For iterating over lists, tuples, dictionaries, and strings, Python also includes a special keyword: in. You can use in very intuitively, like so:

for number in range(5): print number, d = { "name": "Eric", "age": 26 } for key in d: print key, d[key], for letter in "Eric": print letter, # note the comma!
  1. In the example above, first we create and iterate through a range, printing out 0 1 2 3 4. Note that the trailing comma ensures that we keep printing on the same line.
  2. Next, we create a dictionary and iterate through, printing out age 26 name Eric. Dictionaries have no specific order.
  3. Finally, we iterate through the letters of a string, printing out E r i c.



For each key in my_dict: print out the key , then a space, then the value stored by that key. (You should use print a, b rather than print a + " " + b.)
