+# Loops
+## For vs While Loops
+### For Loop
+- Really great when you want to iterate over something and you need to do something with each thing that you are iterating over.
+- Example:
+```
+fruits = ['Apple', 'Banana', 'Orange']
+for fruit in fruits:
+ print(fruit)
+
+for i in range(1, 6):
+ print(i)
+```
+### While Loop
+- Use while loop when you don't really care:
+ - what number in a sequence you are in, 
+ - which item you are iterating through in a list
+- You just want to simply carry out some sort of functionality many times until some sort of condition that you set.
+- While loops are a bit more dangerous since it can generate infinite loop: sort of condition that actually never becomes false!!!
+```
+while 5>3:
+ print('Yes') # this will print "Yes" until the end of time!
+```
