I have a list of strings like this:
l = ['ABC, Apple, 20021015, 20030102', 'CDE, Graps, 20020506, 20030130']
I want to convert this list to a dictionary like
d = { 'ABC': 'Apple', 'CDE': 'Graps' }
So the key would be the first name in the string and the value would be the second name in the string.
This works in Python 2:
d = {j[0]:j[1] for j in [i.split(', ') for i in l]}
Output:
{'CDE': 'Graps', 'ABC': 'Apple'}
You could do it like this:
for index in range(len(l)):
line = l[index].split(", ")
d[line[0]] = line[1]
So, you split each entry by commas to get each name and date individually, and then you can add them each to the dict as normal.
Alternative, shorter form:
>>> dict(x.split(', ')[:2] for x in l)
{'ABC': 'Apple', 'CDE': 'Graps'}
This works by passing a sequence of two-element lists to dict() which then initializes the dictionary based on that sequence. The sequence being passed is this:
>>> [x.split(', ')[:2] for x in l]
[['ABC', 'Apple'], ['CDE', 'Graps']]
