Task

In this assignment you will write a function to calculate the square root of a number using the Babylonian method. You can search for that method, it will be easy to find.

The function should receive a number and return floating point number. Obviously you should test your function, so create a main program that asks the user a value, calculates the square root and displays that.

Task

So for this assignment I would like to see you create a function that receives as parameter the name of a file (this would be a string value like data.txt) and your function counts the number of lines and the number of characters in the file which it returns as a single value (but with two values). You will want to look at how to use and return a tuple from a function and how to open and read text files line by line.

Task

Write a function that receives four parameters: x1, y1, x2, y2 which are all floating point values.

The function is called distance and returns (float) the distance between x1,y1 and x2,y2 on the cartesian coordinate plane.

Solution:

 Task

Write a function that calculates returns the “nth” Fibonacci number where we define a function over the Fibonacci numbers mapping the naturals (starting with zero) to the Fibonacci series. So fibonacci(0) returns 0, fibonacci(1) returns 1, fibonacci(2) returns 1 and so on. Note that we are using the modern definition where the sequence starts with zero. You should try to implement this with two solutions: one with a loop and one with recursion.

Recursion solution:

During the “Taller Vertical” week, I had the opportunity to learn basic html coding, in this post I’ll explain easily how it works.

First of all, let me explain a bit some concepts and how each one works. html just provides the structural elements, CSS focuses in how to make that structure useful and atractive, and finally JavaScript has the power to give dynamism and build web applications completely functional.

To create your file you need to save it with the extension “.html”, this is to make it recognizable to our web browser.

1. Define a function max() that takes two numbers as arguments and returns the largest of them. Use the if-then-else construct available in Python. (It is true that Python has the max() function built in, but writing it yourself is nevertheless a good exercise.)

2. Define a function max_of_three() that takes three numbers as arguments and returns the largest of them.

3. Define a function that computes the length of a given list or string. (It is true that Python has the len() function built in, but writing it yourself is nevertheless a good exercise.)

4. Write a function that takes a character (i.e. a string of length 1) and returns True if it is a vowel, False otherwise.

5. Write a function translate() that will translate a text into “rövarspråket” (Swedish for “robber’s language”). That is, double every consonant and place an occurrence of "o" in between. For example, translate("this is fun") should return the string "tothohisos isos fofunon".

6. Define a function sum() and a function multiply() that sums and multiplies (respectively) all the numbers in a list of numbers. For example, sum([1, 2, 3, 4]) should return 10, and multiply([1, 2, 3, 4]) should return 24.

7. Define a function reverse() that computes the reversal of a string. For example, reverse("I am testing") should return the string "gnitset ma I".

8. Define a function is_palindrome() that recognizes palindromes (i.e. words that look the same written backwards). For example, is_palindrome("radar") should return True.

9. Write a function is_member() that takes a value (i.e. a number, string, etc) x and a list of values a, and returns True if x is a member of a, False otherwise. (Note that this is exactly what
