+'''There are some values in other data types that conditions will consider equivalent
+to True and False. When used in conditions, 0, 0.0, and '' (the empty
+string) are considered False, while all other values are considered True. For
+example, look at the following program:'''
+
+name = ''
+while not name:u
+  print('Enter your name:')
+  name = input()
+print('How many guests will you have?')
+numOfGuests = int(input())
+if numOfGuests:v
+  print('Be sure to have enough room for all your guests.')w
+print('Done')
+
+'''If the user enters a blank string for name, then the while statement’s condition
+will be True u, and the program continues to ask for a name. If the value for
+numOfGuests is not 0 v, then the condition is considered to be True, and the
+program will print a reminder for the user w.
+You could have typed not name != '' instead of not name, and numOfGuests
+!= 0 instead of numOfGuests, but using the truthy and falsey values can make
+your code easier to read.'''
