    32 * Outline
       
    33   - Opening and reading contents of a file
       
    34   - Closing open files
       
    35   - Reading all the contents of the file at once
       
    36   - Reading files line by line
       
    37 * Question 1
       
    38   Split the variable into a list, =pend_list=, of the lines in the
       
    39   file. Hint, use the tab command to see what methods the string
       
    40   variable has.
       
    41 * Solution 1
       
    42   #+begin_src python
       
    43     In []: pend_list = pend.splitlines()
       
    44     
       
    45     In []: pend_list
       
    46   #+end_src
       
    47 * Question 2
       
    48   Re-open the file =pendulum.txt= with =f= as the file object.
       
    49 * Solution 2
       
    50   #+begin_src python
       
    51     In []:   f = open('/home/fossee/pendulum.txt')
       
    52   #+end_src
       
    53 * Summary
       
    54   - Opening a file using =open= function
       
    55   - Reading all the contents of the file at once using =read()= method
       
    56   - Closing open files using the =close= method
       
    57   - Reading files line by line by iterating using a =for= loop
       
    58 * Thank you!
