I am trying to figure out how to best create a python dictionary where the values are variable names
e.x.
ruleLst = ["gender brand","sport gender","sport gender brand"]
for i in ruleLst:
new_values = i.split(" ")
rules.update({i:new_values})
rules
returns:
{
'gender brand': ['gender', 'brand'],
'sport gender': ['sport', 'gender'],
'sport gender brand': ['sport', 'gender', 'brand']
}
What I try to output is:
{
'gender brand': [gender, brand],
'sport gender': [sport, gender],
'sport gender brand': [sport, gender, brand]
}
Where gender
, brand
, sport
are lists defined in the code before ruleLst
is defined.
CodePudding user response:
You can use list comprehension like:
ruleLst = ["gender brand","sport gender","sport gender brand"]
gender = ["M", "F"]
sport = ["basket", "volleyball"]
brand = [1, 2]
a = {i: [globals()[j] for j in i.split(" ")] for i in ruleLst}
print(a)
and output:
{
'gender brand': [['M', 'F'], [1, 2]],
'sport gender': [['basket', 'volleyball'], ['M', 'F']],
'sport gender brand': [['basket', 'volleyball'], ['M', 'F'], [1, 2]]
}

CodePudding user response:
Try using globals()[new_values[0]]
and globals()[new_values[1]]
instead of new_values
to get the variables value.
Like this:
ruleLst = ["gender brand","sport gender","sport gender brand"]
rules = {}
gender = ["male", "female"]
sport = ["basket", "volleyball"]
brand = ["x", "y"]
for i in ruleLst:
new_values = i.split(" ")
rules.update({i:[globals()[new_values[0]], globals()[new_values[1]]]})
print(rules)
CodePudding user response:
You could solve this with the map function like this. By casting it as a dict you'll get the dictonary you want.
rules = dict(map(lambda elem: [elem, elem.split(' ')], ruleLst))
