Hi, I am trying to teach myself Python and have a good book to help me
but I am stuck on something and I would like for someone to explain
the following piece of code for me and what it's actually doing.
Certain parts are very clear but once it enters the "def store(data,
full_name): ...." function and the "def lookup()..." function things
get a little confusing for me. Specifically, lines 103-108 *and* Lines
110-111.
Lastly, I am not sure how to print the results I've put into this
program either, the book I'm reading doesn't tell me. As you can tell,
I am a beginner and I don't truly understand everything that is going
on here...a lot, but not all....
Here is the code:
92 def init(data):
93 data['first'] = {}
94 data['middle'] = {}
95 data['last'] = {}
96
97 def store(data, full_name):
98 names = full_name.split()
100 if len(names) == 2: names.insert(1, '')
101 labels = 'first', 'middle', 'last'
103 for label, name in zip(labels, names):
104 people = lookup(data, label, name)
105 if people:
106 people.append(full_name)
107 else:
108 data[label][name] = [full_name]
109
110 def lookup(data, label, name):
111 return data[label].get(name)
112
113
114 MyNames = {}
115 init(MyNames)
116 store(MyNames, 'John Larry Smith')
117 lookup(MyNames, 'middle', 'Smith')
