dictionary to list python

# This is our example dictionary
petAges = {"Cat": 4, "Dog": 2, "Fish": 1, "Parrot": 5}
# This will be our list, epmty for now
petAgesList = []
# Search through the dictionary and find all the keys and values
for key, value in petAges.items(): 
  petAgesList.append([key, value]) # Add the key and value to the list
print(petAgesList) # Print the now-filled list
# Output: [['Cat', 4], ['Dog', 2], ['Fish', 1], ['Parrot', 5]]

python dictionary to list

for key, value in dict.iteritems():
    temp = [key,value]
    dictlist.append(temp)

python dictionary to list

>> d = {'a': 'Arthur', 'b': 'Belling'}

>> d.items()
[('a', 'Arthur'), ('b', 'Belling')]

>> d.keys()
['a', 'b']

>> d.values()
['Arthur', 'Belling']

python list of dictionaries

  new_player1 = { 'firstName': 'LaMarcus', 'lastName': 'Aldridge', 'jersey': '12', 'heightMeters': '2.11', 'nbaDebutYear': '2006', 'weightKilograms': '117.9'}

python list of dictionaries to list

[d['value'] for d in l]

list of dict to dict python

single_dict = dict((k,v) for k,v in [item for subtup in list_of_dict for item in subtup])

list to dictionary

b = dict(zip(a[::2], a[1::2]))

turning list of dicts into dict of lists

#dictionary of lists to list of dictionaries:
v = [dict(zip(DL,t)) for t in zip(*DL.values())]
print(v)
# and back
v = {k: [dic[k] for dic in LD] for k in LD[0]}
print(v)

python list of dictionaries

lst = [{'a':0,'b':1,'c':2},
       {'d':3,'c':4,'b':5},
       {'a':5,'d':6,'e':1}]

print(lst[1])
print(lst[1]['c'])

python using list as dictionary key

# Declaring a dictionary
d = {} 
  
# This is the list which we are 
# trying to use as a key to
# the dictionary
a =[1, 2, 3, 4, 5]
  
# converting the list a to a string
p = str(a)
d[p]= 1
  
# converting the list a to a tuple
q = tuple(a) 
d[q]= 1
  
for key, value in d.items():
    print(key, ':', value)

create list of dictionaries from list of list python

list_of_dict = []
for row in list_of_list[1:]:	# Taking 0 index as header or key and rest as value
    list_of_dict.append({key: val for key, val in list(zip(*[list_of_list[0], row]))})

python list of dictionaries to list

[d['value'] for d in l if 'value' in d]
