IPP-DEV-03-002: A Temperature Conversion Function

[labbenchstudios]

Description

• Using instructions from the in-class lecture, update the SimpleTempConversion.py module with a Celsius to Fahrenheit conversion function.

Estimated effort may vary greatly

• The estimated level of effort for this exercise shown in the 'Estimate' section below is a very rough approximation. The actual level of effort may vary greatly depending on your development and test environment, experience with the requisite technologies, and many other factors.

Actions

Step 1: Make Sure Your System is Setup for Python and This Course

• See IPP-CFG-01-001

Step 2: REMINDER: Make Sure PYTHONPATH is Set Correctly

Whether running Python tests within your IDE or from the command line, you must set the PYTHONPATH environment variable in every execution environment (e.g., every terminal you launch) when attempting to run any of your scripts and their tests or the IPP test app from the command line. The IPP source and test paths will be as follows:

• {your IPP source code path}
• {your IPP source code path}/tests

See IPP-DEV-01-001 for details.

Step 3: Edit the SimpleTempConversion.py module you created in the previous exercise.

• Open the module, and implement the following test cases:

Test 1 (create two temperature conversion functions - F to C and C to F)

• Name one convertTempFtoC()
• Name the other convertTempCtoF()
• Here are the code examples:

def convertTempFtoC(tempInF: float = 0.0):
    '''
    Converts the passed in Farenheit temperature to Celsius.
    Returns the result as a float.

    Algorithm: C = 5/9 x (F - 32)

    '''
    # See if you can create this on your own.
    # You may want to use the round() function as follows:
    # round(some_number, 1)
    # This will round the value to a single decimal place

    # print the result - temp in F and temp in C
    
    # return the temp in C float value

def convertTempCtoF(tempInC: float = 0.0):
    '''
    Converts the passed in Celsius temperature to Farenheit.
    Returns the result as a float.

    Algorithm: F = C x (9/5) + 32

    '''
    # See if you can create this on your own.
    # You may want to use the round() function as follows:
    # round(some_number, 1)
    # This will round the value to a single decimal place

    # print the result - temp in C and temp in F
    
    # return the temp in F float value

• Test your converters to see if they work:

orig_f_val = 72.0
c_val = convertTempFtoC(orig_f_val)
f_val = convertTempCtoF(c_val)

print(f"Celsius = {c_val} and Farenheit = {f_val}. Original Farenheit is {orig_f_val}")

if (orig_f_val == f_val):
    print("The temp converter works!")
else:
    print("The temp converter failed!")

Estimate

• Medium

Tests

• From within your IDE

  • Right click on your newly created module SimpleTempConversion.py and click your IDE's run icon
  • You should see output similar to that discussed in class

• From the command line

  • Open a terminal and cd to your IPP_HOME path
  • Start your virtual environment (if not already running)
  • Be sure your PYTHONPATH is set correctly
  • Run the module
    • python ./labmodule03/SimpleTempConversion.py
  • You should see output similar to that discussed in class
