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}
Python iterate dict

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'])
