Look over Python assignment and answer one question.
Hi, I have attached both the assignment directions and a copy of my work so far. I wanted to make sure I was properly explaining the results. I also don't understand why the last print statement, print(2//3) has a result of zero instead of 8. Thanks so much.
Transcribed Image Text:Launch Python IDLE (an interactive Python session) and execute the following statements. Capture the
results in the Word document. Explain the results.
а.
print("Hello", "World!")
b.
print(3.0)
print(2.0 + 3.0)
С.
d.
print("2" + "3")
е.
print("2 + 3 =", 2 + 3)
f.
print(2 ** 3)
g.
print(2/3)
h.
print(2 // 3)
![In this week's module we downloaded Python IDLE, read the rules every developer needs to
know, practiced print statements, and created a python script file.
d. The print statement ("2" + “3") uses quotation marks to make each number a separate
string. The addition operator tells the program to put the two numbers together. The result
is 23
e. The print statement ( "2 +3 =", 2+3) has quotation marks around the first equation so it
is executed first. A comma puts a space between the two answers. The result is, 2+3 = 5.
f. The print statement (2**3) uses the exponential **, making the equation, 2 to the power
of 3. The result is, 8.
Problem 1- Execute the following statements.

а.
To execute the print statement, Hello World! ' quotation marks were used so the
program would know each word was a separate string and the comma separated the two
words. The result was, Hello World!

- I'm currently trying to work on a modified problem from C++ Engineering and Science (Chapter 7.2, Problem 4e). I've compiled the project and tried to run it, only to get -858993460 as an output. I don't know if this is a technical problem with the program I'm using (visual studio) or if I just did the program incorrectly, but I've been having these issues since I've first downloaded visual studio, and IDK how to properly fix them. I'll provide the instructions below this (with the modifications in bold), as well as the code I have. All I ask is to get some pointers on how to fix the code. Declare and initialize an array named Resistances that holds the following values: 16, 27, 39, 56, 81. You must also create additional arrays named Current, Voltage, and Power, each with the same size as the Resistances array. Set up a for loop to allow the user to enter the ‘current’ values to be stored in the array named Current when the program is run. (This must be able to accept decimal numbers).…arrow_forwardOne of the files is the instructions. One is what I have so far. My question's are: I'm confused about what they mean by holds the following data attributes. Do I write any code for that? ALSO: for list of number of gear teeth values- I'm not sure what they mean by should have a length equal to... etc. How would I write that in python? Thanksarrow_forwardIn C++, the first element of the array is referenced as array[0]. Explore the web and find the history of this choice. Some languages and packages like MATLAB start the indices from 1. That is, the first element of the array is referred to as array[1] not array[0]. If you were the creators of C++, which of the conventions for the array indices would you chose? Starting from 0 or 1.arrow_forward
