book
for loop (2/5)

Remember data types we learned previously? for loop can easily iterate over some of them. For example, you can easily iterate over a string to get all symbols from it.


              
1234

            
# iterate over string
s = "small string"
for i in s:
  print(i)
copy

Or over list


              
1234

            
# iterate over list
l = [1, [2,3], 4, "wow"]
for i in l:
  print(i)
copy

The same applies to tuples.

Tâche

Swipe to start coding

Given list people. Using for loop, extract every single item from it.
