get dictionary values python code example

Example 1: python get dict values as list

food_list=list(data.values())
print(food_list)

Example 2: python get value from dictionary

dict = {'color': 'blue', 'shape': 'square', 'perimeter':20}
dict.get('shape') #returns square

#You can also set a return value in case key doesn't exist (default is None)
dict.get('volume', 'The key was not found') #returns 'The key was not found'

Example 3: dict get list of values

list(d.values())

Example 4: get a value from a dictionary python

#!/usr/bin/python

dict = {'Name': 'Zabra', 'Age': 7}
print "Value : %s" %  dict.get('Age')
print "Value : %s" %  dict.get('Education', "Never")

Example 5: python dictionary access value by key

# Create a list of dictionary
datadict = [{'Name': 'John', 'Age': 38, 'City': 'Boston'},
 {'Name': 'Sara', 'Age': 47, 'City': 'Charlotte'},
 {'Name': 'Peter', 'Age': 63, 'City': 'London'},
 {'Name': 'Cecilia', 'Age': 28, 'City': 'Memphis'}]

# Build a function to access to list of dictionary
def getDictVal(listofdic, name, retrieve):
    for item in listofdic:
        if item.get('Name')==name:
            return item.get(retrieve)
          
 # Use the 'getDictVal' to read the data item
getDictVal(datadict, 'Sara', 'City') # Return 'Charlotte'

# -------------------
# to convert a dataframe to data dictionary
df = pd.DataFrame({'Name': ['John', 'Sara','Peter','Cecilia'],
                   'Age': [38, 47,63,28],
                  'City':['Boston', 'Charlotte','London','Memphis']})

datadict = df.to_dict('records')

Example 6: 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}
