Let's do something fun with python

Suppose you have $100, which you can invest with a 10% return each year. Add code to calculate how much money you end up with after 7 years, and print the result.

# Addition, subtraction

print(5 + 5)

print(5 - 5)

# Multiplication, division, modulo, and exponentiation

print(3 * 5)

print(10 / 2)

print(18 % 7)

print(4 ** 2)

# How much is your $100 worth after 7 years?

print(100 * (1.1) ** 7)

Write a function to calculate bmi, it should be able to convert numbers into float. 

def bmi_cal():

    x = float(input("what is your height in meters"))

    y = float(input("what is your weight in kg?"))

    bmi = y/x ** 2

    print(bmi)

bmi_cal()

Create a conditional sublist of dictionary. 

# Create a dictionary with some key-value pairs

my_dict = {"key1": "value1", "key2": "value2", "key3": "value3"}

# Get a sublist of the dictionary containing key-value pairs for "key1" and "key2"

sublist = {key: value for key, value in my_dict.items() if key in ["key1", "key2"]}

# Print each key and value in the sublist

for key, value in sublist.items():

    print(f"Key: {key}, Value: {value}")
