Exercise 8.x.1
Strings have a function called replace:
S.replace (old, new[, count]) -> string
Return a copy of string S with all occurrences of substring old replaced by new. If the optional argument count is given, only the first count occurrences are replaced.
Write a function removechars:
replacechars(old, new, string)
So that all characters in old get replaced by new in string, for instance:
replacechars("aeiou", "", "Tomato")
=>
Tmt
replacechars("aeiou", "*", "Tomato")
=>
T*m*t*
