    <p>I'm having trouble importing my code into the python interpreter (powershell). I open python through powershell and when I type in "import ex24" simply nothing appears, this is using the code I copy and pasted from his site (Just to be sure):</p> <pre><code>def break_words(stuff): """This function will break up words for us.""" words = stuff.split(' ') return words def sort_words(words): """Sorts the words.""" return sorted(words) def print_first_word(words): """Prints the first word after popping it off.""" word = words.pop(0) print word def print_last_word(words): """Prints the last word after popping it off.""" word = words.pop(-1) print word def sort_sentence(sentence): """Takes in a full sentence and returns the sorted words.""" words = break_words(sentence) return sort_words(words) def print_first_and_last(sentence): """Prints the first and last words of the sentence.""" words = break_words(sentence) print_first_word(words) print_last_word(words) def print_first_and_last_sorted(sentence): """Sorts the words then prints the first and last one.""" words = sort_sentence(sentence) print_first_word(words) print_last_word(words) </code></pre> <p>When he executes it he gets this:</p> <pre><code>&gt;&gt;&gt; import ex25 &gt;&gt;&gt; sentence = "All good things come to those who wait." &gt;&gt;&gt; words = ex25.break_words(sentence) &gt;&gt;&gt; words ['All', 'good', 'things', 'come', 'to', 'those', 'who', 'wait.'] &gt;&gt;&gt; sorted_words = ex25.sort_words(words) &gt;&gt;&gt; sorted_words ['All', 'come', 'good', 'things', 'those', 'to', 'wait.', 'who'] &gt;&gt;&gt; ex25.print_first_word(words) All &gt;&gt;&gt; ex25.print_last_word(words) wait. &gt;&gt;&gt; wrods Traceback (most recent call last): File "&lt;stdin&gt;", line 1, in &lt;module&gt; NameError: name 'wrods' is not defined &gt;&gt;&gt; words ['good', 'things', 'come', 'to', 'those', 'who'] &gt;&gt;&gt; ex25.print_first_word(sorted_words) All &gt;&gt;&gt; ex25.print_last_word(sorted_words) who &gt;&gt;&gt; sorted_words ['come', 'good', 'things', 'those', 'to', 'wait.'] &gt;&gt;&gt; sorted_words = ex25.sort_sentence(sentence) &gt;&gt;&gt; sorted_words ['All', 'come', 'good', 'things', 'those', 'to', 'wait.', 'who'] &gt;&gt;&gt; ex25.print_first_and_last(sentence) All wait. &gt;&gt;&gt; ex25.print_first_and_last_sorted(sentence) All who </code></pre> <p>Also, when I manually type out the code like I usually do, I get this error. I can't to seem what mistake I made:</p> <blockquote> <blockquote> <blockquote> <p>import ex25 Traceback (most recent call last): File "", line 1, in File "ex25.py", line 1 SyntaxError: Non-ASCII character '\xff' in file ex25.py on line 1, but no encoding declared; eps/pep-0263.html for details</p> </blockquote> </blockquote> </blockquote> <p>This is my manual copy (ex25):</p> <pre><code>def break_words(stuff): """This function will break up words for us.""" words = stuff.split(' ') return words def sort_words(words): """Sorts the words""" return sorted (words) def print_first_word(words): """Prints the first word after popping it off""" word = words.pop(0) print word def print_last_word(words): """Prints the last word after popping it off""" word = words.pop(-1) print word def sort_sentence(sentence): """Takes in a full sentence and returns the sorted words.""" words = break_words(sentence) return sort_words(words) def print_first_and_last(sentence): """Prints the first and last words of the sentence.""" words = break_words(sentence) print_first_word(words) print_last_word(words) def print_first_and_last_sorted(sentence): """Sorts the words then prints the first and last one.""" words = sort_sentence(sentence) print_first_word(words) print_last_word(words) </code></pre>

    2. COIf you import it and nothing happens, there's nothing wrong with that. Your script doesn't actually run anything, so it shouldn't do anything.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
