214+
finally just give me a python code without any note that can generate a project folder with the
215+
given schema without ```python entry. and we dont need any base directory in the python code.
216+
the final ansible template must work very well without any error!
217+
218+
the python code you give me, must have structure like that:
219+
220+
import os
221+
project_name = "app/media/MyAnsible"
222+
foo_dir = os.path.join(project_name, "bar")
223+
x_dir = os.path.join(modules_dir, "y")
224+
225+
# Create project directories
226+
os.makedirs(ansible_dir, exist_ok=True)
227+
228+
# Create main.tf
229+
with open(os.path.join(project_name, "main.tf"), "w") as main_file:
230+
# any thing you need
231+
"""
