Small typos in chapter 2 of book3

[smp3142]

word *in* words*:*\ *print* word perhaps should be *for* word *in* words*:*\ *print* word

In Exercise 4 1 + 2 \* 5 The * is escaped and perhaps should just be 1 + 2 * 5

Thanks! will hit this with my upcoming edits.

@smp3142 I couldn't find the first typo you report. It looks correct to me in Chapter 2.

Note: the escaped * is in Chapter 2
