String Functions
Add comments to all programs to explain what your code does.
If you get stuck make sure you ask. Work with the people beside you.
(1)
Write a program that asks the user to enter two Strings. The
program should:
 Print each String
 Print the length of each String
 Print the first String in uppercase and the second in
lowercase
 Print the character at the second position in the first String.
Remember to use the methods that go with strings
(2)
Write a program that asks the user to enter a five-letter word.
The program should print out the word. The program should also
print each character in the word on a new line.
For example, given the String “Hello” the program should print:
Hello
H
e
l
l
o
(3)
Write a program that prints each of the characters of a word in
reverse (print the last char first). For example, given the String
“Hello” the program should print:
o
l
l
e
H
(4)
Write a program that asks the user to enter their first name and
their second name. The program should then print a welcome
13 | P a g e
Programming Algorithms Computational Thinking
message as follows:
Welcome! <first name> <second name>.
Reminder: print(output1,output2,output3)
(5)
Write a program that asks the user to enter a three digit number.
The program should print the sum of the individual digits in the
number.
For example, if the user enters 123, the program should print:
The sum of the digits is 6.
Hint: A string is made up of slots, so for example the String 123 is:
2
1
Slot 0
1
2
3
So if you want slot 1 for the String you would say:
variable_name[1]
The last character in the String can be referenced as either the
last position or -1.
(6)
Write a program that asks the user to input their first name, their
middle initial and their surname. The program should output their
name in the following format, irrespective of whether capital
letters were used or not:
Welcome! John A. Griffin
Remember to go back through all the String methods
(7)
In python we can combine the same data types together. For
instance we can say 1+1 or 1.5 + 3.4. We could do the same for
Strings. Lets say we have 2 Strings:
1.
2.
first=”John”
last=”Doe”
If we want to combine them we would write:
full=first+last
14 | P a g e
Programming Algorithms Computational Thinking
This would result in :
JohnDoe
Try this with your name.
(8)
Write a program that allows the user to input a string. Then using
the indexes of the string change all the vowels to ‘ ! ‘:
Example:
Enter a String : Mine
M!n!
In Python there are built in features like the .upper(), .lower()
methods. We also have a .replace() method.
To use it we will take the above example:
“Mine.replace(‘i’,’!’)”
M!ne

and the largest one should be printed to the screen, in both in
Celsius value and Fahrenheit value.
Hint: Think about how you will choose which one is bigger. Say if
16 | P a g e
Programming Algorithms Computational Thinking
x > y is true, what would you print out first?
(5)

You can’t have a lie in today
(7)
Monkey Trouble
There are 2 monkeys together. The zoo keepers have to be careful,
if the 2 monkeys are smiling or neither of the monkeys are smiling
then there is a problem. However if only one of the monkeys are
smiling then there is no problem.
Write a program to see if there is a problem
A sample output would be:
Is monkey 1 smiling?
No
Is monkey 2 smiling?
Yes
There is no problem
Hint: use Booleans. So No would be false and yes would be true
(8)

Create a dictionary such that the key is a person’s PPS number and
the value is their date of birth representing with a string, for
example: 12122004. The program should ask the user to enter a
person’s name and then print out their date of birth in the format:
12/12/2004.

Functions
Add comments to all programs to explain what your code does.
If you get stuck make sure you ask. Work with the people beside you.
(1)
Write a Python function called mySchool() which will print details
about your school to the screen (you can choose what to print
inside the function).
Remember how to define a function:
def nameOfFunction():
#Do Something
(2)
Write a Python function called squareNo() which will print out the
square (number * number) of each number from 0 to 10.
(3)
Write a Python function called timesTables() that will print the
times tables of some number.
A function can take a parameter:
def nameOfFunction(x):
#Do Something with x
(4)
Write a Python function called stars() which will print a row of
stars to the screen. You can decide how many stars to print.
(5)
Write a Python function called menu() which will print a sample
restaurant menu of your choosing to the screen.

Write a Python function that will take in two integer parameters
and prints the sum of these numbers, the difference of these
numbers and the product of these numbers.
A function can take more than one parameter:
def nameOfFunction(x,y):
#Do Something with x and y
(2)
Write a Python function that takes in three numbers and will check
to see which of the numbers is the biggest and which is the
smallest. The answers should be printed to the screen.
Hint: there are a 6 comparison statements in total,
First one:
if (x<y and y<z and y<z):
print(x,"is the smallest")
print(y)
print(z,"is the biggest")
(3)
Write a Python function that takes in a String as input. Using a
while loop go through each character in the String and print it to
the screen one at a time.
Remember how to loop through a String
while condition:
#Do something
(4)
Write a Python function that will take in a String and a number as
parameters and prints the inputted string the amount of times
corresponding to the number. For example, if the parameters are
Hello and 4 the program should print:
Hello Hello Hello Hello

Remember you will have to cast the number into an int
int(input(“Enter a number”))
(5)
Write a Python function called numbers() which accepts a number
between 1 and 10 as a parameter. If a number greater than 10 or
less than 1 the program should print an error message. Otherwise
it should print the word for that number. For example, if the user
enters 4, the program will print four.
Remember your code from Lesson 13 question 6
(6)
Write a Python function that accepts a single letter as a
parameter. If the letter is a vowel it should print a message to
state this. Otherwise it should print not a vowel.
Remember when comparing characters:
char==”a”

Write a Python function that will take in a number representing a
distance in centimetres. It should return the equivalent of the
number in metres (1m = 100cm).
Remember to return a value from a function follow this syntax
def somefunction()
return some value or variable
(2)
Write a Python function to take in a parameter of type String.
Your procedure should use a loop to go through each character of
the String and count them. It should return this total to a variable
outside the procedure and print it to the screen.
Hint: do this question using a for loop. Do not use the length
function.
(3)
Write a Python function that will calculate how much VAT to pay on
a purchase. Your procedure should take in a value and then add
23% VAT to it. The answer should be returned to the code outside
the procedure and the answer displayed on the screen with the
original value.
(4)
Write a Python function which will take in two numbers one
representing the speed of a car (in km/hr) and another
representing the time taken (in hrs) to travel a particular distance.
Your function should calculate and return the distance travelled
using the formula:
Distance = Speed * Time
