python print value in dictionary code example

Example 1: printing python dictionary values

#print keys and values from the dictionary

for k, v in dic.items():
  print(k, v)

Example 2: python dict

# decleration
my_dict = {
  'spam': 'eggs',
  'foo': 4,
  100: 'bar',
  2: 0.5
}

# access single values from the dictionary
print(my_dict['spam']) # eggs
print(my_dict['foo']) # 4
print(my_dict[100]) # bar
print(my_dict[2]) # 0.5

# iterate over the dictionary
for key, value in my_dict.items():
  print(key, value)

# get length of the dictionary
print(len(my_dict)) # 4

# modify the dictionary
my_dict['baz'] = 'qux' # adds a pair
my_dict['baz'] = 'quxx' # also updates it
del my_dict['spam'] # removes a pair

# other methods
print(my_dict.copy()) # Returns a copy of the dictionary
print(my_dict.fromkeys('added', 100)) # Returns a dictionary with the specified keys and their values
print(my_dict.get('foo')) # Returns the value of the specified key
print(my_dict.items()) # Returns a list containing a tuple for each key value pair
print(my_dict.keys()) # Returns a list containing the dictionaries keys
print(my_dict.values()) # Returns a list of all the values in the dictionary
my_dict.setdefault('a', 'b') # Returns the value of the specified key. If the key does not exist: insert the key, with the specified value
my_dict.pop('foo') # Removes the element with the specified key
my_dict.popitem() # Removes the last inserted key-value pair
my_dict.update({'baz': 'val'}) # Updates the dictionary with the specified key-value pairs
my_dict.clear() # Removes all the elements from the dictionary

Example 3: how to print a value from a dictionary in python

dictionary={
  
    "Jeff":{
      	"lastname":"bobson",
        "age":55,
        "working":True
    },
  
    "James":{
      	"lastname":"Bobson",
        "age":34,
        "working":False
    }
}

# For a good format:

for i in dictionary:
    print(i, ":")
    for j in dictionary[i]:
        print("  ", j, ":", dictionary[i][j])
    print()
        

# Output:

Jeff :
   lastname : bobson
   age : 55
   working : True
   
James :
   lastname : Bobson
   age : 34
   working : False
    
# For just a quick reading:

for k, v in dictionary.items():
  print(k, v)
  
# Output: 

Jeff {'lastname': 'bobson', 'age': 55, 'working': True}
James {'lastname': 'Bobson', 'age': 34, 'working': False}
