Tuple
Create a tuple called tuple1 that contains 1, 2, 3, 4, 5
tuple1 = (1,2,3,4,5)
Create a set called set1 that contains 1, 2, 3, 4, 5
set1 = {1,2,3,4,5}
What are the two things included in a dictionary?
Key, Value
What is the symbol for modulo?
And what does it mean?
%, it means the remainder from an integer division.
Write a program that counts by 5, starts at zero and stops when it is over 100.
(Using while loop)
num = 0
while num < 100:
num = num + 5
print(num)
Does Tuple allow duplication of values?
Yes
Does Set allow duplication of values?
No
Create a dictionary called dict1 that contains 1, 2, 3 with their corresponding alphabet. The alphabet being the key.
dict1 = {"a":1, "b":2, "c":3}
Write a code that can find out the length of a list?
list1 = [ 1, 2, 3, 4, 5]
What is the answer?
print(len(list1))
5
Write a function called fun that takes in 3 arguments: first name, last name and the age of a person. And call the function so that is will print out the following:
Hello, I am FirstName LastName and I am Age years old.
(Function uses def)
def fun(fname, lname, age):
___print("Hello, I am", fname ,lname, ",and I am", age ,"years old.")

How do we create a random number generator thats chooses a number between 1 - 10.
import random
num = random.randint(1,10)
print(num)
Create a program that rolls a 20 sided dice randomly. And it keeps rolling until we rolled a 20.
import random
num = 0
while num != 20:
num = random.randint(1,20)
print(num)
How to change the tuple from to include 1,2,3,4,5,6; and how to change the tuple to 1,2,3,4.
Tuple is unmutable / unchangeable so that means in order to have change the original tuple you have to create a new one.
tuple1 = (1,2,3,4,5,6)
tuple1 = (1,2,3,4)
How to change a set from the original to include 1,2,3,4,5,6; and how to change a set to 1,2,3,4.
A Set is mutable / changeable so that means in order to have change the original tuple you add and remove.
set1.add(6)
set1.remove(5)
set1.pop(5)
set1.discard(5)
How to print a value from dict1, so it will print out 1.
print(dict1.get("a"))
Write a program that takes an input and output if the integer is even or odd.
num = int(input("Enter a number"))
if (num % 2 == 0):
print("It is even")
else:
print("It is odd")
Write a program that flips a coin until we exit the loop and counts the total of heads and tails.
(random and while)
import random
print("Welcome to the Python coin flip")
headC = 0
tailC = 0
while input("Press enter to flip the coin or type -1 to exit: ") != "-1":
coin = random.randint(0,1)
if(coin == 0):
print("Heads")
headC+=1
if(coin == 1):
print("Tails")
tailC+=1
print("Total Heads: " , headC , ", Total Tails: " , tailC)
Write a program to find the sum of the following tuple:
tuple1 = (18, 29, 45, 37, 56)
answer = 185
tuple1 = (18, 29, 45, 37, 56)
sum = 0
for num in tuple1:
___sum = num + sum
print (sum)
What will be printed out?
set1 = {12, True, 5.0, True, "apple", "banana", "cherry", "apple", 0, 2}
print(set1)
{12, True, 5.0, "apple", "banana", "cherry", 0, 2}
How to change a dictionary from the original to include a1,b2,c3,d4; and how to change a set to a1,b2.
dict1["d"] = 4
dict1.update({"d" : 4})
dict1.pop("c")
Write a program that takes an input of string and output the letter entered is a vowel or consonant.
letter = str(input("Enter a letter"))
if(letter =='a'):
print("vowel")
elif(letter =='e'):
print("vowel")
elif(letter =='i'):
print("vowel")
elif(letter =='o'):
print("vowel")
elif(letter =='u'):
print("vowel")
else:
print("consonant")
Write a program that finds the min and max of the following list:
res = [70 , 80, 90, 100, -60, -50 , -40]
(for loop)
res = [70 , 80, 90, 100, -60, -50 , -40]
max = res[0]
for num in res[1: ]:
if(num > max):
max = num
print (max)
min = res[0]
for num in res[1: ]:
if(num < min):
min = num
print (min)
