Now it’s your turn to try! Give this a go yourself.

Use Python to calculate $(((1+2)*3)/4)^5$

Tip: remember that you can use a**b to calculate a to the power of b. 

 

x = (((1+2)*3)/4)

b = x ** 5

print(b)

 

 

 

 

 

 

Arithmetic operators

Python can operate with numbers using the usual mathematical operators, and some special operators, too. These are all of them (we'll explore the last two in later videos).

• a + b = Adds a and b

• a - b = Subtracts b from a

• a * b = Multiplies a and b

• a / b = Divides a by b

• a ** b = Elevates a to the power of b. For non integer values of b, this becomes a root (i.e. a**(1/2) is the square root of a)

• a // b = The integer part of the integer division of a by b

• a % b = The remainder part of the integer division of a by b

Writing a computer program.

Creating a report of how much each sales person has sold in the last month.

Correct

You nailed it! Creating reports based on data are a great example of things that can be automated.

Setting the home directory and access permissions for new employees joining your company.

Correct

Spot on! The process of setting up the account for a new employee is usually repetitive and most of it can be automated.

Designing the new webpage for your company.

Taking pictures of friends and family at a wedding.

This should not be selected

Not quite. While there might be some automation available for taking the picture and the right time and post-processing them, taking pictures is still a creative process. Consider reviewing our videos on automation.

Populating your company's e-commerce site with the latest products in the catalog.

Question 4

What are some characteristics of the Python programming language? Check all that apply.

Python programs are easy to write and understand.

Correct

Right on! Because the syntax used by Python is similar to the one used by the English language, Python programs are easy to write and understand.

The Python interpreter reads our code and transforms it into computer instructions.

Correct

You nailed it! We write our code using Python's syntax and semantics, and the interpreter transforms that into instructions that our computer executes.

It's an outdated language that's barely in use anymore.

We can practice Python using web interpreters or codepads as well as executing it locally.

Correct

Awesome! We can practice writing Python code with many different tools available to us, both online and offline.

Question 5

How does Python compare to other programming languages?

Python is the only programming language that is worth learning.

Each programming language has its advantages and disadvantages.

It's always better to use an OS specific language like Bash or Powershell than using a generic language like Python.

Programming languages are so different that learning a second one is harder than learning the first one.

Correct

Woohoo! Each language has its pros and cons. The best language to choose will depend on the problem you are trying to solve.

Question 10

Most hard drives are divided into sectors of 512 bytes each. Our disk has a size of 16 GB. Fill in the blank to calculate how many sectors the disk has.

Note: Your result should be in the format of just a number, not a sentence.

 

disk_size = 16*1024*1024*1024

sector_size = 512

sector_amount = disk_size / sector_size

print(sector_amount)

Learning function from google.

def hey(name, department):

hey("Sayed Amy","Software developer")

hey("Sah", "coder")

Solve the question:        

Do you think you can flesh out your own function? I think you can! Let’s give it a go.

Flesh out the body of the print_seconds function so that it prints the total amount of seconds given the hours, minutes, and seconds function parameters. Remember that there are 3600 seconds in an hour and 60 seconds in a minute.

This is not valid answer. This is a demo.

def print_seconds(hours, minutes, seconds):

print(seconds)

print_seconds(1,2,3)

 

 

 

 

 

Solve the problem:

Ques: 1

Use the get_seconds function to work out the amount of seconds in 2 hours and 30 minutes, then add this number to the amount of seconds in 45 minutes and 15 seconds. Then print the result.

Solution:

def get_seconds(hours, minutes, seconds):

return 3600*hours + 60*minutes + seconds

amount_a = get_seconds(2,30,0)

amount_b = get_seconds(0,45,15)

result = amount_a + amount_b

print(result)

Ques:2

Ready to try it yourself? See if you can reduce the code duplication in this script.

In this code, identify the repeated pattern and replace it with a function called month_days, that receives the name of the month and the number of days in that month as parameters. Adapt the rest of the code so that the result is the same. Confirm your results by making a function call with the correct parameters for both months listed.

Sol: 

# REPLACE THIS STARTER CODE WITH YOUR FUNCTION

def month_days(month, days):

june_days = 30

print("June has " + str(june_days) + " days.")

july_days = 31

print("July has " + str(july_days) + " days.")

 

month_days(30,1)

Here is your output:
June has 30 days.
July has 31 days.

Nice work! You're getting acquainted with some interesting
coding practices to reduce code duplication.

 

 

Question: 3

This function to calculate the area of a rectangle is not very readable. Can you refactor it, and then call the function to calculate the area with base of 5 and height of 6? Tip: a function that calculates the area of a rectangle should probably be called rectangle_area, and if it's receiving base and height, that's what the parameters should be called.

