Python 3.3 Dictionaries

Dictionaries是字典的意思，可以透過代碼找到值，但是代碼不能重複

import builtins


#key, value
d = {'a':1, 'b':2}

#dir
print("dir\n", dir(d))

#length
print("\n\nlength:",len(d))

#print value
print("value", d['a'])
#get value
print("get value", d.get('a'))

#print key and value
for k,v in d.items():
 print(k, " ,", v)

#clear
print("Clear:", d.clear())

print("length:",len(d))
