The code repeats twice. Which "for" loop would I use if I wanted to rewrite this code using a "for" loop? Options: for i in range(1), for i in range(3), for i in range(2):, Can not write it as a loop

Back

for i in range(2):

Answer explanation

The following code repeats twice:

turtle.forward(100)

turtle.left(90)

turtle.forward(50)

turtle.left(90)

The for loop for twice is:

for i in range(2)

which counts 0 and then 1 and stops

for i in range(3)
#print(i+1)

Back

What is the correct "for" loop to use? Options: from turtle import * for i in range(5): forward(50) right(90), from turtle import * for i in range(3): forward(50) right(90), from turtle import * for i in range(4): forward(50) right(90)

Back

from turtle import * for i in range(4): forward(50) right(90)

Answer explanation

a range(n) function goes 0 up to n but does not include n. Therefore, range(4) goes from 0 to 3 but does not include the 4. If you want it to run 4 times you need range(4).

What is the correct way to replace the code with a "for" loop? Options: for 'grok' in letter: print(letter), for letter in 'grok': print(grok), for letter in 'grok': print(letter), for 'grok': print(letters)

Back

for letter in 'grok':
print(letter)

Answer explanation

The correct syntax is:

for <where to store each letter> in <the word>

for letter in 'dog':

This will loop through each letter in the word dog.

What is the output of the following code?
word = 'cat' for letter in word: print("letter") Note: The output will print one letter per line
