Question

Write a function durdle_game(target) which takes in as an argument a single string that will be the target to guess, and lets the user attempt to guess the target word. Before their first guess, the function should print out how many letters are in the target word.

Each time the user makes a guess, the function will print out the result of the previous function to tell the user how close they are. If the user guesses correctly, then the game is over. Have the function return the number of guesses that it took the user to get the correct answer.

If the user guesses something that isn’t the correct length, or something that doesn’t consist only of lowercase letters, then the function should print out “Invalid guess.”. Don’t count invalid guesses towards the number of guesses the user took to get the correct answer.

Examples (text in bold is returned, text in red is user input.):

>>> durdle_game('trick')

Welcome to Durdle! The target word has 5 letters.

Enter a guess:touch

              GBBGB

Enter a guess:truck

              GGBGG

Enter a guess:trick

              GGGGG

Congratulations, you got it in 3 guesses!

Here is one possible approach, in pseudocode, with some steps at a high-level that would need to be broken down into sub-steps:

Print welcome message with number of letters in target

Initialize guesses to 0

Initialize done to false

Loop while not done

Prompt user for guess and read it in

If guess is correct length and all lowercase letters

Increment guesses

Initialize result to an empty string

Loop through each position in guess and target

If guess letter is same as target letter

Add ‘G’ to end of result

Otherwise, add ‘B’ to end of result

Print result

If result does not have a 'B'

Set done to true

Otherwise, print invalid guess message

Print congratulations message

Return guesses

One Python technique that is useful for producing the result is to use the zip function inside a list comprehension to make tuples with one guess letter and one target letter for comparison to choose whether to have ‘G’ or ‘B’ in the result and then use the string function join to get back to a string from a list. For example:

>>> "".join([ 'G' if g == t else 'B' for (g,t) in zip("truck","trick")])
