dictionary questions

[ljmetzger]

When you have a problem that has you confused, sometimes you can use Python as a tool to examine your data to give you a clue on how to proceed. For example, the following code may help you get a better feel for the data. Combined with the clues above, you should be able to solve the problem.

di2={'GR':'Greece','IT':'Italy','ES':'Spain'}
print(di2.keys())
print(di2.values())
print(di2['GR'])
print("")
for i in di2:
    print(i)
    print(di2[i])

print("")
di={'A':['a',41],'B':['b',42],'C':['c',43]}
print(di.keys())
print(di.values())
s=0
for i in di:
    print("")
    print(di[i])
    print(di[i][0])
    print(di[i][1])

Output:
dict_keys(['ES', 'IT', 'GR'])
dict_values(['Spain', 'Italy', 'Greece'])
Greece

ES
Spain
IT
Italy
GR
Greece

dict_keys(['B', 'C', 'A'])
dict_values([['b', 42], ['c', 43], ['a', 41]])

['b', 42]
b
42

['c', 43]
c
43

['a', 41]
a
