python loop through dictionary

dictionary = {52:"E",126:"A",134:"B",188:"C",189:"D"}
for key, value in dictionary.items():
	print(key)
	print(value)

python iterate through dictionary

a_dict = {'apple':'red', 'grass':'green', 'sky':'blue'}
for key in a_dict:
  print key # for the keys
  print a_dict[key] # for the values

loop through list of dictionaries python

dataList = [{'a': 1}, {'b': 3}, {'c': 5}]
for dic in dataList:
    for key in dic:
        print(dic[key])

python Looping through all values dictionary

fav_numbers = {'eric': 17, 'ever': 4}
for number in fav_numbers.values():
	print(str(number) + ' is a favorite')

python loop through dictionary

new_list = [something(key, value) for key, value in a_dict.items()]

python loop through dictionary

d = {'x': 1, 'y': 2, 'z': 3} 
for key in d:
    print key, 'corresponds to', d[key]

list to dictionary python using for loop

list1 = [1,2,3,4]
list2 = ['one','two','three','four']

#Single List convert to Dict
my_Dict = dict()
for index, value in enumerate(list1):
    my_Dict[index] = value
print(my_Dict)

# Two list convert to dict
new_dict = dict(zip(list1,list2))
print(new_dict)

Iterating Through Dictionaries with For Loops

Titanic_cast = {
           "Leonardo DiCaprio": "Jack Dawson",
           "Kate Winslet": "Rose Dewitt Bukater",
           "Billy Zane": "Cal Hockley",
       }

print("Iterating through keys:")
for key in Titanic_cast:
    print(key)

print("
Iterating through keys and values:")
for key, value in Titanic_cast.items():
    print("Actor/ Actress: {}    Role: {}".format(key, value))

# output -
# Iterating through keys:
# Billy Zane
# Leonardo DiCaprio
# Kate Winslet

# Iterating through keys and values:
# Actor/ Actress: Billy Zane    Role: Cal Hockley
# Actor/ Actress: Leonardo DiCaprio    Role: Jack Dawson
# Actor/ Actress: Kate Winslet    Role: Rose Dewitt Bukater

looping over dictionary python

python = {
  "year released": 2001,
  "creater":"Guido Van Rossum"
}
for x in python.values():
  print(x)

for loop items dictionary in python

jjj = {'chuck': 1, 'fred': 42, 'jan': 100}
# If you want only the keys
for key in jjj:
    print(key)
# if you want only the values
for key in jjj:
    print(jjj[key])
# if you want both keys and values with items
# Using the above you can get either key or value separately if you want
for key, value in jjj.items():
    print(key, value)

python loop dictionary

for key, value in d.items():
