Which of the following is NOT a strength of monetary policy?

Assume the variable myWord references a string. Write a statement that uses a slicing

givi [52]

Answer:

"myWord[-5:]"

Explanation:

So whenever you slice a string, the syntax in python is expressed as:

string[a:b:c]

where a=start index (this is included in the sliced string)

b = end index (this is excluded from the sliced string)

c = increment

If any of these are included, they are set to default values, where a=0, b=len(string), and c=1.

The increment isn't necessary here, and it's just so you know the syntax a bit more

Anyways, I'm assuming when the question asks to display "the last 5 characters in the string" it means in order? e.g "abcdefghijk" -> "ghijk" and not "abcdefghijk" -> "kjihg"

The last piece of information to know is what a negative index represents.

For example if I have the piece of code

"

string = "hello world"

print(string[-1])

"

This will output "d", and the negative 1 represents the last letter. If you did -2, it would output the 2nd to last letter and so on.

So to print the last 5 characters, we simply use the -5 as the starting index.

"

string = "hello world"

print(string[-5:])

"

This will print "world" or in other words, the last 5 letters. The reason for this is because the -5 in the first spot means the starting index is the 5th to last letter, and when you have the : after the -5, this is the way of telling python you're slicing the string, and not indexing 1 character. You don't need to include another value after that, because it will default to the last index of the string, or more specifically the last index + 1, since the last index is still included.

So the last thing to know, is that if the string isn't greater than 5 characters, it just prints the entire string, and no errors are raised. You can test this out your self as well. So whenever you have a string that's less than 5 characters the entire string is outputted.

Provide a brief, high-level description of how the Internet’s connection-oriented service provides reliable transport.

mario62 [17]

Answer:

Connection-oriented is the method which is implemented in the transport and data link layer. It is basically depend upon the physical connection in the network system.

Transmission control protocol (TCP) is the connection oriented and user datagram protocol (UDP) is the connection less network transport layer. The TCP and UDP both are operate in the internet protocol (IP).

It basically require connection and it can be establish before sending data. This is also known as reliable network connection service. The connection oriented service establish connection between the different connection terminal before sending any data or information. It can easily handle traffic efficiently.

#Prompt the user to enter the miles.

Miles = float(input('Enter the miles to convert into kilometer: '))

#Check the miles.

if Miles >= 0 :

#Convert the miles to kilometers.

Miles_To_km = Miles*1.6

#Display the result.

print (Miles, "miles equivalent to", Miles_To_km, "kilometer.")

#Prompt the user to enter the gallons.

Gallon = float(input('Enter the gallons to convert into liter: '))

#Check the validity of the Gallons entered.

if Gallon >= 0:

#Convert gallons into liters.

Gal_To_Lit = Gallon*3.9

#Display the result.

print (Gallon, "gallons equivalent to", Gal_To_Lit, "liters.")

#Prompt the user to enter the pounds.

Pound = float(input('Enter the pounds to convert into kilograms: '))

#Check the validity of the Pounds entered.

if Pound >= 0:

#Convert pounds into kilograms.

Pounds_To_Kg = Pound*0.45

#Display the result.

print (Pound, "pounds equivalent to", Pounds_To_Kg, "kilograms.")

#Prompt the user to enter the temperature in Fahrenheit.

f = float(input('Enter the temperature in Fahrenheit: '))

#Check the value to be not greater than 1000.

if f < 1000:

#Convert Fahrenheit into celsius.

F_To_C = (f -32)*5/9

#Display the result.

print (f, "Fahrenheit equivalent to", F_To_C, "celsius.")

#Otherwise.

else:

#Display the error message.

print ("Invalid temperature (greater than 1000) !!!")

else:

#Display the error message.

print ("Pounds cannot be negative !!!")

else:

#Display the error message.

print ("Gallons cannot be negative !!!")

else:

#Display the error message.

print ("Miles cannot be negative !!!")

What does module in Python do? How to install it? Thanks!

lyudmila [28]

A Python module is an extension file which contains programmable resources for a given translation unit. This is very much like a header file in C and C++, it's modularized data. For example, say I wanted to write a server/client script. I can't easily do so with Python out of the box. I would require the "socket" module which contains all of the functions, variables and data structures which allow for network programming.

network.py
___________
from socket import *

s = socket(AF_INET, SOCK_STREAM)
(...)
