How to get the python3 path in ubuntu without which command - linux

Question

Problem:
I want to get the python3 path in my Ubuntu VM. Like /usr/xyz/python3
More Information:
I dont see the 'which' command present in my envt.
I tried to 'sudo apt install which', but it fails saying that no such package found.

Answer 1

Get path of the executable python binary
Python code
import sys
print(sys.executable)
Command
python -c "import sys; print(sys.executable)"

Answer 2

sudo apt install which is failing because which is part of debianutils; most executables don't come as their own package.
sudo apt install debianutils

Answer 3

If you use bash, you can just do :
type -p python

Answer 4

The where and which commands are often an alias to the inbuilt bash command type.
I have it also as app in busybox on most embedded devices.
Also tablets and smartfons with the app: ConnectBot
If present on your machine too; then: type -p python3
But anyway, the correct/recommended way to make a SHEBANG is not to use type, where or which.
If your PATH environment variable targets the usually folders for installed executables just use: #!/usr/bin/env python3
Example: test.py
#!/usr/bin/env python3
import sys
print('No error - But i return 1 and not 0')
sys.exit(1)
Making than executable with: chmod +x test.py
And execute it...
$ ./test.py
No error - But i return 1 and not 0
