Hi
I'm learning how to code with python an I have purchased the book 'Python
Programming for the absolute beginner,third edition' by Michael Dawson.
There is one concept that is confusing me in chapter 3 page 71 there is a
program whose code I have pasted below. The author introduced a new way of
coding the Boolean NOT operator with the 'if' statement I have highlighted
the relevant area,apparently this if statement actually means if money !=
0,which I understood,but the program below this one which introduces the
idea of slicing also has a if statement similar to the first one,except the
second one accepts 0 value but the first one doesn't.
print("Welcome to the Chateau D'food")
print("It seems we are quit full today.\n")
money = int(input("How many dollars do you slip the Maitr D'? "))
*if money:*
print("Ah I think I can make something work")
else:
print("Please sit ,it may be a while")
input("\nPress enter to exit")
The slicing program
word = "existential"
print("Enter the beginning and ending index for the word existential")
print("press he enter key at 'Start' to exit")
start= None
while start != "":
start=input("\nStart: ")
* if start:*
start=int(start)
finish=int(input("Finish: "))
print ("word[",start, ":",finish, "]is " , end="")
print(word[start:finish])
input("\nPress enter to exit")
I hope i made sense.
Thankyou
