+* Outline
+  - Opening and reading contents of a file
+  - Closing open files
+  - Reading all the contents of the file at once
+  - Reading files line by line
+* Question 1
+  Split the variable into a list, =pend_list=, of the lines in the
+  file. Hint, use the tab command to see what methods the string
+  variable has.
+* Solution 1
+  #+begin_src python
+    In []: pend_list = pend.splitlines()
+    
+    In []: pend_list
+  #+end_src
+* Question 2
+  Re-open the file =pendulum.txt= with =f= as the file object.
+* Solution 2
+  #+begin_src python
+    In []:   f = open('/home/fossee/pendulum.txt')
+  #+end_src
+* Summary
+  - Opening a file using =open= function
+  - Reading all the contents of the file at once using =read()= method
+  - Closing open files using the =close= method
+  - Reading files line by line by iterating using a =for= loop
+* Thank you!
