''' Sequence Assignments '''

'''Extended Unpacking in action '''

'''Augmented Assignments'''

x = 1
x=x+1 # Traditional
print(x)

x += 1
print(x) #Augmented

'''Expression Statements'''

span(eggs,ham) #Function calls
spam.ham(eggs) #Method calls
spam          #printing variables in the interactive interpreter
print('a,b,c,sep=''') #printing operations in Python 3.0
yield x**2  # Yield expression Statements


''' Expression statements and in Place changes '''
L = [1,2]
L.append(3)
