Question

Implement the following function in the PyDev module functions.py and test it from a PyDev module named :

def wind_speed(speed):
    """
    -------------------------------------------------------
    description
    Use: category = wind_speed(speed)
    -------------------------------------------------------
    Parameters:
        speed - wind speed in km/hr (int >= 0)
    Returns:
        category - description of wind speed (str)
    ------------------------------------------------------
    """

Wind speeds are categorized as:

Wind speed (km/h)	Category
< 39	Breeze
39 - 61	Strong Wind
62 - 88	Gale Winds
89 - 117	Whole Gale
> 117	Hurricane

The function should return 'unknown' for a negative wind speed.

Sample testing:

Wind speed (km/h): 95
Category: Whole Gale

Answer 1

Make a module in PyDev in this manner:

1) Go to Window> Perspective> Open Perspective > PyDev(default)

2) Create a new package File> new > PyDev package

Check if .py files are associated with Python editor by going to: Windows> Preferences>General>Editors>File Asociations

3) Go to File> New> PyDev Module and fill module name

4) Press Finish

Here is the function:

def wind_speed(speed):

  if speed<39:

    category='Breeze'

  elif speed>=39 and speed<=61:

    category='Strong Wind'

  elif speed>=62 and speed<=88:

     category='Gale Winds'

  elif speed>=89 and speed<=117:

    category="Whole Gale"

  elif speed>117:

    category="Hurricane"

  elif speed<0:

    category="unknown"

  return category

For calling the function:

speed=int(input("Enter wind speed"))

print(type(speed))

category=wind_speed(speed)

print("Wind speed(km/h",speed)

print("Category:",category)

This will return the sample output:

Wind speed (km/h): 95
Category: Whole Gale
