 The code runs directly with variable substitution. Assign any "Available Variables" used to a new standard variable first, then use that variable in the code. Use triple quotes and curly braces since the substituted content may contain quotes/newlines.
 
 Example:
-my_var = \"\"\"{{response}}\"\"\"
-filename = \"\"\"{{outputfile}}\"\"\"
-with open(filename, 'w') as f:
-    f.write(my_var)
+my_var = \"\"\"{{variable}}\"\"\"
