How to Check If Value Exists Or Not in Python Dictionary

In this python tutorial we will learn about How to Check If Value Exists Or Not in Python Dictionary with Example. you'll learn how to check if value is present or not in dictionary python. This tutorial will give you a simple example of python check value in dictionary exists. let us discuss about python check if values exists in dictionary. Let's get started with python dictionary value exists or not.

There are several ways to check value is exists or not in dictionary in python. i will give you two examples using if condition and using custom function in python.

So, without further ado, let's see simple examples:

Example 1:

main.py

user = {= {
  "ID": 1,"ID": 1,
  "name": "Hardik","name": "Hardik",
  "email": "hardik@gmail.com""email": "hardik@gmail.com"
}}
  
# Check value is present in dictionary# Check value is present in dictionary
if "Hardik" in user.values():if "Hardik" in user.values():
    print("value is exists.")print("value is exists.")
else:else:
    print("value is not exists.")print("value is not exists.")

Output:

value is exists.

Example 2:

main.py

user = {= {
  "ID": 1,"ID": 1,
  "name": "Hardik","name": "Hardik",
  "email": "hardik@gmail.com""email": "hardik@gmail.com"
}}

def checkValueExists(dic, key):def checkValueExists(dic, key):
    if key in dic.values():if key in dic.values():
        print("Present")print("Present")
    else:else:
        print("Not present")print("Not present")
         
# Check value is present in dictionary# Check value is present in dictionary
value = 'Hardik'= 'Hardik'
checkValueExists(user, value)(user, value)
 
# Check value is present in dictionary# Check value is present in dictionary
value = 'w'= 'w'
checkValueExists(user, value)(user, value)

Output:

Present
Not present

Working with Python dictionaries: a cheat sheet

Accessing, editing and looping through dictionary items

Dictionaries in Python are a collection of key-value pairs — meaning every item in the dictionary has a key and an associated value.

If we want to write down prices of some items in a grocery store, normally we will note them on a piece of paper like this:

eggs - 4.99
banana - 1.49
cheese- 4.5
eggplant - 2.5
bread - 3.99

In Python dictionary lingo, the name of each item is “key” and the associated price is “value” and they appear in pairs. We can represent the same in a Python dictionary data structure as follows:

{"eggs": 4.99,
"banana": 1.49,
"cheese": 4.5,
"eggplant": 2.5,
"bread": 3.99}

Notice the differences. In the dictionary

• each key is within quotation marks because they are strings
• the associated values are not quoted because they are numeric
• keys and values are separated by a colon (:)
• the items are comma-separated

Python any: How to Check If Element is Iterable or Not

An iterator is an object that contains the countable number of values.  Python iterator is an object that can be iterated upon, meaning that you can traverse through all the values inside an iterator.

Python any() Function

Python any() is an inbuilt function that returns True if any element of an iterable is True otherwise returns False. If the iterable object is empty, the any() returns False. The any() function is the opposite of  all() function.

Syntax

any(iterable)

Python any() method takes an iterable in Python. Those iterables are  Python List,  Python Dictionary, or  Python Tuple.
