# challenge #1
a = 3
b = 10
c = 20
print( "a =", a )
print( "b =", b )
print( "c =", c )
print( "sum =", a+b+c )



# challenge #2
word1 = "hello"
word2 = "there!"
print( word1, word2 )
print( word2, word1 )
print( word1, word1, word1 )
print( word1, word2, word2, word1 )

 
# challenge #3
print( word1 * 4, word2 )
print( word1, (word2+' ') * 5+ word1 )


# challenge #4
print( (word1+word2) * 5 )


# challenge #5
list = [ "Lea Jones", "Julie Fleur", "Anu Vias", "Anna Bell", "Lynn Grave" ]
for name in list:
    print( name )


# challenge #6
list = [ "Lea Jones", "Julie Fleur", "Anu Vias", "Anna Bell", "Lynn Grave" ]
for name in list:
    print( name )
    print( "-" * len( name ) )


# challenge #7
list = [ "Lea Jones", "Julie Fleur", "Anu Vias", "Anna Bell", "Lynn Grave" ]
for name in list:
    print( "-" * len( name ) )
    print( name )
    print( "-" * len( name ) )
    print()


# challenge of the Day
list = [ "Lea Jones", "Julie Fleur", "Anu Vias", "Anna Bell", "Lynn Grave" ]
for name in list:
    print( "--" + "-" * len( name ) + "--" )
    print( "|", name, "|" )
    print( "--" + "-" * len( name ) + "--" )
    print()
    

for name in list:
    print( "+-" + "-" * len( name ) + "-+" )
    print( "|", name, "|" )
    print( "+-" + "-" * len( name ) + "-+" )
    print()

Playing with semantics

• All these various loops print the same thing...

list = [ "Lea Jones", "Julie Fleur", "Anu Vias", "Anna Bell", "Lynn Grave" ]


#--- first loop example ---
for name in list:
    print( "+-" + "-" * len( name ) + "-+" )
    print( "|", name, "|" )
    print( "+-" + "-" * len( name ) + "-+" )
    print()

#--- separator ---
print( "\n" + "-"*80 + "\n" )


#--- second loop example ---
for name in list:
    noDashes = len( name ) + 2
    line     = '-' * noDashes 
    print( '+' + line + '+')
    print( '|' , name , '|' )
    print( '+' + line + '+')
    

#--- separator ---
print( "\n" + "-"*80 + "\n" )


#--- third loop example ---
for name in list:
    noChars  = len( name )
    noDashes = noChars + 2
    line     = '+' + '-'*noDashes + '+'
    print( line )
    print( '|' , name , '|' )
    print( line )
