how to print dictionary in python code example

Example 1: how to print something in python

print("whatever you want to print")

Example 2: printing dictionary in python

mydict = {'score1': 41,'score2': 23}
mydict['score3'] = 45

# key value pairs
for i in mydict:
    print(i,mydict[i])

Example 3: python print dictionary line by line

# Iterate over key/value pairs in dict and print them
for key, value in student_score.items():
    print(key, ' : ', value)

Example 4: python dictionary

#Creating dictionaries
dict1 = {'color': 'blue', 'shape': 'square', 'volume':40}
dict2 = {'color': 'red', 'edges': 4, 'perimeter':15}

#Creating new pairs and updating old ones
dict1['area'] = 25 #{'color': 'blue', 'shape': 'square', 'volume': 40, 'area': 25}
dict2['perimeter'] = 20 #{'color': 'red', 'edges': 4, 'perimeter': 20}

#Accessing values through keys
print(dict1['shape'])

#You can also use get, which doesn't cause an exception when the key is not found
dict1.get('false_key') #returns None
dict1.get('false_key', "key not found") #returns the custom message that you wrote 

#Deleting pairs
dict1.pop('volume')

#Merging two dictionaries
dict1.update(dict2) #if a key exists in both, it takes the value of the second dict
dict1 #{'color': 'red', 'shape': 'square', 'area': 25, 'edges': 4, 'perimeter': 20}

#Getting only the values, keys or both (can be used in loops)
dict1.values() #dict_values(['red', 'square', 25, 4, 20])
dict1.keys() #dict_keys(['color', 'shape', 'area', 'edges', 'perimeter'])
dict1.items() 
#dict_items([('color', 'red'), ('shape', 'square'), ('area', 25), ('edges', 4), ('perimeter', 20)])

Example 5: how to use dictionaries in python

student_data = {
  "name":"inderpaal",
  "age":21,
  "course":['Bsc', 'Computer Science']
}

#the keys are the left hand side and the values are the right hand side
#to print data you do print(name_of_dictionary['key_name'])

print(student_data['name']) # will print 'inderpaal'
print(student_data['age']) # will print 21
print(student_data['course'])[0]
#this will print 'Bsc' since that field is an array and array[0] is 'Bsc'
