(1)

Indexing

Given a string of any length named s.

Extract and then print the first and last characters of the string

(with one space between them).

For example, given

s = 'abcdef'

The output will be

a f

Use the input statement provided in the skeleton:

s = input("Input a string: ")

(2)

Slicing

Given a string named s, move the first 3 letters to the back of the string.

Print it.

For example, given s = "magic tortoise"

will output

ic tortoisemag

Use the input statement in the skeleton:

s = input("Input a string: ")

(3)

Write code which prints the index location of each

letter 'o' in the string, one location per line of output.

Hint: enumerate() is your friend!

Given the string s:

happiness is when what you think, what you say, and what you do are in harmony. - gandhi

the output will be:

24

40

58

62

75

Use the input statement in the skeleton:

s = input("Input a string: ")

(4)

Formatting.

Given input that represents a floating point number, that is, made up of digits and at least one decimal point, convert the input to a float and print it with the following specifications:

* field width of 12

* 2 decimal digits of precision

* right justified

For example, if the input is

1234.56789

The output will be

1234.57

Note the five spaces to the left of the digit 1.

Use the input statement in the skeleton:

s = input("Input a float: ")

(5)

Collect Digits

Given a string of any length, extract the numbers (digits) and print them on one line without spaces.

Hint 1: one way to do this is to start with an empty string, concatenate each digit onto the string and at the end simply print the string.

Hint 2: isdigit() is your friend.

For example, given this string:

some 1! likes 2 put 14 digits, in 3 strings

The output will be

12143

Use the input statement in the skeleton:

s = input("Input a string: ")

(6)

String Methods.

Given a name in the format

lastname, firstname

where there is exactly one comma and exactly one space

transform the name into the format

first_initial. lastname

where

* first_inital and lastname are both capitalized

* there is exactly one period and space following the first_initial

For example, given s =

ghandi, mahatma

the output will be

M. Ghandi

Use the input statement in the skeleton code:

name = input("Input a name: ")
