# Loops - For Loops
x = [1, 2, 7, 9, 10, 3, 14]
y = []
# x and y are lists

# Exercise 1
# -------------
# 1. Create a list of numbers. 2. Compute the squares for each number in the list. 3. Then print the list.
q = []
m = []
for each_n in range(1, 20, 3):
    q.append(each_n)   # my list of numbers 
    m.append(each_n*each_n)   # my list of numbers squared
    
#print ("q = ", q)
#print ("m = ", m)

# Exercise 2
# -------------
# Create a list of 20 numbers - [1,20]. If the number is even, print "Even". If the number is odd, print "Odd".
# [modulo operation] if number%2 == 0: then even, elif number%2 == 1, then odd.

for each_i in range (20):
    if each_i%2 == 0:
        pass
        #print ( each_i, 'is even.')
    elif each_i%2 == 1:
        pass
        #print ( each_i, 'is odd.')

# Exercise 3
# -------------
# while condition is true:
    # keep doing something
    # (have something that will change the condition later)

#count = 0
#while count < 5:
 #   print (count)
  #  count = count + 1    # count increased its value by 1

# Exercise 4
# ---------------
# Use a while/for loop to print this diagram. You will need to use if conditions also.
#         *
#         **
#         ***
#         ****

#solution #1
#x=0
#while x<20:
   # x = x + 1
    #print('x=',x)
 #   if x<=5:
      #  print('*')
 #   elif 5<x<=10:
      #  print('**')
  #  elif 10<x<=15:
      #  print('***') 
  #  elif 15<x<=20:
      #  print('****')
        
#solution #2
x=0
while x<20:
    x = x + 1
    #print('x=',x)
    if 4<x<=5:
        print('*')
    elif 9<x<=10:
        print('**')
    elif 14<x<=15:
        print('***') 
    elif 19<x<=20:
        print('****')
