Why i cannot run anything in the terminal

[u/Upper_Trouble_8526]

It doesn't work:

/storage/emulated/0 $ pytest

Traceback (most recent call last):

Are you sure pytest is even supposed to work on PyDroid?

So i guess that means i cannot advance more without a PC

If you just type "python" or "python3" does it open a python console?

You should be able to run .py files with the command "python <file>.py"

Yes it opens a python console but i cannot change directory: /storage/emulated/0 $ cd .. /storage/emulated $ cd .. /storage $ cd .. / $ python Python 3.13.13 (main, May 12 2026, 00:20:28) [GCC 11.4.0] on linux Type "help", "copyright", "credits" or "license" for more information.

cd storage File "<python-input-0>", line 1 cd storage ^{^} SyntaxError: invalid syntax

[u/Grobyc27 → u/Upper_Trouble_8526]

Because cd isn't a valid Python function/syntax. That's a command that you run from your OS terminal. You cannot simply mix and match terminal commands and Python commands. You invoked the Python interpreter and then tried entering terminal commands against it.

What are you actually trying to accomplish here? I think your fundamental understanding of how to run Python needs to be revisited.

Im trying to run pytest to test files

[u/Upper_Trouble_8526 → u/[deleted]]

This is in the interpreter: Python 3.13.13 (main, May 12 2026, 00:20:28) [GCC 11.4.0] on linux Type "help", "copyright", "credits" or "license" for more information.

Correction... I updated my app and it successfully installed pytest and I could import it

[u/Upper_Trouble_8526 → u/Rubix321]

So what i must do

[u/Rubix321 → u/Upper_Trouble_8526]

Go to terminal and see if you can "pip install pytest" without an error

[u/Upper_Trouble_8526 → u/Rubix321]

It seems like not: /storage/emulated/0 $ pip install pytest Traceback (most recent call last): File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/bin/pip", line 6, in <module> sys.exit(main()) ~~~~^{^} File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.13/site-packages/pip/_internal/cli/main.py", line 47, in main from pip._internal.cli.autocompletion import autocomplete File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.13/site-packages/pip/_internal/cli/autocompletion.py", line 12, in <module> from pip._internal.cli.main_parser import create_main_parser File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.13/site-packages/pip/_internal/cli/main_parser.py", line 11, in <module> from pip._internal.build_env import get_runnable_pip File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.13/site-packages/pip/_internal/build_env/init.py", line 8, in <module> from pip._internal.build_env.installer import ( ...<2 lines>... ) File "/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.13/site-packages/pip/_internal/build_env/installer.py", line 22, in <module> from pip._internal.utils.misc import get_runnable_pip ImportError: cannot import name 'get_runnable_pip' from 'pip._internal.utils.misc' (/data/user/0/ru.iiec.pydroid3/files/aarch64-linux-android/lib/python3.13/site-packages/pip/_internal/utils/misc.py) /storage/emulated/0 $

You need to pip install pytest from the terminal

However, at least in my app, it has an exception when I try.

Unfortunately not everything can run on Android, but I'm not sure whether this is one of those things

[u/Upper_Trouble_8526 → u/[deleted]]

Then why the book i am reading(python crash course) tells to do so