 

def f1(x, y):

z = x*y # the area is base*height

print("The area is " + str(z))

Solution:

def rectangle_area(base,height):

area = base*height # the area is base*height

print("The area is " + str(area))

rectangle_area(5,6)

Here is your output:
The area is 30

Wonderful! You're learning how to write self-documenting
code, that will be easier to read & reuse.

Question: 4

What is the purpose of the def keyword?

Used to define a new function

Used to define a return value

Used to define a new variable

Used to define a new parameter

Correct

Awesome! When defining a new function, we must use the def keyword followed by the function name and properly indented body.

 

 

 

Question: 5

Let's revisit our lucky_number function. We want to change it, so that instead of printing the message, it returns the message. This way, the calling line can print the message, or do something else with it if needed. Fill in the blanks to complete the code to make it work.

 

def lucky_number(name):

number = len(name) * 9

print = "Hello " + name + ". Your lucky number is " + str(number)

pass

print(lucky_number("Kay"))

print(lucky_number("Cameron"))

Sol:

 

 

Question: 5

What are the values passed into functions as input called?

 

Variables

Return values

Parameters

Data types

 

 

 

 

 

Question: 6

This function compares two numbers and returns them in increasing order.

1. Fill in the blanks, so the print statement displays the result of the function call in order.

Hint: if a function returns multiple values, don't forget to store these values in multiple variables

Sol:

# This function compares two numbers and returns them

# in increasing order.

def order_numbers(number1, number2):

if number2 > number1:

return number1, number2

else:

return number2, number1

# 1) Fill in the blanks so the print statement displays the result

# of the function call

smaller,bigger = order_numbers(100, 99)

print(smaller, bigger)

output:

99 100

Correct

Nice! You remembered how to accept multiple return values
from a function. You’re ready for the next lesson!

 

 

 

 

Question: 7

The is_positive function should return True if the number received is positive and False if it isn't. Can you fill in the gaps to make that happen?

solution:

def is_positive(number):

if number > 0:

return True

else:

return False

 

 

is_positive(-5) returned False
is_positive(0) returned False
is_positive(13) returned True

Well done, you! You're starting to
master conditional expressions!

Question: 8

The number_group function should return "Positive" if the number received is positive, "Negative" if it's negative, and "Zero" if it's 0. Can you fill in the gaps to make that happen?

def number_group(number):

if ___:

return "Positive"

elif ___:

return ___

else:

___

print(number_group(10)) #Should be Positive

print(number_group(0)) #Should be Zero

print(number_group(-5)) #Should be Negative

 

Solution:

def number_group(number):

if number > 0:

return "Positive"

elif number < 0:

return "Negative"

else:

return "Zero"

print(number_group(10)) #Should be Positive

print(number_group(0)) #Should be Zero

print(number_group(-5)) #Should be Negative

Here is your output:
Positive
Zero
Negative

Well done! You're progressing so fast!

Conditionals Cheat Sheet

 

Comparison operators

• a == b: a is equal to b

• a != b: a is different than b

• a < b: a is smaller than b

• a <= b: a is smaller or equal to b

• a > b: a is bigger than b

• a >= b: a is bigger or equal to b

 

 

Logical operators

• a and b: True if both a and b are True. False otherwise.

• a or b: True if either a or b or both are True. False if both are False.

• not a: True if a is False, False if a is True.
  

 

 

Branching blocks

In Python, we branch our code using if, else and elif. This is the branching syntax:

if condition1:

if-block

elif condition2:

elif-block

else:

else-block

 

 

 
Remember: The if-block will be executed if condition1 is True. The elif-block will be executed if condition1 is False and condition2 is True. The else block will be executed when all the specified conditions are false.

 Question 2

Complete the script by filling in the missing parts. The function 
receives a name, then returns a greeting based on whether or not that 
name is "Taylor".

def greeting(name):

if ___ == "Taylor":

return "Welcome back Taylor!"

___:

return "Hello there, " + name

print(greeting("Taylor"))

print(greeting("John"))

Question 3

What’s the output of this code if number equals 10?

if number > 11:

print(0)

elif number != 10:

print(1)

elif number >= 20 or number < 12:

print(2)

else:

print(3)

 

enter output: 

Question 4

Is "A dog" smaller or larger than "A mouse"? Is 9999+8888 smaller or larger than 100*100? Replace the plus sign in the following code to let Python check it for you and then answer.

print("A dog" > "A mouse" )

print(9999+8888 > 100*100)

Select the right answer:

 

 

"A dog" is larger than "A mouse" and 9999+8888 is larger than 100*100

"A dog" is smaller than "A mouse" and 9999+8888 is larger than 100*100

"A dog" is larger than "A mouse" and 9999+8888 is smaller than 100*100

"A dog" is smaller than "A mouse" and 9999+8888 is smaller than 100*100
