Python Iterate Dict And Python Loop Through Dictionary

Each key is separated by a colon (:) from its value, items are separated by commas, and the whole thing is enclosed in a curved brace. An empty dictionary with no items is written with only two curly braces, such as: {}.

Keys are unique within a dictionary while values cannot be. The values of a dictionary can be of any type, but the key must be of an immutable data type such as strings, numbers, or tuples.

Access value in a dictionary
To access dictionary elements, you can use square brackets familiar with the key to get its value.

Python creates a dictionary using for loop

for i in user1:       # To check key in dictionary

    print(i)
To check all value presents in dictionary
for i in user1.values():
    print(i)

    OutPut = pramod
    Output  = 22

value method in Python iterate dict

Python dictionary value () method The python values () method is used to gather all values from a dictionary. It takes no parameters and gives a dictionary of values. If the dictionary has no value then it returns an empty dictionary. The syntax and examples of this method are given below. signature Values () Parameter No parameters The return It gives a dictionary of values. See some examples of the values () method to understand values. working capacity.

Python dictionary value() method example -1

This is a simple example that returns all values from the dictionary. An example is given below.

# Python dictionary value () method  

# Creating a Dictionary  

Inventory = {'fan': 200, 'bulb': 150, 'LED': 1000} 

 # Calling function  

Share = Inventory.values ()  

# Displaying Results 

Print ("stock available", share)

Output:

 Stock available {'Fan': 200, 'Bulb': 150, 'LED': 1000}

Python dictionary value () method example 2

If the dictionary is already empty, this method also returns an empty dictionary except for any errors or exceptions. See the example below.

# Python dictionary  value () method 

 # Creating a Dictionary  

Inventory = {} 

 # Calling function  

Share = Inventory.values ()

  # Displaying Results  

Print ("stock available", share)

Output:

 stock available {}

Python iterate dict value() method example 3

This example uses various methods such as length, keys, etc. to get information about the dictionary.

# Python dictionary value () method

  # Creating a Dictionary    

Inventory = {'fan': 200, 'bulb': 150, 'LED': 1000} 

# to work 

length = len(inventory) 

 Print ("Total number of values:", length)  

 Keys = Inventory.keys () 

 Print ("All keys:", key)  

Item = Inventory.items () 

 Print ("item:", Inventory)  

p = Inventory.popitem ()

print ("Deleted Items:", p) 

 Share = Inventory.values () 

 Print ("stock available", share)

Output:
Total number of values: 3 
All Keys: Tana_Key (['Fan', 'Bulb', 'Led']) 

Item: {'Fan': 200, {Bulb ': 150,: Led': 1000} 

Deleted Items: ('LED', 1000) 

Stock available {'Fan': 200, 'Bulb': 150}

Example -2

user_info_value = user_info.values()

user_info_value = user_info.values()
print(user_info_value

# OutPut = dict_values(['pramod', 22,'17691a05b9',
'B-Tech'])

example python loop through a dictionary

for i in user_info.keys():
    print(user_info[i])

      OutPut
pramod
2217691a05b9
B-Tech

      OR

user_info_value2 = user_info.keys()
print(user_info_value2)

  # OutPut = dict_keys(['name', 'age', 'rollno','class'])
