从.txt文件创建字典

Question

I have a .txt file with list of users, it goes like this:

ID - NAME(S) - LAST NAME(S) - LOGIN - PASSWORD

0001 - Juan Carlos - Botero Mora - jcboterom - snf23jn4

.

.

So, I need to create a dictionary like this:

{'0001': ['Juan Carlos', 'Botero Mora', 'jcboterom', 'snf23jn4']}

The code is

def dict():
with open('admins.txt', 'r') as document:
    answer = {}
    for line in document:
        if line.strip():
            key, value = line.split(None, 1)
            answer[key] = value.split()
return answer

But this is what I get:

{'0001': ['-', 'Juan', 'Carlos', '-', 'Botero', 'Mora', '-', 'jcboterom', '-', 'snf23jn4']

What's wrong?

Answer 1

All you need is to split the value again with the delimiter - rather than space.

>>> key, value = line.split('-', 1)
>>> answer[key] = value.split(' - ')
>>> answer
{'0001 ': [' Juan Carlos', 'Botero Mora', 'jcboterom', 'snf23jn4']}

From the python docs

str.split([sep[, maxsplit]]) Return a list of the words in the string, using sep as the delimiter string.

Answer 2

The issue is that you are splitting your strings at all whiteplaces , which is what str.split() does. Instead you should split them at '-' and then strip off the whitespace from the result.

Code -

def dict():
    with open('admins.txt', 'r') as document:
        answer = {}
        for line in document:
            if line.strip():
                key, value = line.split('-', 1)
                answer[key.strip()] = [v.strip() for v in value.split('-')]
    return answer

Demo -

>>> s = '0001 - Juan Carlos - Botero Mora - jcboterom - snf23jn4'
>>> key,value = s.split('-',1)
>>> answer = {}
>>> answer[key.strip()] = [v.strip() for v in value.split('-')]
>>> answer
{'0001': ['Juan Carlos', 'Botero Mora', 'jcboterom', 'snf23jn4']}

Answer 3

split() can go with pattern. Here you can use ' - '

>>> s = '0001 - Juan Carlos - Botero Mora - jcboterom - snf23jn4'
>>> s
'0001 - Juan Carlos - Botero Mora - jcboterom - snf23jn4'
>>> [key, value] = s.split(' - ', 1)
>>> key
'0001'
>>> value
'Juan Carlos - Botero Mora - jcboterom - snf23jn4'
>>> value = value.split(' - ')
>>> value
['Juan Carlos', 'Botero Mora', 'jcboterom', 'snf23jn4']
