Question

1. Download the file(DATE LOCATED AT THE BOTTOM) for this laboratory exercise, then run the Python shell and enter the following commands:

>>> import date(located at the bottom)

>>> help( date )

>>> help( date.Date )

>>> x = date.Date()

>>> x

>>> print( x )

Consider the Python statements shown below. Using the output produced by the commands above, predict what the output will be, then test your predictions by executing the statements.

import date(located at the bottom)

A = date.Date( 1, 1, 2014 )

print( A )

print( A.to_iso() )

print( A.to_mdy() )

print( A.is_valid() )

print() B = date.Date( 12, 31, 2014 )

print( B ) print( B.to_iso() )

print( B.to_mdy() )

print( B.is_valid() )

print()

C = date.Date()

C.from_iso( "2014-07-04" )

print( C )

print( C.to_iso() )

print( C.to_mdy() )

print( C.is_valid() )

print()

D = date.Date()

D.from_mdy( "March 15, 2015" )

print( D )

print( D.to_iso() )

print( D.to_mdy() )

print( D.is_valid() )

print()

E = date.Date()

print( E )

print( E.to_iso() )

print( E.to_mdy() )

print( E.is_valid() )

print()

3. Revise the program(above) to test the behavior of the member function “__init__” when one or more of the arguments to that function are erroneous.

4. Revise the program(above) to test the behavior of the member functions “from_iso” and “from_mdy” when the arguments to those functions are strings which contains spaces.

5. Revise the program(above) to test the behavior of the member functions “from_iso” and “from_mdy” when the arguments to those functions are erroneous.
