python main.py >output_text.txt | type are you sure that the syntax is ok? Thanks in advance!

Yeah the syntax is fine ensure you are using the right version of python. In the comment you wrote python main.py but in the question and the instructions it says python3 main.py.

@Roverflow the space between > and output_text.txt is important
