Figure out the behavior of the programs below. Sketch their use of memory (scope) as the Python interpreter executes the program.
Exercise 1
def f1( a ):
print '-' * 40
print a
print '-' * 40
def f2( b ):
print "parameter = ", b
def main():
a = 3
b = 5
f1( a )
f2( a )
f1( b )
f2( b+a+10 )
main()
Exercise 2
def f1( a, b ):
print a, '-', b, '=', a - b
def f2( b, c ):
a = b + c
print 'a = ', a
def main():
a = 3
b = 4
c = 6
z = 10
f1( a, b )
f1( b, c )
f1( a+b, 3 )
f2( a, 4 )
main()
Exercise 3
def f1( a, b )
for i in range( b ):
print a,
print
def f2( a, b )
f1( '-', 20 )
f1( a, 10 )
f1( b, 5 )
def main( ):
f2( ' ', ' ' )
f2( 5, 6 )
f2( "hello", "there" )
main()
