Deliverables

There is one deliverable for this assignment

hw6.py

Make sure the script obeys all the rules specified in the Script Requirements page.

Specification

Your script should ask the user for a minimum Celsius temperature and then a maximum Celsius temperature.

It should then print out a Celsius to Fahrenheit conversion table for this range of Celsius temperatures.

The table should have the same format as in homework 5.

This script must contain two functions

print_table_line
print_conversion_table

print_table_line

This function must have the following header

def print_table_line(celsius):

This function prints one line in the table.

The line consists of the Celsius temperature, a tab, and the Fahrenheit temperature.

It should print a line that looks like this

0   32

In order to do this, the function must first convert the Celsius temperature into a Fahrenheit value.

Both temperatures must be integers.

print_conversion_table

This function must have the following header

def print_conversion_table(min, max):

This function does four things

Prints the words "Celsius" and "Fahrenheit" to label the columns
Prints a line of dashes, -
Have a for loop
Call print_table_line(celsius) inside the loop

The for loop variable must range from the minimum Celsius temperature to the maximum Celsius temperature.

Each pass through the loop must call print_table_line(celsius) with a Celsius value.

Script for this assignment

Open a text editor
A program like Sublime.
Do not use Word or Notepad.

The following test code must be added to the bottom of your script

min = int(input("Please enter the starting temperature for the table: "))
max = int(input("Please enter the ending temperature for the table: "))
print()
print_conversion_table(min, max)

Save the file as hw6.py

Suggestions

Create the file hw6.py and add the header for the function print_table_line(celsius).
For the body of the function write print statement that simply prints the value of the celsius parameter.
Add the following statement after at the bottom of the script
```
print_table_line(30)
```
Run the code and fix any errors.
In print_table_line you need to convert celsius into into a Fahrenheit value.
Do this my adding an assignment statement about the print statement.
This statement should calculate Fahrenheit value and assign it to the variable fahrenheit.
Change the print statement so it print both the celsius and fahrenheit values.
Run the code and fix any errors.
Remove the print statement at the bottom of the script.
Below the first function, add the header for the print_conversion_table function.
There must be a blank line between the end of the previous function, and the header of the new one.
Add a print statement that prints the labels "Celsius" and "Fahrenheit".
Add a print statement that prints a line of dashes, -.
Add a blank line below this function.
Add the test code below to the bottom of your script.
Run the code and fix any errors.
Add a for loop will a loop variable that will run from the minimum to the maximum values given by the parameters.
In the for loop add a print statement that prints the loop variable.
Run the code and fix any errors.
Remove the print statement under the for loop.
In its place call the function print_table_line with the loop variable as the argument.
Run the code and fix any errors.
Adjust the print statement in print_table_line so the Celsius and Fahrenheit values line up with the labels printed by print_conversion_table.
Run the code and fix any errors.

Testing on Your Machine

Open IDLE.
Use the Open command in IDLE to open hw6.py
Run your script inside IDLE
Your output should look something like this
```
python3 hw6.pyPlease enter the starting temperature for the table: 10
Please enter the ending temperature for the table: 15
Celsius Fahrenheit
------------------
10      50
11      52
12      54
13      55
14      57
15      59
```
The text in blue is what you enter at the command line.

Be sure to run this script on the Unix machine so you know it works in the environment in which I will run it when I score your homework.

Unix Setup

Log in to users3.cs.umb.edu
You will be in your home directory.
Go to your it116 directory
```
cd it116
```
Go to your hw directory
```
cd hw
```
Create a directory for this exercise
```
mkdir  hw6
```
Check that the directory was created
```
ls
```

Copy the file to Unix

Open FileZilla and connect to users3.cs.umb.edu
You will have to connect using your Unix username and password.
Copy the file to the to it116/hw/hw6

Testing the script on Unix

Connect to
Use an ssh client.
Go to the directory for this exercise
```
cd  it116/hw/hw6
```
Run this script
```
python3 ex6.py
```

You should see something like

python3 hw6.pyPlease enter the starting temperature for the table: 10
Please enter the ending temperature for the table: 15
Celsius Fahrenheit
------------------
10      50
11      52
12      54
13      55
14      57
15      59

The text in blue is what you enter at the command line.

Be sure to run this script on the Unix machine so you know it works in the environment in which I will run it when I score your homework.

If your script does not run on users3 you will lose points

Testing

The following test code must be added to the bottom of your script

min = int(input("Please enter the starting temperature for the table: "))
max = int(input("Please enter the ending temperature for the table: "))
print()
print_conversion_table(min, max)

Your output should look something like this
