?7-21 (remove.py) HTT9 Exercise 8, defining the function def squeeze (s,ch). Read the string s from the user, followed by the character ch to remove, then print out the result returned by squeeze (s,ch). [L7-3] (remove2.py) Same as the previous problem but do it for a list alist and element elt. That is, declare the function def squeeze_list (alist,elt) that returns a copy of the original list alist with each occurrence of element elt removed To read a list containing literals directly, read alist as a string. then "listify it" via eval (). Then read elt, finally printing out squeeze_list (alist,elt)
