Question

Working with Python. I had to create a jackalope, with half an image of an antelope and half rabbit. Here is my code:

def animalCollage():
antelope = makePicture(pickAFile())
rabbit = makePicture(pickAFile())
antPixel = getPixels(antelope)
rabPixel = getPixels(rabbit)
  
for index in range(len(antPixel)/2,len(antPixel)):
newColor = getColor(rabPixel[index])
setColor(antPixel[index], newColor)

writePictureTo(antelope, "C:/Users/janin/OneDrive - Grand Canyon University/Grand Canyon University/CST-111/Week 6/jackalope.jpg")
jackalope = pickAFile()
show(antelope)

My code worked fine, but my instructor said: "the python code to create the jackalope looks fine except I can't run it because you tried to write the picture out to your hard drive. You need to write the picture out to a pickAFile() location."

I am not sure how to correct this. Can anyone please help?

Thank you

Answer

• The reason why this won't work on any other computer is that the location provided to writePictureTo() i.e. "C:/Users/janin/OneDrive - Grand Canyon University/Grand Canyon University/CST-111/Week 6/jackalope.jpg" only exists in your system. Other machines will not have the same structure and will fail to save the image.
• Solution:
  Input:
  filepicker.py

  import os #Import os library

  def pickAFile():

      filename = input("Enter a filename:\n") #Ask user to enter filename

      if os.path.exists(filename): #Check if file with the same name already exists

          os.remove(filename) #Remove the file

      open(filename, 'w+').close() #Create a new file

      return os.path.abspath(filename) #Return the file path

  path = pickAFile()

  print(path)
  
  Output:
  

• In the given code, we are creating a file in the current directory of the end machine.
• The function is returning a file path corresponding to the file.
• You can pass this file path to writePictureTo(antelop, path).
• Also, If you don't want the user to manually enter the filename, just replace " filename = input("Enter a filename:\n") " with " filename = "jackalope.jpg" ".
• If you already have a function with the same name, just change the name of this function to a suitable name.
