• loops are used to iterate the condition
• loop are divided into two types
• for loop , while loop

while loop

• syntax
• initialization , condition , up dation

count = 1  # initialization 
while count <=10 : # conditon
print("print Hello")
count = count+1 

1 st program

• print number from 1 to 100

i = 1
while i == 100 :
print(i)
i = i+1

2nd program

• print numbers from 100 to 1

i = 100
while i >= 1 :
  print(i)
  i = i-1

3rd program

• print the multiplication table of a number n

n = int(input("enter the number : ", ))
i = 1 
while i <= 10 :
  print(n*i)
  i = i+1

4th program

• print the element of the following list using a loop
• [1,,4,9,16,25,36,49,64,81,100]

n = [1,4,9,16,25,36,49,64,81,100]
i = 0
while i <= len(n)-1:
  print(n[i])
  i = i+1
