whiile loops
1. Execute a set of statements for as long as a condition evaluates to true
for loops
1. Used for iterating over a sequence ( eg. list, tuple, dictionary, set, or a string )

This condition always evaluates to True, so will continue forever

i = 0
while True:
  i += 1
  print("keep going... " + str(i))

Adding a break key word, we can stop the loop

i = 1
while i <= 6:
  print(i)
  i += 1
  if i == 5:
    break

Adding a continue key word, we can do something and continue the loop

i = 1
while i <= 6:
  print(i)
  i += 1
  if i == 5:
    print("i equals 5")
    continue

Adding an else key word, we can do something else

i = 1
while i <= 6:
  print(i)
  i += 1
else:
    print("i is no longer less than 6")

Iterates over the list and prints the items, one line at a time

fruits = ["apple", "banana", "orange"]
for x in fruits:
  print(x)

Iterates over the letters in a string and prints them, one line at a time
```
for x in "banana":
  print(x)
```

Can use the break key word

fruits = ["apple", "banana", "orange"]
for x in fruits:
  print(x)
  if x == "banana":
    break

Can use the continue key word

fruits = ["apple", "banana", "orange"]
for x in fruits:
  print(x)
  if x == "banana":
    print("I love bananas!")
    continue

Can use the else key word only if the loop exits normally ( without a break )

fruits = ["apple", "banana", "orange"]
for x in fruits:
  print(x)
  if x == "apple":
    break
else:  
  print("I'm done!")
