Monday (3/4/19)
Agenda:
- Confirm that you have completed and submitted the Count Vowels and Count Words repl.its
- Date Format Validation repl.it (no loops)
- You will define a function named checkDateFormat(dateStr) that takes a string as a parameter. Your function will return True if the date string is valid, and False otherwise
- A date string is valid if it adheres to the following rules:
- Must be in the format: MM/DD/YYYY
- MM must be a valid 2-digit month (01 -> 12)
- DD must be a valid 2-digit day (01 -> 31)
- YYYY must be a 4-digit number
- Guidance: You should use any and/or all programming strategies to help you define the function: checking the string length, string slicing, checking if specific characters are valid, etc.
- Submit to repl.it
- E-mail Harvester repl.it
- You will define a function named harvestEmail(s) that takes a string as a parameter. Your function will return the e-mail address within the string s
- Assume that the s parameter will have an e-mail address and all e-mail addresses have an @ symbol
- Use a loop to find the index of the @ symbol. Basically, check if each character is the @ symbol, and if it is, then remember the current index. Be sure to break out of the loop when you find the @ symbol
- Use a loop to find the index of the space " " character before the @ symbol (this is the beginning of the e-mail address). Hint: Start your loop counter at the index of the @ symbol, and count backwards/downwards. Be sure to break out of the loop when you find the space
- Use a loop to find the index of the space " " character after the @ symbol (this is the end of the e-mail address). Hint: Start your loop counter at the index of the @ symbol. Be sure to break out of the loop when you find the space
- Return the e-mail address by string slicing the indices of the beginning and end of the e-mail address
- Submit to repl.it
Thursday (2/28/19)
Agenda:
- Demonstrate Morse->Plain translator
- Run your Plain->Morse
- Copy the morse code and paste it back into Morse->Plain
- Complete the Count Vowels repl.it
- Complete the Count Words repl.it
Homework:
- Complete Count Vowels and Count Words if you did not finish in class
Tuesday (2/26/19)
Agenda:
- Morse Code updates
- Make sure both Part 1 and Part 2 of Morse Code Translator are complete
- Part 1 you can submit to repl.it
- Part 2 will have a repl.it submission soon...

- read()
- Integrate file reading into your morse code
Friday (2/22/19)
Agenda:
- Take the Strings Quiz in Canvas
- Closed-book, closed-note, closed-person
- Work on Morse Code Translator
- Complete Part 1: Plain -> Morse
- Repl.it auto-testing will be used to collect assignment
- Complete Part 2: Morse -> Plain (with a function)
- Challenge:
- Research Python dictionaries
- Re-implement both plain2morse.py and morse2plain.py so that they use dictionaries instead of functions

- Write a while loop that will continually ask the user to enter an angle while the number is not within the range
Agenda:
- Looping examples
- Acceptable ranges
- Generating non-overlapping coordinates
- While loops quiz on Friday (2/15/19)
Monday (2/11/19)
Warmup:
