If you receive the error -bash: python: command not found when trying to run the python command in a BASH shell, it means that the python executable is not in your shell's search path. This can happen if the python executable is not installed on your system, or if it is not added to your shell's search path.
To solve this error, you have a few options:
Install the python executable on your system, if it is not already installed. Depending on your operating system, this may involve downloading and installing a package from the Python website, or using a package manager like apt or yum to install the python package.
Add the directory containing the python executable to your shell's search path. This can be done by adding the following line to your shell's configuration file (e.g. .bashrc, .bash_profile, etc.):
export PATH=$PATH:/path/to/python
Replace /path/to/python with the actual path to the python executable on your system.
python executable when running the command. For example, if the python executable is located in the /usr/local/bin directory, you can run it using the following command:/usr/local/bin/python
This should allow the shell to find and execute the python executable, even if it is not in the search path.
Note that the specific steps for solving this error may vary depending on your operating system and the exact configuration of your system. If you are still having trouble, you may need to consult the documentation for your operating system or seek help from more experienced users.
