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():

fastest way to iterate dictionary python

# iterating through dictionary keys fast
dictKeys = list(nameOfDict.keys())

for i in range(len(dictKeys)):
  print(dictKeys[i])
  
  
# iterating through dictionary values fast
dictValues = list(nameOfDict.values())

for i in range(len(dictKeys)):
  print(dictKeys[i])

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)
