+# Modules in Python are just Python files with a .py extension. The name of the module is the same as the file name. A Python module can have a set of functions, classes, or variables defined and implemented. The example above includes two files:
+# mygame/
+# mygame/game.py
+# mygame/draw.py
+# The Python script game.py implements the game. It uses the function draw_game from the file draw.py, or in other words, the draw module that implements the logic for drawing the game on the screen.
+# Modules are imported from other modules using the import command. In this example, the game.py script may look something like this:
+
+# game.py
+# import the draw module
+import draw
+
+def play_game():
+    pass
+
+def main():
+    result = play_game()
+    draw.draw_game(result)
+
+# this means that if this script is executed, then 
+# main() will be executed
+if __name__ == '__main__':
+    main()
+
+
+# A namespace is a system where every object is named and can be accessed in Python. We import the function draw_game into the main script's namespace by using the from command.
+# game.py
+# import the draw module
+from draw import draw_game          #To import all objects instead of "draw_game" write '*'
+
+def main():
+    result = play_game()
+    draw_game(result)
+
+
+# Exercise
+# In this exercise, print an alphabetically sorted list of all the functions in the re module containing the word find.
+import re
+
+# Your code goes here
+import re
+
+# Your code goes here
+find_members = []
+for member in dir(re):
+    if "find" in member:
+        find_members.append(member)
+
+print(sorted(find_members))
