# report message based on day of week
#       Sunday: weekend day
#       Monday: start of school week
#      Tuesday: school day
#    Wednesday: school day
#     Thursday: school day
#       Friday: end of school week
#     Saturday: weekend day

# get day of interest
reply = input( 'Enter day of week: ' )

# put day in standard format - first letter capitalized, others lower case
day = reply.strip() # get rid of leading / trailing whitespace
day = day.capitalize() # all characters are lowercase except the first character (uppercase)

# print( 'day:', day )
# day = reply.strip().capitalize()   # alternatively could also be written as

print( )

# analyze and report on day
# To Python, 'a' is not the same as 'A'.

# Check 7 Different Days

# if and elif have conditions / else does not have a condition

# if ( day == 'Monday' ):

# elif( day == 'Tuesday' ):
#     print( 'school day' )
# elif( day == 'Wednesday' ):
#     print( 'school day' )

#     print( 'weekend day' )
# elif( day == 'Sunday' ):
#     print( 'weekend day' )
# else: # not a day
#     print( 'That\'s not a day' )

# Commenting out multiple lines of code:
# Highlight the code

    # Windows: Ctrl /


# This is a gotcha!

# if ( ( day == 'Sunday' ) or ( day == 'Saturday' ) ): # RIGHT
#     print( 'weekend day' )

# if ( ( day == 'Sunday') or ('Saturday') ): # WRONG
#                           ^ This part is always True (it will always jump into the block)
# Same as doing if ( (day == 'Saturday') or True ):
    # Well one of them is true! So we always jump into this block!

# This is the same thing as doing
# if ('Saturday'):   # 'Saturday' will always be True! (just the string itself is True)
    # ...

if ( 'Monday' ): # 'Monday' as a string is ALWAYS True so we always print True
    print( True )
else: # We will never reach this code!
    print( False )

# 0 is always False
# 1 and any literal (strings, numbers, actual values) are always True by default!

# Computer science basically boils down to 0s and 1s.
# 0 is False
# 1 is True
# So basically when we evaluate these expressions, any literal value (like the string 'Monday')
# will always be True.
# If we have a test expression though (day == 'Monday') then this gets evaluated and then
# jumps into the block if that test expression / condition is True
