# Yixuan Sun # 9/20/2021 # I learn is sequence in python and how to fix it if there is an error # the problem is need to think more how I solve it is try out functions and figure out where i did wrong.

# put the print after the def then it will work # review and run code - note: fix error in the following "tasks" section have_hat = hat_available('green') # the hat is not define print('hat available is', have_hat) def hat_available(color): hat_colors = 'black, red, blue, green, white, grey, brown, pink' # return Boolean return(color.lower() in hat_colors)

# fist need to run the code that define hat available then call hat available def hat_available(color): hat_colors = 'black, red, blue, green, white, grey, brown, pink' return(color.lower() in hat_colors) have_hat = hat_available ('green') print('hat available is',have_hat)

# I create a program with tell which bird is in the program def bird_available(bird): bird_types = 'crow, robin, parrot, eagle, sandpiper, hawk, piegon' return bird.lower()in bird_types bird_input = bird_available(input("type bird name here:")) print("the bird is avaiable T/F: ", bird_input)

# the error is it did put definie so I put def infront of how many def how_many(): requested = input("enter how many you want: ") return requested number_needed = how_many() print(number_needed, "will be ordered")
