If you have installed Python locally, launch JupyterLab by running:

conda activate sds

and

jupyter lab

Task 1 (5 points)

Write a function that checks the validity of a lon/lat pair based on their range. (i.e. longitude should be between -180 and 180, and latitude should be between -90 and 90). The function should return False if the pair is invalid, and True otherwise. The function should rely on two sub-functions is_lon_valid and is_lat_valid.

def is_lon_valid(lon):
    # complete the function
    return

def is_lat_valid(lat):
    # complete the function
    return

def is_lonlat_valid(lon, lat):
    # complete the function
    return

Test your function by running the following:

print(is_lat_valid(-186))

print(is_lon_valid(45))

print(is_latlon_valid(38.2, 0.8))

print(is_latlon_valid(270.3, -30.6))

Task 2 (5 points)

Write a function called convert_distance which converts between meters (m), kilometers (km), and miles (mi). It should handle all combinations. If in_unit == out_unit, just return the same value.

def convert_distance(area, in_unit, out_unit):
    # valid units: 'm','km','mi'
    
    # complete the function

    return converted_distance

Test your function by running the following:

print(convert_area(1000,'m','km'))

print(convert_area(100,'mi','km'))

print(convert_area(10,'km','mi'))

Task 3 (5 points)

  • a) Print the current local time in ISO 8601 standard format (i.e. YYYY-MM-DD hh:mm:ss)

  • b) Convert the string Jun 19, 2022 to ISO 8601 standard format

  • c) Convert the string 2022-06-19 220755 to ISO 8601 standard format (time order is hours, minutes, seconds)

  • d) What day of the week was it in Eugene when Unix time reached 1234567890 seconds?

  • e) What year will it be when Unix time reaches 2,000,000,000 seconds?

Important

Save your notebook to your local course folder and submit assignment (in .pdf format) to Canvas by the deadline.
