问题:
I have an list of dictionary in Ansible config
myList - name: Bob age: 25 - name: Alice age: 18 address: USA
I write code as
- name: loop through debug: msg ="{{item.key}}:{{item.value}}" with_items: "{{ myList }}"
I want to print out like
msg: "name:Bob age:25 name:Alice age:18 address:USA"
How can I loop through this dictionary and get key and value pairs? Because it don't know what is the key. If I change as {{ item.name }}, ansible will work, but I also want to know key
回答1:
If you want to loop through the list and parse every item separately:
- debug: msg="{{ item | dictsort | map('join',':') | join(' ') }}" with_items: "{{ myList }}"
Will print:
"msg": "age:25 name:Bob" "msg": "address:USA age:18 name:Alice"
If you want to join everything into one line, use:
- debug: msg="{{ myList | map('dictsort') | sum(start=[]) | map('join',':') | join(' ') }}"
This will give:
"msg": "age:25 name:Bob address:USA age:18 name:Alice"
Keep in mind that dicts are not sorted in Python, so you generally can't expect your items to be in the same order as in yaml-file. In my example, they are sorted by key name after dictsort filter.

Here is your text: myList - name: Bob age: 25 - name: Alice age: 18 address: USA
Here is the Answer:
text='''myList - name: Bob age: 25 - name: Alice age: 18 address: USA'''
>>> final_text=''
for line in text.split('\n'): line1=line.replace(' ','').replace('-','') if 'myList' not in line1: final_text+=line1+' '
final_text 'name:Bob age:25 name:Alice age:18 address:USA '

class Person(object): def __init__(self, name, age, address): self.name = name self.age = age self.address = address def __str__(self): # String Representation of your Data. return "name:%s age:%d address:%s" % (self.name, self.age, self.address)
then you can have a list of objects you created. I am using some sample data here to create a list of dicts.
dict={"name":"Hello World", "age":23, "address":"Test address"} myList = [dict,dict,dict] objList = [] for row in myList: objList.append(str(Person(**row))) result = ' '.join(objList) print(result)
It ends out printing: name:Hello World age:23 address:Test address name:Hello World age:23 address:Test address name:Hello World age:23 address:Test address
I was going to do REPR but that is used a bit more differently, and i thought this might be better suited for your needs.
If you want to keep it really simple you can do this:
dict={"name":"Hello World", "age":23, "address":"Test address"} myList = [dict,dict,dict] objList = [] for row in myList; tmp = [] for k in row: tmp.append("%s:%s" % (k, row[k])) objList.append(" ".join(tmp)) print(" ".join(objList))
