What does send () do in Python?

The send() method returns the next value yielded by the generator, or raises StopIteration if the generator exits without yielding another value. When send() is called to start the generator, it must be called with None as the argument, because there is no yield expression that could receive the value.

How do you use yield in Python?

yield is a keyword in Python that is used to return from a function without destroying the states of its local variable and when the function is called, the execution starts from the last yield statement. Any function that contains a yield keyword is termed as generator. Hence, yield is what makes a generator.

How do you use Send in Python?

The send() method resumes the generator and sends a value that will be used to continue with the next yield . The method returns the new value yielded by the generator. The syntax is send() or send(value) . Without any value, the send method is equivalent to a next() call.

What is yield from in python?

"yield from" is available since Python 3.3! The yield from <expr> statement can be used inside the body of a generator. ... This iterator yields and receives values to or from the caller of the generator, i.e. the one which contains the yield from statement.

How do you send a message in a python socket?

Example – A TCP based Client:

1. clientSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM); # Connect to the server. clientSocket.connect(("127.0.0.1",9090));
2. # Send data to server. data = "Hello Server!"; clientSocket.send(data.encode());
3. dataFromServer = clientSocket.recv(1024); # Print to the console.

Why generators are used in Python?

Generator comes to the rescue in such situations. Python generators are a simple way of creating iterators. All the work we mentioned above are automatically handled by generators in Python. Simply speaking, a generator is a function that returns an object (iterator) which we can iterate over (one value at a time).

What is yield in Python with example?

Yield are used in Python generators. A generator function is defined like a normal function, but whenever it needs to generate a value, it does so with the yield keyword rather than return. If the body of a def contains yield, the function automatically becomes a generator function.

What is difference between yield and return in Python?

Yield is generally used to convert a regular Python function into a generator. Return is generally used for the end of the execution and “returns” the result to the caller statement. It replace the return of a function to suspend its execution without destroying local variables.

How does yield work?

yield is a keyword that returns from the function without destroying the state of it's local variables. When you replace return with yield in a function, it causes the function to hand back a generator object to its caller. In effect, yield will prevent the function from exiting, until the next time next() is called.

How do you send an automatic email in Python?

How to send emails using Python

1. Set up the SMTP server and log into your account.

How do I send an email using python stackoverflow?

1. If you use 2 Step Verification, you have to create an App specific password first and replace your normal password with it. ...
2. I agree, this is the best answer and should be accepted. ...
3. For python3, use: from email.mime.multipart import MIMEMultipart from email.mime.text import MIMEText – art Apr 16 '18 at 15:34.

What does send mean Python?

Resumes the execution and “sends” a value into the generator function. The value argument becomes the result of the current yield expression. The send() method returns the next value yielded by the generator, or raises StopIteration if the generator exits without yielding another value.
