I want to sort only VALUES of a dictionary but not KEYS . I have reversed the dictionary, so that's not an issue. I just want values to be sorted. Following is the code I've tried:
def reverse_dictionary(olddict):
newdict = {}
for key, value in olddict.items():
for string in value:
newdict.setdefault(string.lower(), []).append(key.lower())
for key, value in newdict.items():
newdict[key] = sorted(value)
return newdict
olddict=({'astute': ['Smart', 'clever', 'talented'],
'Accurate': ['exact', 'precise'],
'exact': ['precise'],
'talented': ['smart', 'keen', 'Bright'],
'smart': ['clever', 'bright', 'talented']})
result=reverse_dictionary(olddict)
print(result)
The output I got is:
{'keen': ['talented'], 'precise': ['exact', 'accurate'],
'exact': ['accurate'], 'bright': ['talented', 'smart'],
'clever': ['smart', 'astute'], 'talented': ['smart', 'astute'],
'smart': ['talented', 'astute']}
The VALUES are not sorted in the output. Please help.
You are returning the dictionary at the first loop iteration:
for key, value in newdict.items():
newdict[key] = sorted(value)
return newdict
Instead, you could just return new dictionary using dictionary comprehension:
return {k: sorted(v) for k, v in newdict.items()}
You are returning out of your second for loop to early
def reverse_dictionary(olddict):
newdict = {}
for key, value in olddict.items():
for string in value:
newdict.setdefault(string.lower(), []).append(key.lower())
for key, value in newdict.items():
newdict[key] = sorted(value)
return newdict
olddict=({'astute': ['Smart', 'clever', 'talented'],
'Accurate': ['exact', 'precise'],
'exact': ['precise'],
'talented': ['smart', 'keen', 'Bright'],
'smart': ['clever', 'bright', 'talented']})
result=reverse_dictionary(olddict)
print(result)
