Lab 6: string methods; working on REPL projects

Instructions

• Work with your partner for the collaborative REPL assignment.

• Review string subscripting, slicing and method examples below.

• Read and experiment with high-low word-guessing game.

  ---

1. Try these in the IDLE shell, in order, one at a time:

   >>> name = 'Ada Lovelace'
   >>> name
   
   >>> name.upper()
   >>> name.lower()
   >>> name.isupper()
   
   >>> upped = name.upper()
   >>> upped
   
   >>> upped == name
   >>> upped.lower() == name.lower()
   >>> upped.isupper()
   
   >>> help(name.islower)
   
   >>> name[0]
   >>> len(name)
   >>> name[len(name)-1]
   >>> name[-1]
   >>> name[12]
   >>> name[-12]
   >>> name[-13]
   
   >>> help(name.find)
   
   >>> name.find(' ')
   >>> name[0:3]
   >>> name[:3]
   >>> name[4:len(name)]
   >>> name[4:]
   >>> name[4:8].lower()
   
   >>> help(name.count)
   
   >>> name.count('')
   >>> name.count(' ')
   >>> name.count('a')
   >>> name.lower().count('a')
   
   >>> name.center(20)
   >>> name.center(20, '*')

2. From IDLE, Open the file high_low_word_guess.py from the high_low_word_guess folder. Read over the file.

3. Run the module in IDLE and then experiment with playing the game.

4. In the shell, experiment with accessing the words file:

    >>> our_file = open('wordle-words.txt')
    >>> type(our_file)
   
    >>> lots = our_file.read()
    >>> len(lots)
    >>> our_file.close()
   
    >>> lots[285:321]
