6. Advice for the Tests
These things can make the difference of whether you pass or fail this class when studying
Go through each class days notes and example programs on the website
Practice coding over and over by going through your labs!!! This is the only way to really learn.
Review vocabulary and concepts by reading the book!!

7. Again…
The only way you can become comfortable with a toolset is to practice
Understanding what a power drill does will not help you much if you don’t practice using it
It’s the same for code
Practicing coding will make you more familiar with the coding structures necessary to code more quickly
Patterns will emerge, it will become easier

8. Review Wrap-Up Find a Letter Error Checking Nested Loops
DeMorgan’s Law
Using and/or/not correctly

9. Example Problem Can you write a program that
Prompts for a string and a letter
Searches that string for a letter (without using the .find() method!)
Prints a message saying in which index position the letter was found or that the letter was not found

10. 4.1 Find a Letter
string = input('Enter string: ') target = input('Input character to find: ') found = False for index in range(len(string)): #for each index if string[index] == target: #check print( "Letter found at index: ", index ) found = True break # stop searching if (found == False) print( 'Letter',target,'not found in',string)
