How To Calculate If The Year Is Leap Year and How Many Days Are In The Month #PurePythonSeries — Episode #05

Fig 1. Image from What Is a Leap Year? By timeanddate.com

Who determined which months would have 30 or 31 days?

A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day.

A year that is not a leap year is a common year.

In the Gregorian calendar, each leap year has 366 days instead of 365, by extending February to 29 days rather than the common 28. These extra days occur in each year which is an integer multiple of 4 (except for years evenly divisible by 100, but not by 400). The leap year of 366 days has 52 weeks and two days, hence the year following a leap…

1 — PANDAS Series — How to Create From…

import pandas as pd

Let’s create four artifacts to see how to create a Series:

First, a List:

labels = ['a','b', 'c']

Second, another List:

my_data = [10,20,30]

Third, a Numpy array:

import numpy as nparr = np.array(my_data)

And Finally, forth, a Dictionary:

dict = {'a':10, 'b':20, 'c':30}

Create Series FROM LISTS

pd.Series(data=my_data, index=labels)a    10
b 20
c 30
dtype: int64

Or, ordering, first data, then labels:

pd.Series(my_data, labels)a…

Python Lambda Desmistification — #PurePythonSeries — Episode #00

This post attempts to demystify Lambda in Python.
Fig 1. Lambda Expression: lambda function:iterable

Simply put, a lambda function is just like any normal python function, except that it has no name when defining it, and it is contained in one line of code. A lambda function evaluates an expression for a given argument. You give the function a value (argument) and then provide the operation (expression) — From TowardsDatascience.com.

How To Format Strings in Python #PySeries#Episode 35

Hi, this is a quick note about strings in python.

Fig 1. Phyton quick notes about string formatting

Let’s get it on?

String Interpolation → Injects a variable into your string printing

. format()
. f-strings
print('This is a string {}'.format('INSERTED'))This is a string INSERTED

Multiples strings — when order matters!

print('{} {} {}.'.format('brown', 'quick', 'fox') )brown quick fox.

Positional arguments:

print('{1} {0} {2}.'.format('brown', 'quick', 'fox') )quick brown fox.

Or keywords arguments:

print('{q} {b} {f}'. format(b = 'brown', q = 'quick', f = 'fox'))quick brown fox

Float formatting follows “{value: width.precision f}”

result = 100/777

Printing directly:

print("The result was {}".format(result))The result was 0.1287001287001287

Or formatting the number:

print("The result was {r:1.3f}".format(r = result))The result was 0.129
