Q. Create a module lengthconversion.py that stores functions for various lengths conversion

·    miletokm()     to convert miles to kilometers

·   kmtomile()     to convert kilometers to miles

·   feettoinches()

·   inchestofeet() 

It should also store constant values such as value of (mile in kilometers and vice versa).
[I mile = 1.609344 kilometer ; 1 feet = 12 inches] 
Help( ) function should display proper information.

Answer :-

one_mille_in_km = 1.609344
one_feet_in_inche = 12

def miletokm(x)  :
    "Return value in kilometer from miles "
    return x * one_mille_in_km

def kmtomile(x) :
    "Return value in miles from kilometer "
    return x / one_mille_in_km

def feettoinches( x ):
    "Return value in inches from feet "
    return x / one_feet_in_inche

def inchestofeet(x) :
    "Return value in feet from inches "
    return x * one_feet_in_inche

Output :-

>>> import lengthconversion as l
>>> l.miletokm( 1000 )
1609.344
>>> l.miletokm( 45628 )
73431.14803200001
>>> l.kmtomile( 1000 )
621.371192237334
>>> l.kmtomile( 74873 )
46523.925276385904
>>> l.feettoinches( 1000 )
83.33333333333333
>>> l.feettoinches( 35524 )
2960.3333333333335
>>> l.inchestofeet( 1000 )
12000
>>> l.inchestofeet( 24232 )
290784
>>> help( l )
