Understanding the Output

# D. Thiebaut
# Predict the output of the program below 

def main():
    a = 3
    degrees = 29
    pi = 3.14159
    name = "Julie"
    town = "Northampton"
    
    print( a, pi, name, town )

    input( ">" )

    print( "the temperature in", town, "is", degrees, "degrees" )
    
    input( ">" )

    print( "I love living in", town, "!" )

    input( ">" )

    print( "The temperature in ", town, "is", degrees, "!" )

    input( ">" )
    
    print( "the temperature in, say,", town, "isn't", degrees )

    raw_input( ">" )

    print( '"',",","',',","''",'",',",,'" )

    input( ">" )

    print( '"'+"+"+"'+',"+"+'"+'"-,'+"+,'" )

    input( ">" )

    print( '"'+"+"+"'+',"+"+'"+'"-,'+"+,'"*3 )

    input( ">" )

    x = input( "Enter a number between 0 and 10: " )
    y = input( "Enter another number between 0 and 10: " )
    print "x + y =", x+y

    input( ">" )

    x = input( ": " )
    y = eval( input( ": " ) )
    print( "x*y =",  x * y )
    
main()

Figuring out how to print

• Write a program that outputs this:

 *
 **

 ******
 *******

• Same question, but now this way:

• Or this way?
