#LOOP WHILE in PYTHON
#loops are needed to perform repetition in the program
#Python supports two types of loops: WHILE and FOR

#Write a program that prints hello 5 times


i=0

while(i < 5):
	print("hello")
	i=i+1

print("i after loop", i)

#while loop condition is True, repeat statements 
#inside the loop (loop body)

#tracing the program
#i=0
#i<5 0<5 True hello will be printed and i=i+1, i =0+1=1, i gets value 1
#condition will be checked again i< 5 1<5 True hello will be printed, i=i+1=1+1=2
#condition will be checked again i< 5 2<5 True hello will be printed, i=i+1=2+1=3
#condition will be checked again i< 5 3<5 True hello will be printed, i=i+1=3+1=4
#condition will be checked again i< 5 4<5 True hello will be printed, i=i+1=4+1=5
#condition will be checked again i< 5 5<5 False LOOP IS TERMINATED

#iterations
#i - loop index, iterator
#each execution of the loop body statements is called  - iteration 

#This loop performed 5 iterations
