Is it possible to create a easy dictonary only one line?

Question

This question maybe is meaningless. We always create a list by only one line,like

Onelist = [ _ for _ in range(5)]

to create a list 0-4.

If I want to create a dictionary Result:

CountList = ["zero","one","two","three","four","five","six","seven","eight","nine"]
Result = {
    "zero":0,
    "one":0,
    # each value is zero
xxxxx
}

Is there a pythonic way to do this?

"We always create a list by only one line,like" No we don't. You would usually just use `list(range(4))` — juanpa.arrivillaga, Mar 13 '20 at 17:33

You can create dictionaries in the similar way you create lists using list comprehension:

CountList = ["zero","one","two","three","four","five","six","seven","eight","nine"]
Result = {count: 0 for count in CountList}

So if each value ``+5``,such as ``{'zero': 0, 'one': 5, 'two': 10 '......}``.What should I do? – Kevin Mayo Mar 13 '20 at 17:28

Do like this: {CountList[i]: i*5 for i in range(len(CountList))} – Sabareesh Mar 13 '20 at 17:30

Try:

Result=dict(zip(CountList, [0]*len(CountList)))

Outputs:

{'zero': 0, 'one': 0, 'two': 0, 'three': 0, 'four': 0, 'five': 0, 'six': 0, 'seven': 0, 'eight': 0, 'nine': 0}

Pretty straight forward: ```Result=dict(zip(CountList, range(0,5*len(CountList),5)))``` – Grzegorz Skibinski Mar 13 '20 at 19:26

That is quite simple:

dic={k:0 for k in CountList }

There's a function for that...

>>> dict.fromkeys(CountList, 0)
{'zero': 0, 'one': 0, 'two': 0, 'three': 0, 'four': 0, 'five': 0, 'six': 0, 'seven': 0, 'eight': 0, 'nine': 0}
