from math import radians, cos, sin, asin, sqrt 
def distance(lat1, lat2, lon1, lon2): 
	
# math contains a unit
# radians on the . function
# which converts angles from the degree system to the radius system

	lon1 = radians(lon1) 
	lon2 = radians(lon2) 
	lat1 = radians(lat1) 
	lat2 = radians(lat2) 
	
	# Haversine formula
	dlon = lon2 - lon1 
	dlat = lat2 - lat1 
	a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2

	c = 2 * asin(sqrt(a)) 
	
	# Earth's radius in kilometres.
	r = 6371
	
	# Earth's radius in kilometres.
	return(c * r) 
	
	
# Test
lat1 = 53.32055555555556
lat2 = 53.31861111111111
lon1 = -1.7297222222222221
lon2 = -1.6997222222222223
print(distance(lat1, lat2, lon1, lon2), "K.M")
