Using while/for

What will be the output of the following code
for c in range(25,15,-2):
    c = c + 5
    print(c, end=' ')

Generate the Fibonacci series 0 1 1 2 3 5 8…..n ( use while..read n)

Reverse a Number ( i/p: 123 o/P 321).Check whether th reverse is same as original number ( palindrome)

Check whether the given 3 digit number is Armstrong Number.

Eg:153 ( 1+125+27=153) sum of cubes of digits=number.

Check whether the given number is a Krishnamurti number( Krishnamurthy Number: It is a number which is equal to the sum of the factorials of all its digits.Use factorial() function from math
For example : 145 = 1! + 4! + 5! = 1 + 24 + 120 = 145 which is a Krishnamurti Number.

Check whether the given number is Prime or not.

Write a python program to find the sum of the cosine series 1 - x^2/2! + x^4/4!-..n ( University question).

compare break,continue and pass statements in python.

Nested Loops(for/while)

Learning outcome:Working with Strings

Outcome:Learn String  Indexing and slicing, programming with strings

Consider the string str="Python Programming by Yourname" ( Replace Yourname with your first name)
Write statements in python to implement the following
a) To display the last four characters.
b) To display the substring starting from index 4 and ending at index 8.
c) Find the length of the string,min and max(characters)
d) To trim the last four characters from the string.
e) To trim the first four characters from the string.
f) To display the starting index of the substring 'gr'.
g) To change the case of the given string.( small letter to capital and capital to small)
h) To check if the string is in title case.
i) To replace all the occurrences of letter 'm' in the string with '*'

j)reverse the string

k)count the occurrence of the character ‘m’

l)characters in even positions 0,2,4,…..

m) characters in even positions 0,2,4,…..in reverse order
