Career Principles - Python Part 2

Question 1

What are the most popular math operators?

Answer 1

+, - , *, /

** which means an exponent
% which gives you the remainder

Question 2

What are the most common comparison operators?

Answer 2

> < greater than, less than

== this is the equal operator

!= this is the not equal operator. for example, 3!=2, would return true

Question 3

What are the common logical operators?

Answer 3

and, or, and not

Question 4

What are some of the popular math functions

Answer 4

Max () /Min ()
Sum ()
ABS ()
Round ()
Len () - counts the values

Question 5

What is the code to sum 1, 2, 3, 4?

Answer 5

you can’t do sum(1, 2, 3, 4) as it will result in a error

you have to one of the following two ways:

number = (1, 2, 3, 4)
sum(number)

OR

sum([1, 2, 3, 4])

Question 6

What is if/elif/else?

Answer 6

if: Used to check a condition. If the condition is true, the code under the if block runs.

elif: Stands for “else if.” It checks another condition if the previous if condition was false. You can have multiple elif statements.

else: Runs a block of code if none of the if or elif conditions were true. It’s optional but useful for handling cases where no conditions are met.

Question 7

Write the code for the following:

ask “Where is your passport from?”

and if they respond United States say “Great, go to the fast track”

for any other country say “Sorry, go to the slow track”

Answer 7

passport = input(“where is your passport from?”)

if passport == “United States”:
print(“Great, go to the fast track”)

else:
print(“Sorry, go to the slow track”

Question 8

Write the code for the following:

ask “Where is your passport from?”

and if they respond United States say “Great, go to the fast track”

 then ask "What is your age?"

 if older then 65 say "Go to the assisted track"
 if younger than 65 say "Go to the fast track"

for any other country say “Sorry, go to the slow track”

Answer 8

passport = input(“Where is your passport from?”)
if passport == “United States”:
print (“Great, go to the fast track”)
age = int(input(“What is your age?”))

if age >= 65:
 print("go to the assisted track")

 else: 
 print("go to the fast track")

else:
print(“sorry, go to the slow track”)

Question 9

Write the code for the following:

ask “Where is your passport from?”

and if they respond United States or Ireland

 then ask "What is your age?"

 if younger than 18 say "Go to the under age 
 track"
 if younger than 65 say "Go to the fast track"
 otherwise say "Go to the assisted track"

for any other country say “Sorry, go to the slow track”

Answer 9

passport = input(“Where is your passport from?”)

 if passport == "United States" or "Ireland":
 
 age = int(input("What is your age?"))

 if age < 18:
      print("go to the under age track")

elif age <= 65:
      print("go to the fast track")

 else: 
      print("go to the assisted track")

else:
print(“sorry, go to the slow track”)

Question 10

What is a for loop?

Answer 10

A for loop repeats a block of code for each item in a collection (like a list, string, or range of numbers)

first you need to define the list, then you write
for name in listname, print(name)

Question 11

Write a for loop to print a list up to 4?

Answer 11

code:

for i in range(5):
print(i)

output:

0
1
2
3
4

note, you wrote 5 in the code but it prints up to 4

Question 12

write a for loop for the following fruits: apple, banana, and cherry

Answer 12

code:
fruits = [“apple”, “banana”, “cherry”]
for fruit in fruits:
print(fruit)

output:
apple
banana
cherry

Question 13

Write a for loop for a list up to 26 but skipping every other number?

Answer 13

for numbers in range(1, 26, 2):
print(numbers)

Output:

1,
3,
5,
7,
etc

Question 14

How to write a loop that returns the number of temps greater than 30.

for the following temps: 22, 27, 31, 32

Answer 14

code:

temperatures = [22,27,28,31,32]
threshold = 30
hot_day_count = 0

for temp in temperatures:
if temp > threshold:
hot_day_count +=1

print(“Day with temp above 30C: “, hot_day_count)

output:

Days with temp above 30C: 2

Question 15

What is the difference between a For Loop and While Loop

Answer 15

A For Loop runs for a list of items or a range and STOPs at the end of the list/range

Example:
For color in color_list:
do something to each color

A While Loop runs as long something is true. It only STOPs when it hits something that is False

Example:
While something_is_true:
do something continuously
