Python Conditionals and Loops

A

100

Signifies that something is equivalent to something else

= =

200

Used to tell Python to skip the rest of the statements in the current loop block and to go on to the next iteration of the loop.

continue 

300

Repetition of instructions a specified number of times, or until a condition is met

Iteration

400

lets you ask a question to the program and only run code if the answer is true

If Statement

500

a = 25   

b = 40

Write an if/else statement to print two statements, one if a is greater than b and a second if it's not. Be sure to use correct format.

a = 25

b = 40

if a > b:

   print something

else:

   print something else

B

100

Known as counting loops

For Loops

200

A one-line statement that means "exit the current loop

break

300

the expression that decides whether the if statement or loop is going to continue being executed or not

condition

400

Ohappen when you make an error in the syntax of your program. Syntax errors are like making grammatical errors in writing.

Parse Error

500

Write a while loop for a variable called hungry that is equal to true.

The variable should print out that you need to eat..

hungry - true

while hungry:

    print("I need to eat")

    hungry = False

C

100

Known as conditional loops

while loops

200

Repeats code a fixed number of time

For Loop

300

Lets you enter just the starting and ending values, and it creates all the values in between for you.

range()

400

Your program executes but then stops due to some type of exception (something bad) happened

runtime error

500

Create a for statment to print a range of numbers between 1 and 7

for i in range(1,7):
    print i

D

100

A loop that never exits

Infinite Loop

200

Checks to see if loop_condition is True. If it is, it will loop again, if not, if false, loop will stop.

While Loop

300

Adding two strings together using the "+" operator 

concatenation

400

It will run successfully in the sense that the computer will not generate any error messages. However, your program will not do the right thing. It will do something else

Semantic Error

500

Create an if statement for an input statement called season asking the user to enter their favorite season.  If there favorite season is summer, print let's go swimming, if there favorite season is spring, print everything is turning green, if there favorite season is not one of the above, print I prefer the warmer weather.

season = input("What is your favorite season")

if season == "summer":

    print let's go swimming,

if season == "summer":

    print ("Let's go swimming!")

elif season == "spring":

    print ("Everything is turning green!"),

else:

    print ("I prefer the warmer weather")

E

100

Used to countdown by 1 in a loop

count -= 1

200

A control flow tool used as a second condition check after an if statement.

elif

300

Control structure that lets us do either one section of code or another depending on a test

If Else Statement

400

Caused almost always when you have used a variable before it has a value.

Name Error

500

Occurs when you you try to combine two objects that are not compatible.

For example you try to add together an integer and a string.

Type Error
