comparing strings in array python

a = str('Hello') #Assigning variables
b = str('World')

if a == b: # Checking to see if they are the same 
  print('False')

                myArr[j],myArr[j + 1] = myArr[j+1], myArr[j]
    return myArr

print(bubbleSort(myArr))
# remove casefold if not list is uniform
