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 )
