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

import random
x = 0 + "babygurl"

  File "dc_exercise_guess_num.py", line 2, in <module>
    x = 0 + "babygurl"
TypeError: unsupported operand type(s) for +: 'int' and 'str'

First part of the tip_calc2.py code that I messed up:

total = float(raw_input("Total bill amount? "))
service = raw_input(("Level of service?  Good, fair, or bad? " )).low()
guests = float(raw_input("Split how many ways? "))

Spits this:

Total bill amount? 34
Level of service?  Good, fair, or bad? bad
Traceback (most recent call last):
  File "tip_calc2.py", line 2, in <module>
    service = raw_input(("Level of service?  Good, fair, or bad? " )).low()
AttributeError: 'str' object has no attribute 'low'

This code:

name = int("What is your name?")
print "Hello, %s!" / name

This error:

$ python hello.py
Traceback (most recent call last):
  File "hello.py", line 1, in <module>
    name = int("What is your name?")
ValueError: invalid literal for int() with base 10: 'What is your name?'

def guessingGame():
    my_random_number = random.randint(1, 20)

guess = 5

while guess > 0:

    guess =- 1
    myNum = int(raw_input("Whats the number?: "))
    if myNum == my_random_number:
        print "Yes! You win!"
        break
    if myNum > my_random_number:
        print "%d is too high" % myNum
        print "You have %d guesses left" % guess

    else:
        print "%d is too low" % myNum
        print "You have %d guesses left" % guess

print "You're out of guesses!"
print "Would you like to play again (Y or N)? "

again = raw_input().upper()

if again == "Y":
guessingGame()
else:
print "Bye!"

guessingGame()

output:

You have -1 guesses left
-bash: You: command not found
$ You're out of guesses!

> Would you like to play again (Y or N)?

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:

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

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

bad = .10

if service == "good":
    tip = good * bill

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:

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

 python tip_calc2.py
