You can append any String to a StringBuffer by using its append method, eg

StringBuffer sb = new StringBuffer("pattern is ");
String pattern = "/^([0-9]{2})\/([0-9]{2})\/([0-9]{4})$/"; // will need to escape the \ chars as \
sb.append(pattern);

Hi!
I have two tables, I will call them first-half and second-half (of the year)

Table: first
id jan feb mar apr
-----------------------
2 80 90 70 60
3 50 40 60 30
Table: second
id jan feb mar apr
-----------------------
2 50 70 60 90
3 80 60 50 ...

from turtle import *
import random
def allTriMedian (w=300):
speed (0)
vertices = []
point = turtle.Point(x,y)
for i in range (3):
x = random.randint(0,300)
y = random.randint(0,300)
vertices.append(trutle.Point(x,y))
point = turtle.Point(x,y)
triangle = turtle.Polygon(vertices)
a = triangle.side()
b = triangle.side()
c = triangle.side()
m1 = tirangle.median
m2 = triangle.median ...
