Running python
Jupyterhub
- Log into jupyter.math.bme.hu with your leibniz user and password
- We will use Python 3
- this is similar as you would run the following on your own machine
jupyter notebook
leibniz
- type this into your konsole:
python3
- you can stop by typing:
exit()
Own machine
Install Anaconda, version 3.7 is needed!
- how to install Anaconda on windows
- You can use other distributions such as
Having Anaconda you can run several programs to interact with python:
- command line: python or ipython
- Spyder
- idle
- jupyter notebook
Exercises
Introduction
- Try the notebook from the lecture.
- download from wiki and upload it into jupyter.math.bme.hu
- Try a welcoming program (from terminal)!
- Try division (integer and float)
tocelsius
Write a python program that convets from Fahrenheit to Celsius
- See examples here
isaprime
Write a function that tells whether a number is a prime or not!
The function should be called isaprime and have one parameter:
- x, the number in question
The function should return True
or False
depending on the number.
For safety reasons, you can check the type and value of the input. Accept only positive integers!
If you get a non-integer or a non-positive integer, return None
roomtemp
According to Wikipedia a room has a temperature between 18°C and 25°C. Write a function that decides that for us.
The function should
- be called roomtemp
- have one parameter: degree the temperature of the room in Celsius degrees.
- return either one of the following strings depending on the temperature:
-
"Too cold!"
-
"Too hot!"
-
"OK"
-
Mind that there is a difference between print
and return
factorial
Write a python program which calculates n factorial.
without 2
You should divide a positive integer n with a power of two, until it is not divisible by 2.
Call the function withouttwo
with one parameter:
- n, a positive integer
- Return the number divided by the greatest possible power of two.
For example
1 -> 1 2 -> 1 3 -> 3 4 -> 1 6 -> 3 7 -> 7 9 -> 9 10 -> 5 100 -> 25
Pattern Number
Write a python program which has the following output:
1 22 333 4444 55555 666666 7777777 88888888 999999999
Fibonacci Series
Write a Python program to get the Fibonacci series between 0 to 50.
