1 A programmer is learning about subprograms. A program includes subprograms
to manipulate numbers and text. It prints out the contents of a data structure and
locates a substring in a quote. It does not function correctly.


Open file Q01.py


Amend the code to:
•
complete original line 16 to create a one-dimensional data structure,
implemented as a list, and initialise it with nine integers between 0 and 100,
inclusive. The integers can be in any order.
myList =
•
complete original line 19 to initialise a string variable to the quote:
Better a witty fool than a foolish wit
mySentence =
• fix the indentation error on original line 38
return (location)
•
complete original line 48 with a built-in function to find the length of the string
variable ‘mySentence’
end = mySentence)
• fix the syntax error on original line 51
while (location != -1)
• complete original line 55 with the keyword for selection
(location != -1):
• fix the syntax error on original line 57
print (FOOL + " found at location: " + str location)
• fix the NameError on original line 44
shwList (myList)
• fix the TypeError on original line 29
outString = outString + item + " "
• fix the logic error on original line 59 that causes an infinite loop.
start = location - 1
Do not add any additional functionality.
