One and one and one is … – Minimum Viable Python

This is a post with executable code.

First, some code in R. When I first ran it in Visual Studio Code, I got an offer to install the R extensions (accepted).

Code

1 + 1 + 1

[1] 3

Code

quadrillion = 1000 * 1000 * 1000* 1000
erm_radius <- 6372795.477598   #Earth radius in meters
eartharea <- 4 * pi * erm_radius * erm_radius
print(eartharea/quadrillion)

[1] 510.352

Then, some code in python. When I first ran it in RStudio, I got an error message that looked like this:

(picture of an error message meaning: You didn’t install reticulate)

after that, I did this:

install-packages("reticulate")

and everything worked just fine

Code

from decimal import *

PI= Decimal('3.1415926535897931')
RADIUS= Decimal('6372795.477598')   #Earth radius in meters
RADIUS1 = RADIUS+1

# Formula for volume is four-thirds pi R cubed

m1 = 4 * PI / 3
V= m1 * RADIUS * RADIUS * RADIUS
V1= m1 * RADIUS1 * RADIUS1 * RADIUS1

print (V ," cubic meters")

1084122984296576747840.498564  cubic meters

Code

area = V1-V
print (area , " square meters")

510352085623125.659716  square meters

Code

quadrillion = 1000 * 1000 * 1000 * 1000 
print(quadrillion)

1000000000000

Code

print (area/quadrillion, "quadrillion square meters")

510.352085623125659716 quadrillion square meters
