# Activate Virtualenv
workon {{virtualenv_name}} import subprocess
# Activate Virtualenv
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"workon",
"<virtualenv_name>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: workon not found. Please install it first.")

run_command() When To Use
Before running scripts that depend on packages installed in a specific virtual environment.
Pro Tip
Use `deactivate` to exit the current environment; check for activated virtualenv in shell prompt.
