For

for I in range(0,7) 

String

loop through each character

for x in "banana": 
  print(x) 

List

loop through each item in the list

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

Exit The Loop

you can use the break statement

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

Nested Loops

The "inner loop" will be executed one time for each iteration of the "outer loop":

adj = ["red", "big", "tasty"] 
fruits = ["apple", "banana", "cherry"] 

for x in adj: 
  for y in fruits: 
    print(x, y) 

pass Statement

for loops cannot be empty, but if you for some reason have a for loop with no content, put in the pass statement to avoid getting an error.

for x in [10, 20, 30]: 
  pass
