Exercise 1 (solution)

In this notebook you do your first steps in Python

Task 1: Hello World

define a function called hello that takes no arguments and prints Hello World! if it is called.

def hello():
    print("Hello World!")


hello()

Task 2: Strings

a = "I like programming"

Split the variable a into three words and assign these words to the variables a1, a2 and a3.

a1, a2, a3 = a.split()
a2

Task 3: Dictionaries

define a dictionaries that maps names to a level of Python knowledge. As names you can take your name and the names of a few friends. The Python knowledge should be rated on a scale from 0 to 10.

names_to_skills = {
    "Janos": 8,
    "Tobi": 10,
    "Mariam": 9,
}

Now loop over the keys and values of this dictionary and print a nicely formatted message. For example for me, the message that should be printed is:

'Janos has a python level of 8.'

for name, level in names_to_skills.items():
    print(f"{name} has a python level of {level}")

Task 4: Lists

Write a loop that takes that adds the next eight Fibonacci numbers to the list [1, 1]

numbers = [1, 1]
for _i in range(8):
    numbers.append(numbers[-2] + numbers[-1])

numbers
