Exercise 7.1.3 should be simplified

[JeltevanBoheemen]

Exercise 7.1.3 includes the lines:

first, *rest = list(words)
text = first
for word in rest:

Students are not familiar with this syntax and it should be replaced with:

text = words[0]
for word in words[1:]:

Also, parameter names word or characters make more sense since the function is invoked with a single word.

Is it really a problem that the students don't know the syntax? I vaguely recall going over this exercise in May. The students asked about it and some were able to guess what it meant. I explained it to the rest of the students. We were able to move on without much fuss.
