Importing Bash Variables
To import a Bash variables to a python script, you can make use of environment variables by following the steps below:
In your Bash script, export the variable as an environment variable using the
export
command. For example, let's say you want to export a variable calledMY_VARIABLE
:export MY_VARIABLE="Hello, World!"
In your Python script, you can access the environment variable using the
os
module. Import theos
module at the beginning of your Python script:import os
Access the environment variable using the
os.environ
dictionary, which provides access to all the environment variables. Retrieve the value of the variable using its name:my_variable = os.environ.get('MY_VARIABLE')
The
os.environ.get()
function retrieves the value of the environment variable specified by the argument (MY_VARIABLE
in this case). It returnsNone
if the variable is not found.Now, you can use the
my_variable
variable in your Python script:print(my_variable) # Output: Hello, World!
To run the scripts, you can also execute the following commands in the terminal:
$ source script.sh # Set the Bash variable
$ python script.py # Run the Python scriptThe output will be:
Hello, World!
By sourcing the Bash script, the environment variable is made available to the Python script. The Python script then accesses the value of the environment variable using
os.environ.get()
.
