Day 2 - Beginner - Understanding Data Types and How to Manipulate Strings

19. Python Primitive Data Types.py

#Data Types

#String

"Hello"[4]

print("123" + "345")

#Integer

print(123 + 345)

123_456_789

#Float

3.14159

#Boolean

True
False

20. Type Error, Type Checking and Type Conversion.py

# num_char = len(input("What is your name?"))
# new_num_char = str(num_char)
# print("Your name contains " + new_num_char + "charackters")

a = float(123)
print(type(a))

print(70 + float("100.5"))
print(str(70) + str(100))

21. [Interactive Coding Exercise] Data Types.py

two_digit_number = input()
# 🚨 Don't change the code above 👆
####################################
# Write your code below this line 👇
first_digit = int(two_digit_number[0])
second_digit = int(two_digit_number[1])

#Add the integers together
two_digit_numbers = first_digit + second_digit

print(two_digit_numbers)

22. Mathematical Operations in Python.py

# 3 + 5
# 7 - 4
# 3 * 2
# 6 / 3
# 2 ** 3

#PEMDAS
# ( )
# **
# * /
# + -

print(3 * 3 + 3 / 3 - 3)
print(3 * (3 + 3) / 3 - 3)

23. [Interactive Coding Exercise] BMI Calculator.py

height = input()
weight = input()
# Your code below this line 👇
weight_as_int = int(weight)
height_as_float = float(height)
# Using the exponent operator **
bmi = weight_as_int / height_as_float ** 2
# or using multiplication and PEMDAS
bmi = weight_as_int / (height_as_float * height_as_float)

bmi_as_int = int(bmi)
print(bmi_as_int)

24. Number Manipulation and F Strings in Python.py

score = 0
height = 1.8
is_winning = True
#f-String
print(f"Your score is {score}, your height is {height}, and that yo're winning is {is_winning}")

25. [Interactive Coding Exercise] Life in Weeks.py

age = input()
# 🚨 Don't change the code above 👆
# Write your code below this line 👇
years = 90 - int(age)
weeks = years * 52

print(f"You have {weeks} weeks left.")

26. Day 2 Project: Tip Calculator.py

#If the bill was $150.00, split between 5 people, with 12% tip. 
#Each person should pay (150.00 / 5) * 1.12 = 33.6
#Round the result to 2 decimal places.
print("Welcome to the tip calculator!")
bill = float(input("What was the total bill? $"))
tip = int(input("How much tip would you like to give? 10, 12, or 15? "))
people = int(input("How many people to split the bill?"))

tip_as_percent = tip / 100
total_tip_amount = bill * tip_as_percent
total_bill = bill + total_tip_amount
bill_per_person = total_bill / people
final_amount = round(bill_per_person, 2)
