I entered code from programming book "Python's Companion" about a bill calculator and although the script worked it returned a value of 111.78 when the book said the returned value should be 7.78 the code is correct exactly as typed when I looked at a variable with the id() function it returned a value that was not set in the variable declaration statement and I am not sure why
meal = 45 sales_tax = 7/100 tip = 20/100 meal += meal + meal * sales_tax bill = meal + meal * tipI am using Python 3.5.2 on Linux Mint 18.3 any help is appreciated?
