#loop FOR 
#this examples will explain how range function works

print("range(10)")
for i in range(10):
	print(i)

print()
print("range(1,10)")
for i in range(1,10):
	print(i)

print()
print("range(1,10,3)")
for i in range(1,10,3):
	print(i)

#i in range(a,b) works the following way:
#i=a, a+1, ....b-1

#i in range(a,b,c)  works the following way:
#i=a, a+c, ...(a+k*c)<=(b-1)

print()
print("range(-5, 5, 2)")
for i in range(-5, 5, 2):
	print(i) 

#answer: i= -5,-3, -1, 1, 3
