Loops

100

What two loops have I taught you?

for loop and while loop

200

Write a for loop to loop through 0-4 and print them out

for i in range(5):

     print(i)

300

Write a while loop to loop backward through 0 to -3

i = 0

while i>=-3:

     print(i)

     i--

400

What do you use to leave a loop early?

break

500

Convert this to a for loop

i = 0

while i>-2:

     print(i)

     i--

for i in range(0, -2, -1):

     print(i)

Input/Strings

100

What do you use to take info from a user?

input()

200

Find the length of s and print it out

s = "yayyyy"

print(len(s))

300

check if s begins with hi and print the result

s = "hi buddy!"

print(s.startsWith("hi"))

400

Find the character at the last index of s and store it in a new variable

s = "hi hi hi"

c = s[len(s)-1]

500

What is the output when the user enters 6?

x = input("hi");

print(x/2)

The code causes an error to occur
