or this part of the assignment, you will create functions to calculate a person's body mass index (BMI). The formula you must use for this calculation is: BMI= (weight/height * height) **************Where weight is measured in kilograms and height is measured in meters. Do This: Write two functions: bmi() and imperial_bmi() that computes and returns the body mass index (BMI) of an individual. The first function - bmi takes the height and weight using metric measurements (centimeters and kilograms) and the second function (imperial_bmi) uses imperial measurements (inches and pounds). We will be using the auto-grader for this part of the assignment so your functions must match the specs precisely. Note: The BMI (metric) formula (given above) uses meters but our function for the bmi() takes centimeters as one of its parameters: bmi(height, weight): ''' Function -- bmi Takes as input height and weight in cm and kg and returns the BMI value Parameters: height (in cm) weight (in kg) Returns a float value representing the calculated bmi ''' imperial_bmi(height, weight): ''' Function -- imperial_bmi Takes as input height in inches and weight in pounds & returns the BMI value Parameters: height (in inches) weight (in pounds) Returns a float value representing the calculated bmi ''' Note: You do NOT need to provide a main() for this part of the assignment. You may write other "helper" functions if you wish (make sure you import any extra files you create AND include those files in your homework submission), but you must provide the bmi() and imperial_bmi() functions precisely as specified here. Note: You must use the measurement_conversion functions provided (you tested them thoroughly, right?). Hardcoding conversion values in your solution will result in marks being deducted from your grade.

For this part of the assignment, you will create functions to calculate a person's body mass index (BMI).
The formula you must use for this calculation is:
BMI= (weight/height * height)
**************Where weight is measured in kilograms and height is measured in meters.
Do This: Write two functions: bmi() and imperial_bmi() that computes and returns the body mass index (BMI) of an individual. The first function - bmi takes the height and weight using metric measurements (centimeters and kilograms) and the second function (imperial_bmi) uses imperial measurements (inches and pounds).
We will be using the auto-grader for this part of the assignment so your functions must match the specs precisely.
Note: The BMI (metric) formula (given above) uses meters but our function for the bmi() takes centimeters as one of its parameters:
bmi(height, weight):
'''
Function -- bmi
Takes as input height and weight in cm and kg and returns
the BMI value
Parameters:
height (in cm)
weight (in kg)
Returns a float value representing the calculated bmi
'''
imperial_bmi(height, weight):
'''
Function -- imperial_bmi
Takes as input height in inches and weight in pounds &
returns the BMI value
Parameters:
height (in inches)
weight (in pounds)
Returns a float value representing the calculated bmi
'''
Note: You do NOT need to provide a main() for this part of the assignment. You may write other "helper" functions if you wish (make sure you import any extra files you create AND include those files in your homework submission), but you must provide the bmi() and imperial_bmi() functions precisely as specified here.
