Enter a python error message, and the example code that caused that error.

week = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]
day_of_week = int(raw_input("Please give a day of week (0-6) 0 is Sunday."))
if day_of_week == 0 or day_of_week == 6:
    print "It is %d, sleep in." % week day_of_week]
else:
    print "It is %f, go to work." % week[day_of_week]

Produces this error:

$ python day_of_week.py 
  File "day_of_week.py", line 4
    print "It is %d, sleep in." % week day_of_week]
                                                 ^
SyntaxError: invalid syntax

week = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"]

day_of_week = int(raw_input("Please give a day of week (0-6) 0 is Sunday."))
print "It is %s." % week(day_of_week)

produces this error when a day of the week (number) is entered

# Tip calculator 2

bill = float(raw_input("What is the total bill amount? "))
service = raw_input("What is the level of service? (good, fair, or bad) ")
split = int(raw_input("Split how many ways? "))
good = .20
fair = .15
bad = .10

if service == "good":
    tip = good * bill
elif service == "fair":
    tip = fair * bill
elif service == "bad":
    tip = bad * bill
else:
    print "Try again later and choose a level of service between good, fair and bad"

print "Tip amount is: $.2f" % tip
print "Total amount is: $%.2f" % (tip + bill)
print "Amount per person is: $%.2f" % ((tip + bill) / split)

Gets this error:

SyntaxError: invalid syntax

bill = float(raw_input("How much was the bill? "))
service = str.upper(raw_input("How was the service (Good, Bad, OK)? "))
customer = float(raw_input("Split how many ways? "))

if service == "GOOD":
    print "Tip amount is $%.2f."  ((bill * .20))
    print "Total is $%.2f." % ((bill + (bill * .20)))

    print "Total is $%.2f." % ((bill + (bill * .15)))
    print "Amount per person: $%.2f." % ((((bill + (bill * .20))) / customer))

My convoluted code, missing the % in the first line of the if print statement, returns this error:

 python tip_calc2.py 
How much was the bill? 20
How was the service (Good, Bad, OK)? good
Split how many ways? 5

name = raw_input("what is your name? ".upper()).upper()

day_of_week = int(raw_input("Please give a day of week (0-6) 0 is Sunday.  "))
