If, by mistake, they enter letters or punctuation signs, the conversion into an integer will fail and generate an exception (error) and the program would stop running.To validate the user entry and ensure that is a number it is possible to catch this exception when it occurs using the try…except…block as follows: See how we can use this approach to define our own function (called input Number()) to ask for a number.
In terms of workflow, after a user registers a new account, a confirmation email is sent. How about we update the current test suite since it’s, well, broken.
The user account is marked as “unconfirmed” until the user, well, “confirms” the account via the instructions in the email.
This is a simple workflow that most web applications follow.
One important thing to take into account is what unconfirmed users are allowed to do.
[block:api-header] [/block] This is a step-by-step tutorial of how the Yammer Server-Side OAuth 2.0 flow works: **A.
User Authentication** When the user clicks a “Sign in with Yammer” button on your app’s login page, the user should be redirected to Yammer’s OAuth 2.0 dialog at: [block:code] [/block] `client_id` and `redirect_uri` are available in the app that you registered.
If the user is not logged in, they will be prompted to enter their sign in credentials. App Authorization** Once Yammer has successfully authenticated the user, the OAuth 2.0 dialog will prompt the user to authorize the app.
If the user clicks “Allow”, your app will be authorized.
The OAuth 2.0 flow is typically initiated by a user clicking a “Sign in with Yammer” button on your app’s login page. **There are two OAuth 2.0 flows for Yammer:** *Server-Side Flow*: Referred to as “Authorization Code Grant” in the OAuth 2.0 Specification, the server-side flow should be used whenever you need to call the Yammer API from your web application server.
The end result is a token that your app will use to write activity (push data) to Yammer, and retrieve information from Yammer (pull data). *Client-Side Flow*: Referred to as “Implicit Grant” in the OAuth 2.0 Specification, the client-side flow should be used when you need to make API calls from a client, such as Java Script running in a web browser or from a native mobile or desktop application. User Authentication: Ensures that the user is who they say they are. App Authorization: Ensures that the user knows that they are allowing your app to access their data. App Authentication: Ensures that the user is giving their information to your app and not someone else’s app.
This new function can then be used instead of an input() function whenever we expect the user to enter a whole number.
