I want to replace keys of the dictionary present in python list using python only. I have this
Actual Data
[{'Title.1':'Replace key','number':'Replacing Keys','Title.1':'Replaced Keys'}]
Expected result
[{'Title':'Replace key','number':'Replacing Keys','Title':'Replaced Keys'}] In place of Title.1 I want Title
data = [{'Title.1':'Replace key','number':'Replacing
Keys','Title.1':'Replaced Keys'}]
for name, datalist in data.iteritems():
for datadict in datalist:
for key, value in datadict.items():
if key == Title.1:
datadict[key] = Title
print (data)
Basicly if you want to change a key you need to create a new key with the desired name copy the data of the old key in it then remove the old key so for that you can use this code :
my_dictionnary = { "old_key": "my_value" }
my_dictionnary["new_key"] = my_dictionnary["old_key"]
del my_dictionnary["old_key"]
So in order to answer to the specific case that you show us you can do something like this :
datas = [{'Title.1':'Replace key','number':'Replacing
Keys','Title.1':'Replaced Keys'}]
for data in datas:
for key in data:
if key[-2:] == ".1":
data[key[:-2]] = data[key]
del data[key]
Here same key given two times ...dictionary keys must be unique
for i in data:
for k,v in i.items():
if k=='Title.1':
del i[k]
i['Title'] = v
print(data)
#[{'number': 'Replacing Keys', 'Title': 'Replaced Keys'}]
