The document contains code snippets and explanations demonstrating various Python programming concepts like while loops, factorials, palindrome checking, reversing digits of a number, and jump statements like break and continue. It shows examples of printing squares of odd numbers from 1 to 100 using a while loop, calculating factorials of different numbers through iterative processes, checking if a number is a palindrome by comparing the reversed number to the original, and using break and continue statements to terminate or skip iterations in a for loop.

1. #printing natural nos and sum from 1 to 100 – while loop

2. #printing squares of odd nos fro 1 to 100
x=1
while x<=100:
print(x* x, end="t")
x+=2
print(" bye")

3. 56 63 70 77 84 91 98
sum of the nos divisible by 7 from 1 to 100 is : 539

4. n!=n*(n-1)*(n-2)*(n-3)……..1
5!=5*4*3*2*1
4!=4*3*2*1
6!=6*5*4*3*2*1
1!=1

18. Jump Statements – break &
continue
break statement in python is used to
terminate the containing loop for any
given condition. Program resumes from
the statement immediately after the
loop
Continue statement in python is used to
skip the statements below continue
statement inside loop and forces the
loop to continue with next value.

19. Example –
break
for i in range(1,20):
if i % 6 == 0:
break
print(i)
print(“Loop Over”)
The above code produces output
1
2
3
4
5
Loop Over
when the value of i reaches to 6 condition will becomes
True and loop will end and messageV“IN
