The document contains 3 code snippets with questions about modifying or improving the code. The first asks to rewrite a for loop iterating through a string by index to iterate by item instead. The second asks to modify code reading a CSV file to avoid an error when the header is read. The third asks to update a list in-place without reassigning the variable.

1. 1. Given the for loop below that loops through a string by index, rewrite the code to loop through
the string by item so it prints the same thing as the original code. s= "This is quiz 4" for i in
range(len(s)): print(s[i])2. Modify the following code so that it does not throw an error when reading
the header of the file. f=open("file.csv","rrn) for line in f : vals=line.split(",")total=int(vals[3])+
int(vals[4])print("totalscorefor",vals[0],"and",vals[1],total) f.close0 file.csv homeTeam, vistingTeam,

Write code to update a list, orig_list, from ['This', 'is', 'my', 'list'] to ['This', 'is','a', 'list', with,'7',
'values'] without just reassigning the variable orig list to a new list object.
