    <p>allow me to preface this by saying that i am learning python on my own as part of my own curiosity, and i was recommended a free online computer science course that is publicly available, so i apologize if i am using terms incorrectly. </p> <p>i have seen questions regarding this particular problem on here before - but i have a separate question from them and did not want to hijack those threads. the question:</p> <p>"a substring is any consecutive sequence of characters inside another string. The same substring may occur several times inside the same string: for example "assesses" has the substring "sses" 2 times, and "trans-Panamanian banana" has the substring "an" 6 times. Write a program that takes two lines of input, we call the first needle and the second haystack. Print the number of times that needle occurs as a substring of haystack."</p> <p>my solution (which works) is: </p> <pre><code>first = str(input()) second = str(input()) count = 0 location = 0 while location &lt; len(second): if location == 0: location = str.find(second,first,0) if location &lt; 0: break count = count + 1 location = str.find(second,first,location +1) if location &lt; 0: break count = count + 1 print(count) </code></pre> <p>if you notice, i have on two separate occasions made the if statement that if location is less than 0, to break. is there some way to make this a 'global' condition so i do not have repetitive code? i imagine efficiency becomes paramount with increasing program sophistication so i am trying to develop good practice now. </p> <p>how would python gurus optimize this code or am i just being too nitpicky?</p>

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.
