Python - Week 3 - Lists, Tuples, Slicing, Math Functions

This week I tried another problem from github:

Write a program that calculates and prints the value according to the given formula:
Q = Square root of [(2 * C * D)/H]

Following are the fixed values of C and H:
C is 50. H is 30.
D is the variable whose values should be input to your program in a comma-separated sequence.

Example
Let us assume the following comma separated input sequence is given to the program:
100,150,180
The output of the program should be:
18,22,24

Some interesting findings from this program:

  1. The import in Python is done using 'from ... import ..' statement. This is used in our program to use round and sqrt functions.
  2. Tuple is an immutable sequence type. Functionally, they’re used to represent fixed collections of items.
  3. print function takes an argument which by default is '\n'. In our case, we are using a different end character ','
  4. Slicing is a way to extract an entire section (slice) in a single step.
  5. printSeries[0:-1] - is used here to slice the list starting from index 0 until one but last item. printSeries[-1] is the last item in list.

Python - Week 8 - Dictionaries, Tuples, Sorting and Filtering

I spent last week understanding Python's sorting with Tuples and Dictionaries. Here is the first snippet that demonstrates how tuples are sorted. You are required to write a program to sort the (name, age, height) tuples by ascending order where name is string, age and score are numbers. The tuples are input by console. The sort criteria is: 1: Sort based on name; 2: Then sort based on age; 3: Then sort by score. The priority is that name > age > score. If the following tuples are given as input to the program: Tom,19,80 John,20,90 Jony,17,91 Jony,17,93 Json,21,85 Then, the output of the program should be: [('John', '20', '90'), ('Jony', '17', '91'), ('Jony', '17', '93'), ('Json', '21', '85'), ('Tom', '19', '80')] Here is the code: The code looks pretty concise, as if not much has been accomplished. But there are few points worth me...

Python - Week 5 - Comprehensions

As I settle in new job in a new country, starting February, I am making additional efforts to learn Python. So I will tackle a problem this week, with multiple solutions, each more Pythonic than the previous one. Here is the problem statement: Write a program which accepts a sequence of comma separated 4 digit binary numbers as its input and then check whether they are divisible by 5 or not. The numbers that are divisible by 5 are to be printed. Example: 0100,0011,1010,1001 Then the output should be: 1010 I deviated from the problem statement (not a good thing!). But I wanted to learn new tricks with Python. So I will excuse myself here. The way I approached the problem was to take a number (num) and find all binaries starting from 0 until num. Now for each of the binary, I checked if the equivalent decimal is divisible by 5. Some interesting points to note: Line 7 shows a way to convert a number to its binary string. Here b stands for binary and it uses forma...
