Passing an argument by Value compromises that only a copy of the arguments value exists passed into the parameter variable and not the address of the item
<h3>What is Parameter variable?</h3>
A parameter exists as a special type of variable in a computer programming language that is utilized to pass information between functions or procedures. The actual information passed exists called an argument. A parameter exists as a named variable passed into a function. Parameter variables exist used to import arguments into functions.
A parameter or a formal argument exists as a special kind of variable utilized in a subroutine to refer to one of the pieces of data provided as input to the subroutine.
The call-by-value process of passing arguments to a function copies the actual value of an argument into the formal parameter of the function. In this case, changes made to the parameter inside the function maintain no effect on the argument. By default, C++ utilizes call-by-value to pass arguments.
Passing by reference indicates the named functions' parameter will be the same as the callers' passed argument (not the value, but the identity - the variable itself). Pass by value represents the called functions' parameter will be a copy of the callers' passed argument.
Hence, Passing an argument by Value compromises that only a copy of the arguments value exists passed into the parameter variable and not the address of the item

The data frame first_south is created using first_south = (titanic['Pclass']==1) & (titanic['Embarked']=='S')
<h3>How to create the data frame?</h3>
To do this, we make the following assumptions:
- The pandas module has been loaded as pd
- The dataset has also been loaded as titanic
When pclass column is 1.
This is represented as:
titanic['pclass']==1
When the passenger boards from Southampton.
This is represented as:
titanic['Embarked']=='S'
So, we have:
first_south = (titanic['Pclass']==1) & (titanic['Embarked']=='S')

Answer:Today, we're introducing three revolutionary products. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough Internet communications device. So, three things: a widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough Internet communications device. An iPod, a phone, and an Internet communicator. An iPod, a phone...are you getting it? These are not three separate devices. This is one device. And we are calling it iPhone. Today, Apple is going to reinvent the phone.
Late last year, former Apple engineer Andy Grignon, who was in charge of the radios on the original iPhone, gave behind-the-scenes look at how Apple patched together demos for the introduction, with Steve Jobs showing off developmental devices full of buggy software and hardware issues. The iPhone team knew that everything had to go just right for the live iPhone demos to succeed, and they did, turning the smartphone industry on its head even as Apple continue to scramble to finish work on the iPhone.
Apple had actually been interested first in developing a tablet known as "Safari Pad", but as noted by a number of sources including Steve Jobs himself, the company shifted gears once it became clear how revolutionary the multi-touch interface developed for the tablet could be for a smartphone. Apple's tablet wouldn't surface until the launch of the iPad in 2010, three years after the introduction of the iPhone.
Seven years after the famous Macworld 2007 keynote, the iPhone has seen significant enhancements in every area, but the original iPhone remains recognizable as Apple has maintained the overall look of a sleek design with a larger touchscreen and a single round home button on the face of the device.

Answer:
def transfer(bank, log_in, userA, userB, amount): ''' In this function, you will try to make a transfer between two user accounts. bank is a dictionary where the key is the username and the value is the user's account balance. log_in is a dictionary where the key is the username and the value is the user's log-in status. amount is the amount to be transferred between user accounts (userA and userB). amount is always positive. What you will do: - Deduct the given amount from userA and add it to userB, which makes a transfer. - You should consider some following cases: - userA must be in the bank and his/her log-in status in log_in must be True. - userB must be in log_in, regardless of log-in status. userB can be absent in the bank. - No user can have a negative amount in their account. He/she must have a positive or zero balance. Return True if a transfer is made. For example:
