Wednesday (3/6/19)
Warmup:
- Write a function named isDigit(ch) that returns True if the string ch is a digit character, and False otherwise
- Submit your solution to the repl.it for warmup credit
Agenda:
- Date Format Validation cont'd
- If you have not completed Date Format Validation already, then you can use isDigit() to help you
- Complete E-mail Harvester
- E-mail Harvester Challenges:
- Modify e-mail harvester so that it reads from a file
- Modify e-mail harvester so that multiple e-mails can be found/printed
- Test the file reading, multiple e-mail harvester by processing the HTML from some website
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, defining helper functions, 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
- Challenges:
- Modify e-mail harvester so that it reads from a file
- Modify e-mail harvester so that multiple e-mails can be found/printed
- Test the file reading, multiple e-mail harvester by processing the HTML from some website
