#Write a program that prompts the user to enter one integer. The program 
#will do the following: if the input number is 1, the program will print 
#your name 3 times; if the input number is 2, the program will find the sum of 
#all even numbers between 0 and 10 inclusive, otherwise, the program will 
#print "I love Python language" 5 times. 

#Discussion: one input, integer, choice
#Calculations: if-elif-else and loop while. Three different tasks:
#1. printing name several times - loop while
#2. sum of all even numbers between 0 and 10 inclusive - loop while
#3. print "I love Python language" 5 times - loop while
