Loop Through Dictionaries

Loop Through Dictionaries

A plain for loop gives you the keys; other methods give you more.

Loop keys

thisdict = {"brand": "Ford", "model": "Mustang", "year": 1964}
for x in thisdict:
    print(x)  # brand, model, year

Loop keys explicitly

for x in thisdict.keys():
    print(x)

Loop values

for x in thisdict:
    print(thisdict[x])

Or use values():

for x in thisdict.values():
    print(x)

Loop both key and value

for x, y in thisdict.items():
    print(x, y)

TL;DR

• for k in d iterates keys.
• for k in d.keys() is explicit.
• for v in d.values() iterates values.
• for k, v in d.items() iterates both.
