In this python tutorial we will learn How to Check If Element is Present in List Python with example. This post will give you a simple example of how to check if element is not present in list python. I would like to share with you how to find if an element is present in a list in python. Iâ€™m going to show you about python check if element in list exists. you will do the following things for python check if value in list exists.
If you want to check value exists or not in the python list then I will give you the following examples. we will use "in" with list for checking element exist or not.
Without any further ado, let's see the code examples below.
You can use these examples with python3 (Python 3) version.
# Created new List myList=[ "Hardik", "Vimal", "Harshad" ] # Key for check id exist or not elem="Hardik" # Checking elem exist or not in myList var if elem in myList: print("Given element is exist in List.") else: print("Given element is not exist in List.")
Given element is exist in List.
# Created new List myList=[ 1, 2, 3, 4, 5, 6 ] # Checking key exist or not in myList var for i in myList: if(i == 3): print("Given element is exist in List.")
Given element is exist in List.
# Created new List myList=[ 1, 2, 3, 4, 5, 6 ] # Checking key exist or not in myList var if (3 in myList): print("Given element is exist in List.") else: print("Given element is not exist in List.")
Given element is exist in List.

Discuss Beyonic API on slack
The Beyonic API is a representational state transfer, REST based application programming interface that lets you extend the Beyonic dashboard features into your application and systems, allowing you to build amazing payment experiences.
With the Beyonic API you can:
For usage, general questions, and discussions the best place to go to is Beyhive Slack Community, also feel free to clone and edit this repository to meet your project, application or system requirements.
To start using the Beyonic Python API, you need to start by downloading the Beyonic API official Python client library and setting your secret key.
Install the Beyonic API Python Official client library
>>> pip install beyonic
Setting your secrete key.
To set the secrete key install the python-dotenv modeule, Python-dotenv is a Python module that allows you to specify environment variables in traditional UNIX-like “.env” (dot-env) file within your Python project directory, it helps us work with SECRETS and KEYS without exposing them to the outside world, and keep them safe during development too.
Installing python-dotenv modeule
>>> pip install python-dotenv
Creating a .env file to keep our secrete keys.
>>> touch .env
Inside your .env file specify the Beyonic API Token .
BEYONIC_ACCESS_KEY = "enter your API "
You will get your API Token by clicking your user name on the bottom left of the left sidebar menu in the Beyonic web portal and selecting ‘Manage my account’ from the dropdown menu. The API Token is shown at the very bottom of the page.
import os import beyonic from dotenv import load_dotenv load_dotenv() myapi = os.environ['BEYONIC_ACCESS_KEY'] beyonic.api_key = myapi # Listing account: Working. accounts = beyonic.Account.list() print(accounts) #Listing currencies: Not working yet. ''' supported_currencies = beyonic.Currency.list() print(supported_currencies) Supported currencies are: USD, UGX, KES, BXC, GHS, TZS, RWF, ZMW, MWK, BIF, EUR, XAF, GNF, XOF, XOF ''' #Listing networks: Not working yet. """ networks = beyonic.Network.list() print(networks) """ #Listing transactions: Working. transactions = beyonic.Transaction.list() print(transactions) #Listing contact: Working. mycontacts = beyonic.Contact.list() print(mycontacts) #Listing events: Not working yet. ''' events = beyonic.Event.list() print(events) Error: AttributeError: module 'beyonic' has no attribute 'Event' '''
FROM python:3.8-slim-buster COPY . . COPY ./requirements.txt ./requirements.txt WORKDIR . RUN pip install -r requirements.txt CMD [ "python3", "getExamples.py" ]
Build docker image called demo
>>> docker build -t bey .
Run docker image called demo
>>>docker run -t -i bey
Now, I’ll create a Docker compose file to run a Docker container using the Docker image we just created.
version: "3.6" services: app: build: . command: python getExamples.py volumes: - .:/pythonBeyonicExamples
Now we are going to run the following command from the same directory where the docker-compose.yml file is located. The docker compose up command will start and run the entire app.
docker compose up
NB: The screenshot below might differ according to your account deatils and your transcations in deatils.
To stop the container running on daemon mode use the below command.
docker compose stop
