What is the difference between a for loop and a while loop?

• A for loop repeats commands a specific number of times and a while loop repeats until a condition becomes false.

• A for loop is used to make decisions between two options and a while loop is used to make decisions between 3 options or

  more.

• A for loop is used when the variable is less than 10 and a while loop is used when the variable is 10 or greater.

• A for loop is used when we only need to meet one condition and a while loop is used when there are two or more conditions.

What would the output of the following code be?

x = "hello"

print x*3

• hello3

• hello hello hello
