Python Code Example

Here is a short Python script to implement method 2 for generating the symbolic code for the nth iteration of the terdragon curve.

n = input("n = ")  #order of iteration
b = ['']
for k in range(1,3**(n-1)+1):  #mod 1,2 positions
    b += ['R','L','']
for k in range(1,3**(n-1)):    #multiples of 3 positions
    b[3*k] = b[k]
b = "".join(b[1:-1])           #convert list to string
print(b)
